Fannie Mae Rental Income Guidelines: 2026 Rules for Investment Properties and Multi-Unit Homes
Fannie Mae rental income guidelines determine when rent from an investment property, a multi-unit primary residence, an accessory dwelling unit, a departing residence, or another rental property can help a borrower qualify for a conventional mortgage. The rules are more detailed than simply taking 75% of the monthly rent.
Property type, occupancy, current housing expenses, landlord experience, tax return history, lease documentation, and whether the property is a long-term or short-term rental can all affect how much income an underwriter may use.
Fannie Mae made significant changes to its rental-income guidance on September 2, 2026. The revised Selling Guide reorganizes rental-income requirements into six sections and introduces new requirements for short-term rentals, departing residences, properties acquired within 45 days of a new mortgage application, and lease verification. Lenders may implement the updated rules immediately and must use them for applications dated on or after November 1, 2026. This guide explains the current rules in plain English so borrowers, real estate investors, loan officers, and real estate professionals can understand how rental income may affect mortgage qualification.
How Does Fannie Mae Calculate Rental Income?
For many long-term rental scenarios documented with a lease or market rent, Fannie Mae starts with 75% of the gross monthly rent. The remaining 25% accounts for potential vacancy and ongoing maintenance expenses. However, that does not mean every borrower gets to add 75% of the rent directly to qualifying income.
Under Fannie Mae’s September 2026 guidance, short-term rental income can be even more conservative. Certain short-term rental calculations use only 50% of documented market rent, rather than 75%, before subtracting PITIA.
The lender must determine if the borrower has a current housing payment, at least 12 months of property-management experience, whether tax returns should be used instead of a lease, and how the property’s full principal, interest, taxes, insurance, and association dues—commonly called PITIA—must be treated.
What Changed With Fannie Mae Rental Income in September 2026?
Fannie Mae stated that its rental-income policy had become increasingly complex and that lenders reported difficulty applying the prior guidance consistently.
The September 2, 2026, Selling Guide update therefore reorganized the rules and addressed several gaps.
Among the Most Important Changes Are:
- New qualifying requirements for short-term rental properties.
- Stronger standards for validating leases.
- A minimum lease-term requirement in certain situations.
- Restrictions involving family members and interested parties.
- A new method for evaluating a primary residence being converted into a rental.
- New requirements for investment properties purchased shortly before the new mortgage application.
- Additional documentation requirements to demonstrate that a lease has actually gone into effect.
Lenders can use these policies immediately, but they become mandatory for applications dated on or after November 1, 2026.
Why This Update Matters to Borrowers
A signed lease by itself may no longer answer the underwriting question. The underwriter may need evidence that the tenant moved forward with the lease, proof of rent payments or deposits, market-rent support, tax returns, property-management history, and documentation of the borrower’s existing housing payment. This is why rental income should be reviewed before pre-approval whenever possible, rather than after a borrower has already signed a purchase contract.
What Property Types Can Generate Fannie Mae Rental Income?
For rental income generated by the property being financed, Fannie Mae permits it in several situations.
Eligible Subject Properties Include:
- Two- to four-unit primary residences where the borrower occupies one unit.
- One- to four-unit investment properties.
- An eligible one-unit principal residence containing one accessory dwelling unit, subject to additional ADU restrictions.
Fannie Mae generally does not allow rental income from the portion of a principal residence occupied by the borrower or from a second home to qualify the borrower. Exceptions exist for qualifying boarder income and eligible accessory dwelling unit income.
Rental Income From Property Other Than the Home Being Financed
Fannie Mae is broader when rental income comes from a property that is not securing the new mortgage. The current Selling Guide states there is no restriction on property type when eligible rental income is derived from a non-subject property.
Fannie Mae guidelines can change. The lender and underwriter should always verify the current Fannie Mae Selling Guide applicable to the loan application.
The Guide provides commercial property as an example, provided the income satisfies documentation and qualification requirements. This does not mean every dollar of rent will automatically qualify. Tax returns, leases, mortgage obligations, property-management history, and the timing of ownership still matter.
Why Your Current Housing Payment Matters
One of the most misunderstood Fannie Mae rental income requirements involves the borrower’s current housing payment.
A qualifying housing payment may consist of:
- Monthly rent.
- PITIA or a leasehold payment on a mortgaged residence.
- Property taxes or a leasehold payment on a residence owned free and clear.
When a housing payment is not adequately documented in the credit file, the lender may need additional evidence, such as verification from a property management company, at least 6 months of bank statements or canceled checks, or proof of the most recent property tax payment.
Can a First-Time Investor With No Housing Payment Use Future Rental Income?
- This can be a problem.
- Fannie Mae requires the lender to document the borrower’s current housing payment before using the subject property’s rental income for qualifying.
- Therefore, someone living rent-free who wants to buy a rental property should not assume the property’s projected rent can be used to qualify the loan.
- This is one reason rental-income qualification should be calculated before a buyer starts making offers.
Fannie Mae’s 12-Month Property-Management Experience Rule
Property-management experience can determine whether positive rental cash flow becomes additional qualifying income or can merely help offset the property’s housing expense.
Under the current Selling Guide, lenders may use positive rental income as qualifying income only if the borrower has at least 12 months of property management experience.
If the borrower has no or less than 12 months of experience, qualifying rental income can generally only offset PITIA rather than create additional positive income beyond the property expense.
How Is 12 Months of Landlord Experience Documented?
Fannie Mae provides several possible methods. The lender may document experience through the borrower’s most recent individual federal income tax return showing rental income and 365 Fair Rental Days.BRental-property experience may also be documented through applicable business tax returns and Form 8825.
In some cases, leases may supplement tax returns when the property has been owned long enough, but the tax return lacks a full year of rental activity.
Fannie Mae also permits a fully executed lease dated at least 12 months before the mortgage application in some cases when the property has not yet appeared on the borrower’s tax returns.
Experience Changes the Calculation
Consider an Investment Property Producing $3,000 in Monthly Gross Rent:
Using the standard 75% calculation:
- $3,000 × 75% = $2,250 qualifying net rent before PITIA
- Assume the property’s full PITIA is $2,000.
The Adjusted Rental Income is:
- $2,250 − $2,000 = $250
- A borrower with at least 12 months of qualifying property-management experience may potentially use the positive $250 in qualifying.
For a borrower with less than 12 months of experience, that positive rental result generally cannot be treated as additional qualifying income; it is restricted to offsetting the property’s PITIA.
The Fannie Mae 75% Rental Income Rule
The “75% rule” is one of the most common questions about mortgages involving rental properties. When qualifying long-term rental income is based on a lease or applicable market rents, the lender generally multiplies gross monthly rent by 75%.
The other 25% accounts for vacancy and ongoing maintenance expenses.
Example of the 75% Rental Income Calculation
Suppose an investment property has a market rent of $2,400 per month.
The Initial Calculation is:
- $2,400 × 75% = $1,800
If PITIA on the property is $1,550:
- $1,800 − $1,550 = $250 adjusted net rental income.
If PITIA is Instead $2,000:
- $1,800 − $2,000 = -$200
- The $200 monthly rental loss generally increases the borrower’s obligations when calculating the debt-to-income ratio.
- A positive result may be treated differently depending on the borrower’s property-management history and whether the property is a principal residence or an investment property.
How Schedule E Rental Income Is Calculated
Once a rental property appears on the borrower’s federal income tax return, underwriting typically relies on actual rental-property history rather than multiplying the current lease by 75%. a cash-flow analysis using IRS Schedule E. \
Fannie Mae allows certain expenses on Schedule E to be added back when determining cash flow, including depreciation, mortgage interest, homeowners’ association dues, taxes, and insurance.
Documented non-recurring property expenses may also be considered. The resulting cash flow is divided by the applicable number of months and then evaluated with the property’s PITIA to determine qualifying rental income or loss.
Why Your Tax Return May Produce a Different Number Than Your Lease
A property renting for $3,000 today does not necessarily provide the borrower with $2,250 in qualifying rental income.
If the property is already established on Schedule E, underwriting may need to use its historical cash flow.
That is why borrowers should provide their tax returns and current leases at the start of the mortgage process rather than assuming current rent controls the calculation.
Rental Income From a Two-to-Four-Unit Primary Residence
Fannie Mae permits borrowers to use qualifying rental income from the other units of an eligible duplex, triplex, or fourplex when the borrower will occupy one unit as a primary residence. For a purchase transaction, Form 1025 or other applicable appraisal documentation is generally used to establish rental potential under the current Selling Guide.
When a lease transfers to the borrower, the lender may also need the fully executed lease and supporting documentation demonstrating that the contractual rent is reasonable relative to current market rents.
Living in One Unit Does Not Make All Rent Automatically Usable
The buyer must meet the current housing payment requirement. Property-management experience also affects whether positive rental income may be fully used or is restricted. The complete PITIA of the principal residence remains relevant to the debt-to-income calculation.
Fannie Mae’s general rental-income guidance specifically distinguishes the treatment of rental income associated with the borrower’s principal residence from income associated with a separate investment property.
For broader financing requirements on duplexes, triplexes, and fourplexes, keep this article focused on rental-income qualification. Use a separate internal article for Fannie Mae multi-unit down payments, loan limits, and occupancy requirements. This separation helps avoid keyword cannibalization.
Fannie Mae Rental Income From Investment Properties
One- to four-unit investment properties can produce qualifying rental income. For a purchase, the lender generally obtains applicable appraisal-based market-rent documentation and any lease that will transfer with the property. The standard calculation for a long-term rental purchase normally starts by multiplying gross rent by 75% and subtracting PITIA.
With at least 12 months of property-management experience, positive adjusted net rental income may generally be added to qualifying income.
With less than 12 months of experience, positive rental income generally only offsets PITIA. A negative result must be considered in DTI. Readers comparing traditional investment financing with alternative programs can also review Gustan Cho Associates’ guide to investment property loans.
Fannie Mae Lease Agreement Requirements
The September 2026 update makes lease documentation more important. A lease may be used to establish qualifying rental income in certain situations, including purchases where an existing lease transfers to the buyer, recently acquired rental properties that have not yet appeared on a tax return, properties affected by significant rental interruptions, properties first placed in service during the current calendar year, and other documented circumstances that the lender can justify.
Newly Executed Leases May Need at Least a Six-Month Term
When a new lease is dated within two months of the mortgage application, and the property is not on the borrower’s individual federal tax return, the lease generally must have a term of at least six months. The first rental payment must also be due no later than the first payment due date on the subject mortgage.
A Lease With a Family Member Can Be a Problem
For subject and non-subject properties that do not appear on the borrower’s most recent individual federal tax return, the lease cannot be with an interested party or a family member. This provides stronger evidence that the rental arrangement is an arm’s-length transaction rather than an agreement created mainly to qualify for the mortgage.
The Lender May Need Proof That Rent Is Actually Being Paid
A signed lease does not prove it has gone into effect. Depending on the situation, Fannie Mae permits documentation such as two consecutive months of bank statements or electronic rent transfers.
For a newly executed lease, documentation may instead include the security deposit and the first full month’s rent, along with evidence that the funds were deposited.
A qualifying third-party property management arrangement combined with evidence of recent rent payments can also be used in some circumstances.
Fannie Mae Departing Residence Rental Income
A departing residence is the borrower’s current primary home that will be vacated and converted into an investment property when the borrower purchases a new primary residence. Fannie Mae created a separate framework for departing-residence rental income in the September 2026 update. This rule is particularly important because lease agreements are not permitted to establish the rental income for the departing residence under the new policy.
How Is Market Rent Established on a Departing Residence?
The Lender May Use Documentation Such As:
- An appraisal containing market rent.
- Form 1007 for the borrower-occupied unit when applicable.
- Acceptable market-analysis tools.
Fannie Mae specifically lists sources such as Zillow, Redfin, and MLS as potential market-analysis tools, provided the lender obtains at least three comparable rental properties and follows the Guide requirements.
How Much Departing-Residence Rent Can Be Used?
- Gross market rent is multiplied by 75%.
- PITIA on the departing residence is then subtracted.
- If the result is positive, the rent may only offset the PITIA of the departing residence.
- If the result is negative, the rental loss must be included in the borrower’s debt-to-income ratio.
Additional Reserve Requirement for New Landlords
When the borrower has less than 12 months of property management experience, Fannie Mae requires the lender to verify six months of reserves covering the PITIA for the vacated property. This is in addition to reserve requirements for multiple financed properties.
Fannie Mae Short-Term Rental and Airbnb Income Guidelines
One significant change in 2026 involves short-term rental income. Fannie Mae defines a short-term rental as a furnished residential property typically rented for less than 30 consecutive days, rather than under a standard long-term lease.
Under the new policy, qualifying subject-property short-term rental income is limited to one-unit investment properties.
The property must also be legally permitted to operate as a short-term rental and comply with applicable local licensing and registration requirements. Short-term rental income cannot come from an ADU for this purpose.
Purchasing a Short-Term Rental Property
For a purchase transaction, the lender may use Form 1007 based on standard long-term rents or on qualifying, validated short-term rental market data. When short-term rental comparable data is used, Fannie Mae requires data on three comparable properties, including rental rates and the number of days each property was rented during the preceding calendar year.
Fannie Mae uses a 50% Short-Term Rental Factor.
The new short-term rental calculation is more conservative than the traditional 75% calculation for long-term rentals.
For applicable purchase transactions, documented monthly gross short-term rental income is multiplied by 50%.
PITIA is then subtracted.
Fannie Mae explains that the remaining 50% accounts for vacancy and maintenance. Even when positive, the resulting income may only offset PITIA. A negative amount must be included in DTI. This makes it important not to assume that projected Airbnb, VRBO, or other short-term booking revenue will qualify in the same way as a traditional 12-month lease.
When Does The New Fannie Mae Rental Income Guidelines Take Effect
Lenders are encouraged to implement these changes immediately but must do so for all loans with application dates on or after Jan. 1, 2024. For more information on this guideline change, Please see the Fannie Mae Selling Guide Announcement SEL-2023-09.
Setback For New Real Estate Investors
This guideline modification will impact prospective entrepreneurial investors interested in purchasing a primary residence with two to four units, provided they are not current homeowners or renters. The revised qualification process now requires individuals to qualify for the entire property without relying on potential future rental income. In contrast, the previous rule permitted the use of 75% of the fair market rents received to meet qualification criteria.
Other Options Versus Fannie Mae Rental Income Option For Real Estate Investors
The guidelines for mortgage products, including Fannie Mae Rental Income, are constantly evolving. Fannie Mae has recently undergone a significant change, a rarity in recent times. For those considering acquiring investment properties, we provide a range of loan programs customized to meet your specific needs.
Let’s Spotlight a Couple of Noteworthy Products:
Rental Income From Investment Properties Purchased Within 45 Days
Fannie Mae also created a special rule for investment properties purchased within 45 days of the application date for the subject mortgage. One- to four-unit investment properties can qualify under this rule. However, a lease agreement cannot be used to establish the rental income. Instead, qualifying market rent may be supported by an appraisal, Form 1007, when applicable, or qualifying market analysis documentation for multi-unit properties.
How the 45-Day Rule Calculates Rent
Gross market rent is multiplied by 75%, and PITIA is subtracted. If the result is positive, the income may only offset the related property’s PITIA. If the result is negative, the loss must be included in DTI. This prevents a recently acquired property with little operating history from generating unrestricted positive qualifying income before another mortgage transaction.
Fannie Mae Rental Income From an Accessory Dwelling Unit
Rental income from one existing ADU may be considered on an eligible one-unit primary residence. Fannie Mae limits ADU rental income to purchase and limited cash-out refinance transactions. Qualifying ADU rental income cannot exceed 30% of the borrower’s total qualifying income. An ADU scenario should not be confused with a duplex. A legal accessory unit is part of a one-unit property, while a duplex is a two-unit property. Property classification can affect the appraisal, occupancy, rental-income rules, and mortgage structure.
Can Rental Income From a Second Home Be Used?
Generally, no. Fannie Mae’s rental-income guidance states that rental income from a borrower’s second home cannot generally be used to qualify the borrower. A property intended mainly to generate rental income may need to be classified as an investment property rather than a second home.
Borrowers uncertain about the distinction can review Gustan Cho Associates’ guide to the difference between second homes and investment properties. (selling-guide.fanniemae.com)
Rental Property Owned Through an LLC, Partnership, or S Corporation
Rental income reported through a partnership or S corporation requires different underwriting treatment. When gross rents and related expenses are reported through the business, Fannie Mae requires that the rental income or loss be treated as self-employment income, regardless of the borrower’s ownership percentage or whether the borrower is personally obligated on the property’s mortgage.
When the property appears on the applicable federal business tax return, and the documentation clearly establishes that the business is responsible for the payments, the full PITIA may be excluded from the borrower’s DTI if the loan is current.
These files can become substantially more complicated than a property reported directly on Schedule E, so providing complete personal and business tax returns early can prevent underwriting delays.
Fannie Mae Reserve Requirements for Rental Properties
Rental-income qualification is only one part of investment-property underwriting. Fannie Mae’s reserve requirements vary according to occupancy, number of units, transaction type, and the number of financed properties owned by the borrower.
For Desktop Underwriter loan casefiles.
Fannie Mae Currently Lists Six Months of Reserves for:
- Two- to four-unit principal-residence transactions.
- Investment-property transactions.
- Certain cash-out refinances with DTI above 45%.
- Borrowers who own multiple financed properties may need additional reserves based on the aggregate unpaid principal balance of those properties.
- Reserves are funds remaining after closing, not the down payment.
- This distinction is important for real estate investors who may have enough money to close but not enough qualifying liquid assets remaining afterward.
How Rental Income Affects Debt-to-Income Ratio
Rental income can either improve or worsen a borrower’s debt-to-income ratio. A positive rental result may increase qualifying income or help offset a rental property’s mortgage expense, depending on the scenario. A rental loss normally increases monthly obligations. That is why underwriters do not simply look at the amount of rent received. They analyze the relationship between qualifying rent, PITIA, tax-return cash flow, occupancy, and rental-property experience. Borrowers who want to understand how the final numbers affect conventional qualification can also use Gustan Cho Associates’ Fannie Mae DTI guidelines and conventional mortgage calculator.
Common Fannie Mae Rental Income Mistakes
Rental-income files frequently run into problems when borrowers assume that ordinary landlord accounting and mortgage underwriting work the same way.
Common mistakes include using 100% of gross rent for mortgage qualification, assuming a newly signed lease is automatically acceptable, relying on projected short-term-rental revenue as though it were long-term rent, failing to disclose a rental-property loss,
using a family-member lease where the guidelines require an arm’s-length arrangement, failing to document the borrower’s current housing payment, and assuming a departing-residence lease can be used under the new 2026 policy.
Another common mistake is waiting until underwriting to calculate rental income. A difference of only a few hundred dollars per month can change DTI enough to affect eligibility.
What Documents Should Rental Property Borrowers Prepare?
The exact documentation depends on the property and transaction, but preparing the following items early can help:
- Most recent personal federal income tax returns, including Schedule E.
- Applicable business returns and Form 8825.
- Current executed leases.
- Recent evidence of rent payments.
- Security-deposit documentation for new leases.
- Current mortgage statements.
- Property-tax and homeowners-insurance information.
- HOA dues when applicable.
- Settlement statements showing when recently acquired properties were purchased.
- Property-management agreements.
- Documentation supporting major renovations or periods when a property was out of service.
- Evidence of the borrower’s current housing payment.
- Asset statements documenting required reserves.
Do not sign a new lease or restructure ownership solely because you assume it will improve your mortgage qualification. Have the complete scenario reviewed first.
What If Fannie Mae Rental Income Does Not Work for Your Scenario?
Fannie Mae financing is not the only option available to real estate investors. A borrower may have strong property cash flow but insufficient qualifying personal income, too little landlord history, extensive write-offs on tax returns, or a property structure that does not fit conventional underwriting. In those situations, a DSCR mortgage loan may be worth comparing with conventional financing.
DSCR loans are generally business-purpose investment-property loans that focus primarily on the property’s rental income and housing expense rather than qualifying the borrower through traditional personal-income calculations.
They have their own credit, equity, reserve, appraisal, prepayment, and investor requirements and should not be automatically assumed to be better or cheaper than a Fannie Mae loan. The correct financing structure depends entirely on the borrower and property profiles.
How Gustan Cho Associates Reviews Rental Income Before Pre-Approval
Rental-income qualification should ideally be completed before a borrower relies on the income to make an offer.
An Experienced Mortgage Professional Should Identify:
- Whether the property is the subject property or another property already owned.
- Primary-residence, second-home, or investment-property occupancy.
- Long-term versus short-term rental use.
- Current gross rent.
- Current PITIA.
- Whether the property appears on Schedule E.
- Length of rental-property management experience.
- Current housing payment.
- Number of financed properties.
- Available reserves.
- Whether a lease can legally be used under the applicable Fannie Mae scenario.
That review can determine whether rental income creates additional qualifying income, merely offsets a housing expense, or generates a rental loss that increases DTI. If a conventional mortgage does not fit, the borrower can then compare other rental-property financing options before entering into a contract.
Final Thoughts on Fannie Mae Rental Income Guidelines
Fannie Mae rental income guidelines are no longer well summarized by simply saying, “use 75% of the rent.” For traditional long-term rental properties, 75% remains an important calculation. But the final qualifying result depends on much more.
A borrower may need a documented current housing payment. 12 months of property management experience can determine whether positive cash flow qualifies as additional income.
Established rental properties may require a Schedule E analysis rather than a current lease. Newly executed leases now face additional validation requirements. Departing residences have a separate market-rent framework. Short-term rentals can be calculated using a 50% factor rather than 75%. The safest approach is to calculate the rental income before relying on it for mortgage approval.
Gustan Cho Associates works with homebuyers, homeowners, and real estate investors on conventional and alternative mortgage programs. Loan approval, available programs, rental-income treatment, rates, terms, and documentation requirements are subject to the borrower’s complete application, property review, underwriting, applicable agency guidelines, and investor requirements.
