Why Preparing for a Mortgage in Illinois Is Different

The mortgage process in Illinois has some unique steps compared to other states:

1. Illinois is not a community property state.

Your spouse’s credit or debt isn’t considered unless they are on the loan. In states like Texas or California, both spouses’ debts count — but not in Illinois.

2. Real estate attorneys are required.

In Illinois, it is common for both buyers and sellers to have real estate attorneys manage the closing process rather than relying on the title company. This ensures your contract and title work are reviewed by a legal professional.

3. Property taxes are paid in arrears.

Illinois homeowners pay property taxes for the previous year at closing. Homebuyers can often use property tax prorations from the seller toward their down payment or closing costs — a major advantage unique to Illinois.

Step 1: Get Prequalified Before House Hunting

The first step in preparing for a mortgage in Illinois is to get prequalified or pre-approved by a lender.

At Gustan Cho Associates, we believe the pre-approval stage is where most buyers either set themselves up for success — or get into trouble.

Unfortunately, over 80% of our clients come to us after being denied or delayed by another lender because they weren’t properly qualified upfront. Many banks issue “pre-approvals” without thoroughly verifying income, credit, or assets.

A solid pre-approval should include:

Full review of income and assets
Tri-merge credit report
AUS (Automated Underwriting System) findings
Debt-to-income ratio calculations
Verification of funds for the down payment and closing

Pro Tip: Don’t just shop for the lowest rate — shop for a lender with experience, transparency, and no overlays. At GCA, we issue fully underwritten TBD pre-approvals that are strong enough to close fast.

Step 2: Organize Your Documents Early

Being organized is key to preparing for a mortgage in Illinois. You’ll receive a document request list once your loan officer reviews your credit and AUS results. The faster you provide these items, the faster your file moves.

Here’s a checklist to help you get mortgage-ready:

Mortgage Readiness Checklist (Illinois)

2 years of W-2s and federal tax returns
30 days of most recent pay stubs
60 days of bank statements
Driver’s license and Social Security card
Divorce decree (if applicable)
Bankruptcy or foreclosure paperwork (if applicable)
Child support or alimony documentation
Letter of explanation for any credit issues or gaps in employment

Tip: Always include all pages of documents — even the blank ones. Missing pages cause delays and underwriting conditions.

Step 3: Understand the Illinois Mortgage Process

Preparing for a mortgage in Illinois starts with a key step: submitting your documents. After you’ve pulled together all the needed paperwork, a mortgage processor will review your file. This person checks your documents to ensure they are complete and accurate before sending them off to underwriting.

A solid and organized file is super important when preparing for a mortgage. A well-structured submission speeds things up and helps avoid delays. If your application is incomplete, it could lead to extra requests or hold-ups from the underwriter, pushing back your closing date. So, it’s important to pay attention to the details and ensure your documentation is spot on.

At Gustan Cho Associates, we understand that preparing for a mortgage in Illinois can be tricky, which is why our processors focus on sending only complete files. By being detail-oriented, we help make the underwriting process smoother and faster. Our goal is to make sure you get your mortgage approval efficiently and reach closing without unnecessary bumps in the road.

Step 4: Write Letters of Explanation (LOEs)

Don’t panic about credit issues, late payments, or past bankruptcies. You can still qualify for a mortgage in Illinois — even with:

Collections and charge-offs
Past bankruptcy or foreclosure
Late payments or judgments

You’ll need to provide a Letter of Explanation (LOE) that clarifies what happened and how the situation has been resolved. Your loan officer will help you write this professionally and clearly.

Example:

“I had late payments in 2022 due to temporary unemployment. Since then, I’ve returned to full-time work and maintained on-time payments for over 12 months.”

Step 5: Mortgage Underwriting and Conditional Approval

After the processor submits your file, an underwriter reviews it for accuracy and compliance with FHA, VA, USDA, or conventional guidelines.

If everything checks out, you’ll receive a conditional loan approval — meaning the underwriter needs a few final items before issuing your Clear to Close (CTC).

Common Conditions Include:

Updated pay stubs or bank statements
Verification of employment (VOE)
Appraisal updates or contract extensions
Proof of funds to close

Once these are cleared, your lender will issue the Clear to Close — the final green light before signing.

Step 6: Cash to Close and Property Tax Prorations in Illinois

One of the most significant differences when preparing for a mortgage in Illinois is how property tax credits work.

Since property taxes are paid in arrears, the seller typically gives the buyer a credit for last year’s taxes at closing. That credit can reduce the cash you need to bring to closing.

Example Scenario:

Home purchase price: $100,000
FHA down payment (3.5%): $3,500
Property taxes: $3,000
Seller tax credit: $3,000

Result: Buyer only needs $500 cash to close!

Keep in mind: Seller concessions can only be used for closing costs, not for the down payment.

Case Study: First-Time Buyer in Naperville, IL

Buyer: Maria L., first-time homebuyer

Credit Score: 620

Loan Type: FHA Loan

Challenge: Recently paid off collections and had limited savings

Solution:

Maria contacted Gustan Cho Associates after another lender denied her application. Our team ran her file through the AUS and issued a TBD pre-approval. We helped her use the seller’s property tax prorations to cover most of her down payment and guided her through document prep.

Result:

Maria closed on her new home in just 21 days — stress-free and with minimal cash to close.

Step 7: Final Walkthrough, Closing, and Attorney Coordination

In Illinois, your real estate attorney will review your final loan documents and closing disclosure (CD). Attorneys handle the title and deed transfer, ensuring your closing is legally sound.

Before closing:

Review your final loan terms
Confirm cash-to-close amount
Schedule your final walkthrough
Verify property condition matches the purchase agreement

Once everything checks out, you’ll attend closing with your attorney, sign the documents, and receive your keys!
