The Home-Buying Process in Illinois, Step by Step (2026)

Buying a home in Illinois works a little differently than in many states — most notably, Illinois is an “attorney state,” so buyers and sellers each typically hire a real estate attorney, and the standard contract includes an attorney review and inspection period. If you’re moving here from elsewhere, that’s the biggest surprise. Here’s the whole process, start to finish, in plain terms.

This is a general educational overview, not legal or tax advice. Confirm specifics with a licensed Illinois real estate attorney and your lender.

Step 1: Get pre-approved

Before you shop, get a mortgage pre-approval (not just a pre-qualification) from a lender. It tells you your real budget, signals to sellers that you’re serious, and is effectively required to have an offer taken seriously in competitive western-suburb markets. Have your income, asset, and credit documentation ready.

Step 2: Decide where (and set your priorities)

In the western suburbs, the town you choose drives your schools, taxes, and commute for years — so this step matters as much as the house. Rank what matters most and narrow to a short list. (Start with our guide to moving to the western suburbs ›)

Step 3: Tour homes and make an offer

Once you’ve found the one, you submit a written offer (a contract). Beyond price, it specifies your earnest money, financing terms, proposed closing date, and contingencies (inspection, financing, sometimes appraisal). In Illinois, the widely used Multi-Board Residential Real Estate Contract is the standard form. Sellers may accept, reject, or counter.

Step 4: The attorney review & inspection period

This is the Illinois-specific part. After both sides sign, the contract typically opens a 5-business-day attorney review and inspection period during which:

• Each party’s attorney reviews and can propose modifications to the contract (or, in limited cases, disapprove it).
• You conduct your home inspection and can request repairs, a credit, or — if issues are serious — cancel.

This window is your real protection. Use a qualified inspector, read the report closely, and lean on your attorney. The contract isn’t truly “firm” until this period closes with both sides in agreement.

Step 5: Earnest money

Earnest money is your good-faith deposit, commonly 1%–5% of the purchase price (higher in competitive situations), held in escrow and applied to your down payment/closing costs at closing. If you cancel within your contingencies, it’s generally refundable; if you walk without cause, you can lose it.

Step 6: Mortgage, appraisal & title

With the contract firm, your lender orders an appraisal (the home must appraise at or near the price for the loan) and processes underwriting. Meanwhile, a title search confirms clear ownership and a title insurance policy is prepared. Stay responsive to your lender’s document requests — this stage is where delays happen.

Step 7: Final walkthrough & closing

Just before closing you do a final walkthrough to confirm the home’s condition and that agreed repairs were made. At closing, you (and typically your attorney) sign the loan and transfer documents, funds are exchanged, and you get the keys. In Illinois, the whole process commonly runs ~30–45 days from accepted contract to closing.

Illinois closing costs & the tax proration credit

Two Illinois specifics buyers should budget for and understand:

• Transfer taxes. Illinois charges a state transfer tax of $0.50 per $500 of price (0.1%) and a county tax of $0.25 per $500 (0.05%) — usually paid by the seller. Some municipalities add their own transfer tax (rules and who pays vary by town), so confirm locally.
• The property tax proration credit. Illinois pays property taxes in arrears (you pay this year’s taxes next year). So at closing, the seller typically credits you for the taxes that accrued during their ownership but aren’t yet billed. This is a meaningful, often-misunderstood line on a western-suburb closing, where tax bills are large — your attorney will calculate it.

Other typical buyer costs: lender fees, appraisal, attorney fee (Illinois attorney fees for a purchase are usually modest and flat), title charges, and prepaid escrows (insurance and taxes).

Frequently asked questions

Do I need a real estate attorney to buy a house in Illinois?

In practice, yes. Illinois is an “attorney state” — buyers and sellers each typically retain a real estate attorney, and the standard contract includes an attorney review period. Your attorney reviews the contract, handles title and the tax proration, and represents you at closing. Attorney fees for a purchase are usually modest and flat.

What is the attorney review period in Illinois?

A window — commonly five business days after both sides sign — during which each party’s attorney can review and propose changes to the contract, and the buyer conducts the home inspection and can request repairs, a credit, or cancellation. The deal isn’t truly firm until this period closes in agreement.

How much earnest money do I need in Illinois?

Commonly 1%–5% of the purchase price, higher in competitive situations. It’s held in escrow and applied to your down payment and closing costs at closing. It’s generally refundable if you cancel within your contingencies, but can be at risk if you walk without cause.

How long does it take to close on a house in Illinois?

Commonly about 30 to 45 days from an accepted, firm contract to closing, plus the ~5-business-day attorney review/inspection period at the start. Cash purchases can be faster; financing, appraisal, and title work set the pace for most buyers.

What is a property tax proration credit?

Because Illinois pays property taxes in arrears, the seller typically credits the buyer at closing for the taxes that accrued during the seller’s ownership but aren’t yet billed. On western-suburb homes, where tax bills are large, this is a significant line item — your attorney calculates it.
