How to Buy a Home in Illinois: Step-by-Step Guide for 2026
Buying a home in Illinois follows a process that differs from most other states in several important ways. Illinois requires attorney representation at closing — not optional, not a suggestion, a genuine requirement that adds cost but also adds a layer of protection for buyers. The state uses a “title theory” system with title insurance instead of the escrow system common in western states. And the attorney review period — typically 5 business days after contract signing — gives both parties a window to modify or terminate the deal that doesn’t exist in many other states.
These Illinois-specific elements mean out-of-state transplants and first-time buyers need to understand the process before starting their home search. Here’s the step-by-step guide, from pre-approval through closing day.
Step 1: Get Pre-Approved for a Mortgage
Before you look at a single home, get pre-approved (not just pre-qualified) by a mortgage lender. Use our amortization schedule calculator for detailed numbers. Pre-approval involves a hard credit pull, income verification, and a written commitment for a specific loan amount. In competitive Illinois markets — particularly Chicago’s North Side and the western suburbs — sellers strongly prefer offers from pre-approved buyers.
| Loan Type | Min. Down Payment | Credit Score Minimum | Best For |
|---|---|---|---|
| Conventional | 3–5% | 620+ | Buyers with good credit and savings |
| FHA | 3.5% | 580+ | First-time buyers, lower credit scores |
| VA | 0% | No minimum (lender sets) | Veterans and active military |
| USDA | 0% | 640+ | Rural Illinois (many areas qualify) |
| IHDA Access Mortgage | Varies (DPA available) | 640+ | First-time IL buyers (income limits) |
Use our affordability calculator to determine how much you can spend, and our mortgage calculator to estimate monthly payments. Illinois’ high property taxes significantly affect your debt-to-income ratio and reduce your purchasing power compared to lower-tax states — factor this in from the start.
Step 2: Hire a Buyer’s Agent
As of 2024, buyers must sign a buyer representation agreement before their agent can show homes (per NAR settlement rules). This agreement specifies the agent’s commission rate and services. Most buyer’s agents in Illinois charge 2.5–3% of the purchase price, often paid by the seller through cooperative compensation.
Choose an agent with experience in your target area. Chicago has 77 community areas, each with distinct market dynamics. Suburban markets vary by school district and township. An agent who knows your target neighborhoods saves you money and time. Read our guides to the best agents in Chicago and best agents in Naperville.
Step 3: Search for Homes and Make an Offer
Once you find a home, your agent helps you prepare an offer. Illinois purchase contracts typically include:
- Purchase price and earnest money: Earnest money in Illinois is usually 1–3% of the purchase price, deposited within 2–3 business days of acceptance.
- Financing contingency: Protects you if your mortgage isn’t approved.
- Inspection contingency: Gives you 5–10 days (negotiable) to have the property inspected.
- Attorney review clause: Standard in Illinois contracts — 5 business days for both attorneys to review and modify terms.
- Closing date: Typically 30–45 days from contract acceptance.
Step 4: Attorney Review Period (5 Business Days)
This is the most Illinois-specific part of the process. After the contract is signed by both parties, a 5-business-day clock starts. During this period, either the buyer’s or seller’s attorney can:
- Request modifications to the contract terms
- Add conditions (inspection requirements, repair requests, financing terms)
- Terminate the contract entirely, for any reason
The attorney review period is not just a formality — it’s your best protection against a bad deal. Your real estate attorney reviews the contract for unfavorable terms, checks for issues with the property’s legal description, and ensures the contingencies protect your interests. Attorney fees for this service run $500–$1,500 and are well worth the cost.
Once both attorneys approve (or the 5 days expire without objection), the contract becomes binding.
Step 5: Home Inspection
Schedule your inspection within the first 2–3 days of the contract (or during attorney review, if your attorney recommends it). Illinois home inspectors must be state-licensed under the Home Inspector License Act.
Essential inspections for Illinois homes:
- General home inspection: $300–$550 (required)
- Radon testing: $100–$175 (strongly recommended — Illinois is EPA Zone 1)
- Sewer scope: $150–$250 (strongly recommended for pre-1980 homes with clay laterals)
- Termite/WDO inspection: $75–$150 (recommended in central and southern IL)
Your attorney uses the inspection report to negotiate repairs, credits, or price reductions. In Illinois, the buyer typically requests specific repairs or a credit toward closing costs, and the seller can accept, counter, or reject.
Step 6: Appraisal and Underwriting
Your lender orders an appraisal to confirm the property’s value supports the loan amount. If the appraisal comes in below the purchase price, you have three options: renegotiate the price, make up the difference in additional down payment, or use your financing contingency to exit.
During underwriting, the lender verifies everything — income, employment, assets, credit, title search. Keep your financial situation stable during this period: don’t change jobs, don’t take on new debt, don’t make large purchases, and don’t move money between accounts without documentation.
Step 7: Title Search and Insurance
Illinois uses title insurance (not the escrow/deed-of-trust system used in western states). The title company searches public records for liens, judgments, easements, and ownership disputes. Title insurance protects you (and your lender) against defects in the title that weren’t discovered during the search.
| Title Cost Component | Typical Cost | Who Pays (Typical) |
|---|---|---|
| Title Search | $300–$500 | Buyer |
| Lender’s Title Insurance | $400–$800 | Buyer (required by lender) |
| Owner’s Title Insurance | $500–$1,200 | Seller (customary in most of IL) |
In most of Illinois, the seller customarily pays for the owner’s title insurance policy. In some Chicago-area transactions, this is negotiable. Your attorney should clarify who pays what.
Step 8: Final Walk-Through
Schedule a final walk-through 24–48 hours before closing. Verify that agreed-upon repairs have been completed, the property is in the same condition as when you made your offer, and all fixtures and appliances included in the contract are present. This is not an inspection — it’s a confirmation.
Step 9: Closing Day
Illinois closings happen at a title company or attorney’s office. Both the buyer’s and seller’s attorneys attend (or their representatives). Here’s what you’ll sign and pay:
| Closing Cost Item | Typical Cost (Buyer) | Notes |
|---|---|---|
| Attorney Fees | $500–$1,500 | Required in IL |
| Title Insurance (Lender’s) | $400–$800 | Required by lender |
| Transfer Tax Stamps | Varies by municipality | See breakdown below |
| Recording Fees | $100–$300 | County recorder’s office |
| Prorated Property Taxes | Varies | Tax proration per contract |
| Loan Origination Fee | 0.5–1% of loan | From lender |
| Prepaid Items (Insurance, Tax Escrow) | $2,000–$5,000 | Lender escrow requirements |
Use our closing cost calculator to estimate your total out-of-pocket expenses at closing.
Illinois Transfer Tax Stamps
Illinois charges transfer taxes at closing that add up quickly, especially in Chicago:
- State: $0.50 per $500 of sale price (0.10%)
- County: $0.25 per $500 (0.05%)
- Chicago: Additional $3.75 per $500 (0.75%) — buyer pays $7.50 per $500 total
- Some suburbs: Additional municipal stamps (varies)
On a $350,000 home in Chicago, transfer taxes total approximately $5,250 — a significant closing cost. Outside Chicago, total transfer taxes on the same home are about $525. Read our full guide to Illinois transfer taxes.
IHDA Programs for First-Time Buyers
The Illinois Housing Development Authority (IHDA) offers several programs that help first-time buyers with down payments and closing costs. These programs are available through participating lenders statewide:
| Program | Benefit | Income Limit | Key Requirements |
|---|---|---|---|
| IHDAccess Forgivable | $6,000 forgivable after 10 years (no repayment if you stay) | $99,000 (varies by county) | 640+ credit, first-time buyer, homebuyer counseling |
| IHDAccess Deferred | $7,500 deferred — repaid at sale, refi, or payoff | $99,000 | 640+ credit, first-time buyer |
| IHDAccess Repayable | $10,000 second mortgage at low fixed rate | $99,000 | 640+ credit, first-time buyer, 10-year repayment |
| Opening Doors | Reduced mortgage rate | Varies | For buyers in targeted areas or qualifying professions (teachers, first responders, veterans) |
The IHDAccess Forgivable program is the best deal if you plan to stay at least 10 years — you receive $6,000 toward your down payment or closing costs and owe nothing back after a decade. Combined with an FHA loan (3.5% down), a buyer purchasing a $300,000 home could cover most of their down payment through IHDA assistance.

After Closing — Don’t Forget These
- Apply for the homeowner exemption. This reduces your property tax bill by $500–$2,000+ per year depending on your county and tax rate. It’s not automatic — you must apply. Read our guide on getting the homeowner exemption.
- Change your voter registration and driver’s license. Illinois requires you to update within 90 days of moving.
- Set up utility accounts. ComEd (electric), Nicor/Peoples Gas (gas), and municipal water/sewer all need to be transferred.
- Review your property tax bill. Your first bill will arrive about 6 months after closing. Verify the assessed value and exemption status.
Illinois-Specific Costs That Surprise Buyers
Beyond standard closing costs and mortgage payments, several Illinois-specific expenses catch first-time buyers off guard:
| Surprise Cost | Amount | When It Hits |
|---|---|---|
| Tax proration gap | $2,000–$6,000 | First year — taxes paid in arrears, so you owe for seller’s occupancy period at closing |
| Homeowner exemption delay | $500–$2,000 | First year — exemption may not apply until second tax bill |
| Sewer lateral repair | $3,000–$12,000 | Within first 2 years (if pre-1970 home with clay pipes) |
| Radon mitigation | $800–$1,500 | At closing or shortly after (1 in 3 IL homes fails radon test) |
| Chicago transfer stamps | $5,000–$8,000 | At closing (Chicago only — the buyer pays a significant stamp tax) |
| Property tax increase (Year 2+) | $500–$2,000/year | Annual — rates increase 2–4% per year on average |
The tax proration gap is particularly confusing. Illinois property taxes are paid in arrears — you’re always paying for the previous year. At closing, the seller credits you their share of the current year’s taxes, but the actual bill doesn’t arrive for months. Meanwhile, your lender may underestimate the escrow because the homeowner exemption hasn’t been applied yet, leading to an escrow shortage and a higher monthly payment in year two. Plan for this by building a $3,000–$5,000 cash cushion beyond your closing costs. Use our down payment calculator to plan your savings timeline.

Frequently Asked Questions
Do I need a lawyer to buy a house in Illinois?
Yes. Illinois requires attorney representation for real estate closings. Both the buyer and seller should have their own attorney. The buyer’s attorney typically charges $500–$1,500 for the full closing process, including contract review during the attorney review period, title work coordination, and closing attendance.
What is the attorney review period in Illinois?
A 5-business-day window after contract signing during which either party’s attorney can modify terms, add conditions, or terminate the contract. This is standard in Illinois real estate contracts and provides critical buyer protection. Once both attorneys approve, the contract becomes binding.
How much are closing costs in Illinois?
Buyer closing costs in Illinois typically run 2–5% of the purchase price, depending on location. Chicago buyers pay more due to the city’s transfer tax ($3.75 per $500). On a $350,000 home, expect $7,000–$17,500 in total closing costs. Use our closing cost calculator for a personalized estimate.
What is the homeowner exemption in Illinois?
The general homeowner exemption reduces your equalized assessed value by $10,000 (Cook County) or $6,000 (all other counties). On a typical Illinois property, this saves $500–$2,000 per year in taxes. You must own and occupy the property as your primary residence and apply through your county assessor’s office.
How long does it take to close on a house in Illinois?
The typical timeline is 30–45 days from contract signing to closing. The attorney review period (5 business days), inspection period (5–10 days), and appraisal/underwriting (2–3 weeks) run partially in parallel. Cash transactions can close in as little as 10–14 days. Delays usually come from underwriting issues, title problems, or appraisal concerns.
What is unique about buying a home in Illinois compared to other states?
Three things set Illinois apart: mandatory attorney representation at closing (most states don’t require this), the 5-business-day attorney review period (which gives buyers an exit ramp after signing the contract), and the high property taxes that significantly reduce purchasing power compared to lower-tax states. Use our property tax calculator for detailed numbers. Chicago adds its own layer of complexity with transfer tax stamps ($7.50 per $500 of sale price on the buyer side) that can add $5,000–$8,000 to closing costs. On the positive side, the attorney review period is a powerful buyer protection that doesn’t exist in most states — your attorney can terminate the deal within those 5 days for any reason, giving you flexibility that contract-only states don’t offer.
