Illinois Mortgage Calculator Guide
A mortgage estimate becomes more useful when every assumption has a job. For Illinois, the home-value benchmark anchors the purchase price, the city data supplies local tax context, and the assistance listings identify questions worth taking to an official program administrator. The current benchmark is $297,600, and this guide covers 50 city calculators. That sequence keeps the first estimate simple without hiding the local details that can change a real monthly payment.

Down-payment comparison
What 5%, 10%, and 20% down could look like in Illinois
These examples use the $297,600 statewide benchmark, a 6.75% 30-year fixed planning rate, the 2.12% midpoint property-tax assumption, and 0.35% annually for homeowners insurance. PMI is illustrated at 1% annually below 20% down.
| Down payment | Cash down | Loan amount | Principal & interest | Property tax | Insurance & PMI | Estimated monthly payment |
|---|---|---|---|---|---|---|
| 5% | $14,880 | $282,720 | $1,834 | $526 | $335 | $2,694 |
| 10% | $29,760 | $267,840 | $1,737 | $526 | $335 | $2,598 |
| 20% | $59,520 | $238,080 | $1,544 | $526 | $87 | $2,157 |
The examples do not include HOA dues, closing costs, discount points, lender fees, flood insurance, or property-specific insurance adjustments. Change the city calculator inputs before using a result for a budget.
Local variation
Why one Illinois estimate should not represent every city
The available city-page tax assumptions run from 1.48% for Chicago to 2.58% for Rockford, with a midpoint of 2.12% used in the statewide examples. That spread is a reminder to verify the parcel, assessment, exemptions, and taxing district before relying on a monthly number. Chicago and Lisle and Rockford are useful starting points for seeing how the planning assumptions vary inside Illinois.
These are effective-rate planning assumptions from 2024 public data, published in this system in 2026. Actual tax bills depend on assessed value, exemptions, levies, and the property's taxing districts.

The state-level research list currently contains 4 programs. IHDAccess Forgivable and IHDAccess Deferred are included as a place to begin, not as a promise of approval. Funding, income limits, first-time-buyer definitions, participating lenders, and eligible locations can change, so I would confirm the current rules before counting assistance as cash available at closing.

Open the relevant city calculator and verify the property-tax assumption against the parcel or local assessor.

Common questions
Planning a mortgage in Illinois
How much is an estimated mortgage payment in Illinois?
Using the current $297,600 statewide home-value benchmark, 20% down, a 6.75% 30-year planning rate, the 2.12% midpoint property-tax assumption, and a 0.35% insurance assumption, the estimated monthly payment is $2,157. Actual property, loan, tax, and insurance details can differ.
Does the Illinois mortgage estimate include property taxes?
Yes. The statewide examples use a 2.12% midpoint from the available city-page assumptions. A property-specific estimate should use the actual parcel, assessment, exemptions, and local taxing districts.
How much down payment should I compare in Illinois?
The page compares 5%, 10%, and 20% down. A smaller down payment reduces upfront cash but can increase the loan balance and may add mortgage insurance. Program and loan requirements vary.
Where should I verify Illinois homebuyer assistance?
Start with each linked official program source. Verify current funding, income limits, purchase-price limits, property rules, participating lenders, and first-time-buyer definitions before relying on assistance.
