Which Illinois home loan is right for you?
There is no single best mortgage. There is the one that fits your credit, your down payment, and your goals. Most Illinois buyers land on one of five paths, and the right choice usually comes down to your credit score and how much you have to put down. Here is the plain-English map.
| Loan | Min down | Min credit | Best for |
|---|---|---|---|
| VA | 0% | 580–620 | Veterans, active duty |
| USDA | 0% | 640 | Eligible rural areas |
| FHA | 3.5% | 580 | Lower credit, flexible ratios |
| Conventional | 3% | 620 | Stronger credit; drops PMI at 20% |
| Jumbo | 10%+ | 700+ | Above the conforming limit |
Don't have the down payment? There's help.
Illinois runs its help through IHDA, the state housing development authority. Its largest program, the new IHDAccess Home, gives 6% of the price up to $15,000 as a 0% deferred second, repaid only when you sell, refinance, or pay off. IHDA also offers a 5% Deferred second, a 4% Forgivable second that clears monthly over ten years, and a 10% Repayable second. All need a 640 credit score and a small borrower contribution of 1% or $1,000. Assistance layers onto your first mortgage, so you keep more cash at closing. First-time buyers in Illinois can see the full IHDA menu, the county income limits, and who qualifies.
What credit score do you need?
Lower than most people assume. FHA and VA open at 580, USDA at 640, conventional at 620, and jumbo usually wants 700+. A 600 score has real options today, and a focused 60–90 days can lift you a full tier and cut your rate. Your score sets your menu; it rarely closes the door.
What counts as a jumbo loan?
A jumbo loan is any mortgage above the conforming limit the FHFA sets each year. The 2026 baseline is $832,750, and in Illinois it applies in every one of the 102 counties, because no Illinois county qualifies as high-cost. Above that limit the loan cannot be sold to Fannie Mae or Freddie Mac, so it is underwritten to stricter standards, typically a larger down payment and a 700+ score. Most Illinois buyers stay under the limit; Chicago's North Shore and the higher end of the collar-county suburbs are where it comes up.
