Illinois
An active mortgage market with solid lender competition. Regional banks and credit unions often offer competitive rates alongside national lenders.
What This Rate Means for You
A 760–779 credit score puts you in the strongest pricing bracket. At 6.375%, a $400,000 loan carries a principal and interest payment of $2,495/month. Borrowers in this tier are well-positioned to negotiate — lenders compete for low-risk profiles.
With 15% down, PMI will apply until you reach 20% equity. PMI typically costs 0.5–1.5% of the loan amount annually. On a $400,000 loan that's $166–500/month on top of your principal and interest payment.
Illinois Housing Market Context
The median home price in Illinois is approximately $275K, with a typical loan size around $234K for a 15% down buyer. Illinois is an active mortgage market anchored by Chicago, where competition among national and regional lenders is strong — typical loan sizes range from $180,000 to $380,000.
State-level variation in mortgage rates does exist — lender concentration, local competition, and property tax structures all influence the total cost of homeownership. However, the Optimal Blue OBMMI rate used here is a national benchmark. Your actual rate from a specific lender in Illinois may be somewhat higher or lower depending on lender pricing, current market conditions, and your full application file.
What Drives This Rate
Credit Score: 760–779
Your 760–779 credit score puts you in the top pricing tier. Most lenders offer their best available rates at this level.
Down Payment: 15%
A 15% down payment puts you at 85% LTV. PMI is required until your equity reaches 20%, adding to your effective monthly cost. Lenders price higher-LTV loans at a slight premium to offset the additional risk.
Market Conditions: 2026
The base rate (6.123%) reflects current 2026 market conditions for a prime borrower (760+ credit, 20% down). Rate adjustments above this base reflect standard Fannie Mae/Freddie Mac loan-level price adjustments (LLPAs) for credit score and LTV.
Frequently Asked Questions
What mortgage rate should I expect with a 760–779 credit score and 15% down in Illinois?
Based on 2026 market data, the benchmark for a 760–779 credit score (Excellent) with 15% down in Illinois is 6.375% for a 30-year fixed conventional loan, derived from Optimal Blue OBMMI rate data. If a lender quotes significantly above this, shopping additional lenders is worthwhile.
Does a 760–779 credit score qualify for a conventional mortgage in Illinois?
Yes. Conventional loan programs (Fannie Mae/Freddie Mac) require a minimum 620 credit score. A 760–779 score qualifies you for conventional financing. Lenders may vary in their exact pricing within this tier, and a higher score within the range may result in slightly better offers.
Is my rate already competitive at 760–779 credit?
At 760–779, you're in the top OBMMI pricing tier. The benchmark of 6.375% reflects the best available market pricing. If a lender quotes more than 0.25% above this, that warrants a second opinion. Your leverage is high — lenders want low-risk borrowers.
Would putting 20% down meaningfully change my rate?
Increasing from 15% to 20% does two things: eliminates PMI (saving $100–300/month typically) and may reduce your rate by 0.125–0.25% by crossing an LTV tier. On a $400,000 loan the combined monthly saving can exceed $200. If you're close to 20% down, it's worth calculating whether waiting to save more is the right move.
How many lenders should I compare in Illinois?
In Illinois, mortgage competition is strong — dozens of lenders actively compete for borrowers. Rate spreads between lenders for the same profile frequently exceed 0.375%. Getting 3–4 Loan Estimates (not just pre-qualification quotes) is standard practice and takes less than a week. Each application within a 45-day window counts as one credit inquiry.
How to Know If Your Lender’s Rate Is Fair
The benchmark above is your reference point — it represents the market rate for your exact profile based on actual locked loan data from Optimal Blue. If a lender quotes you more than 0.25% above this benchmark, that gap warrants a second opinion. Lender pricing spreads for the same borrower profile routinely exceed 0.375%, which on a $400,000 loan represents over $75/month or $27,000 over the life of the loan.
