The minimum score to qualify for a mortgage and the score that gets you the best rate are very different numbers. Here is what credit score thresholds actually mean for St. Louis buyers in 2026 -- and what improving your score before you apply is actually worth in dollars.
These are the floor scores -- the minimum needed to qualify. Qualifying at the minimum does not mean you will get the best rate or the most favorable terms.
| Loan Type | Minimum Score | Notes |
|---|---|---|
| FHA | 580 (3.5% down) / 500 (10% down) | MIP for life of loan if <10% down |
| Conventional | 620 typical minimum | Better rates above 700; best rates above 740 |
| VA | No official minimum; lenders typically require 580-620 | Best option for eligible veterans -- zero down, no PMI |
| USDA | 640 typical minimum | Eligible rural and suburban areas only |
| Best conventional rates | 740+ | Lowest PMI, best rate pricing |
The gap between a qualifying score and a great score is not just cosmetic. On a $250,000 loan in 2026, the difference between a 660 and a 760 credit score can translate to approximately $80 to $160 more per month in payment -- roughly $30,000 to $60,000 in additional interest over 30 years.
That means three to six months of focused credit improvement before you apply can be worth more than any other financial move you make in this process. This is not an abstract observation -- I tell every buyer who is close to a threshold to take the time to get over it before we start seriously touring.
The single largest factor. One 30-day late payment can drop your score by 60 to 110 points depending on your starting score. If you have late payments in your history, the impact diminishes over time -- a late payment from three years ago matters less than one from six months ago. Make every payment on time, every month, starting now.
The ratio of your current balances to your credit limits. Utilization above 30% on any card -- and above 10% for optimal scoring -- hurts your score. If you have a card with a $5,000 limit and a $3,500 balance, that is 70% utilization and it is dragging your score down significantly. Paying it to $1,500 moves you to 30% and produces a meaningful score improvement within 30 to 60 days.
The average age of your credit accounts. Do not close old accounts -- even ones you do not use -- before buying a home. Closing an old account reduces your average credit age and can lower your score.
Each new credit application triggers a hard inquiry that can lower your score. Do not open new credit cards, finance furniture, buy a car, or apply for any other credit between pre-approval and closing on your home.
Pull your free reports from all three bureaus at AnnualCreditReport.com before you apply for pre-approval. Errors on credit reports are more common than most people expect. A collection account that is not yours, a payment incorrectly reported as late, or an account with a wrong balance can all be disputed and corrected -- and the correction can improve your score within 30 to 45 days of the dispute being resolved.
Checking your own credit is a soft inquiry and does not affect your score. Do this at least 60 days before you plan to apply for pre-approval so you have time to dispute and correct any errors you find.

FHA loans accept scores as low as 580. Conventional loans typically require 620. VA loans have no official minimum but most lenders require 580 to 620. However, a score of 700 or higher gives you meaningfully better interest rates -- the minimum to qualify is not the same as the score that costs you the least.
How much does my credit score affect my mortgage rate?
On a $250,000 loan, the difference between a 660 and a 760 score can be $80 to $160 per month in payment -- roughly $30,000 to $60,000 over 30 years. Improving your score before applying is often the highest-return move a buyer can make.
How long does it take to improve my credit score before buying?
Meaningful improvement typically takes three to six months: pay down revolving balances below 30% of limits, make all payments on time, and avoid new credit applications. Disputing errors on your report can produce faster gains -- some buyers see significant improvement in 60 to 90 days.
Does checking my own credit hurt my score?
No. Checking your own credit at AnnualCreditReport.com is a soft inquiry and has no impact on your score. Pull all three bureaus before your lender does so you can identify and dispute any errors in advance.
