Your credit score is one of the most critical factors in securing a mortgage. Not only does it determine whether you qualify for a loan, but it also dictates the interest rate you will pay, which can affect your monthly payment by hundreds of dollars.

Minimum Requirements by Loan Type
Different types of mortgages have different minimum credit score requirements. Here is a breakdown of the standard minimums:
| Loan Type | Minimum Credit Score | Notes |
|---|---|---|
| Conventional Loan | 620 | The most common type of mortgage. Better rates start at 740+. |
| FHA Loan | 580 (or 500) | Requires 3.5% down with a 580 score. 10% down required if score is 500-579. |
| VA Loan | No official minimum | For veterans and active military. Most lenders prefer 620+. |
| USDA Loan | 640 | For rural and suburban homebuyers meeting income limits. |
How Your Score Affects Your Interest Rate
Meeting the minimum score gets your foot in the door, but it doesn't get you the best deal. Lenders use risk-based pricing, meaning borrowers with lower credit scores are considered higher risk and are charged higher interest rates to compensate.
For a conventional loan, the best interest rates are typically reserved for borrowers with a credit score of 740 or higher (sometimes 760+ depending on the market).
The Cost of a Lower Score
Consider a $300,000 30-year fixed mortgage:
- Score 760+ (7.0% rate): Monthly payment is ~$1,995. Total interest: $418,000.
- Score 640 (8.0% rate): Monthly payment is ~$2,201. Total interest: $492,000.
That lower credit score costs an extra $206 per month and over $74,000 in additional interest over the life of the loan.
Ways to Improve Your Score Before Buying
If your score is on the borderline, taking 6-12 months to improve it before applying can save you massive amounts of money. Common strategies include:
- Pay down credit card balances: Lowering your credit utilization ratio (how much debt you have vs how much credit is available to you) is the fastest way to boost your score. Keep utilization below 30%, ideally below 10%.
- Check for errors: Pull your free credit reports from the three major bureaus (Equifax, Experian, TransUnion) and dispute any inaccurate negative marks.
- Never miss a payment: Payment history makes up 35% of your FICO score. One missed payment can drop your score by dozens of points.
- Don't open or close new accounts: Opening new credit cards causes hard inquiries, while closing old accounts reduces your average age of credit. Avoid both in the months leading up to a mortgage application.
Conclusion
While you can buy a house with a credit score in the high 500s or low 600s, striving for a score of 740 or above will unlock the best interest rates and lowest monthly payments. Always check your credit report months in advance so you have time to correct issues before applying for pre-approval.
