Your credit score is the single biggest factor in what mortgage rate you get. And your rate determines everything — your monthly payment, how much interest you pay over 30 years, and ultimately how much house you can afford. A 50-point difference in your score can mean tens of thousands of dollars over the life of the loan.
So where do you actually need to be? And if you’re not there yet, how do you close the gap?
The Minimum Scores by Loan Type
Conventional loans: 620 minimum. But you won’t like the rate at 620. You’ll pay significantly more in interest and PMI compared to someone at 740+. Most lenders really want to see 680+ for decent terms.
FHA loans: 580 minimum with 3.5% down. If your score is 500-579, you can still qualify but you’ll need 10% down. FHA is more forgiving on credit but charges mortgage insurance for the entire life of the loan, which adds up.
VA loans: No official minimum from the VA, but most lenders set a floor around 620. VA loans don’t require PMI or a down payment, making them the best mortgage product available — if you qualify through military service.
USDA loans: 640 minimum for most lenders. Available for rural and some suburban areas with income limits.
Where You Want to Be
Here’s the real talk: 740+ gets you the best rates across virtually all lenders. That’s the magic number. Above 740, rate improvements are marginal. Below 740, every point costs you money.
The rate difference between a 640 and a 740 score on a $300,000 conventional loan can easily be 1 full percentage point — sometimes more. On a 30-year mortgage, that one point difference costs roughly $70,000 in total interest. Let that sink in. Your credit score isn’t just a number — it’s a price tag.
How to Boost Your Score Before Applying
If you’re 3-12 months away from buying, you have time to meaningfully improve your score. Here’s what actually moves the needle:
Pay down credit card balances. This is the fastest lever. Your credit utilization ratio (balances divided by credit limits) accounts for about 30% of your score. Getting below 30% utilization helps. Getting below 10% is even better. If you have a $10,000 credit limit and a $4,000 balance, paying it down to $1,000 can boost your score 30-50 points in a single billing cycle.
Don’t close old accounts. Length of credit history matters. That credit card you’ve had since college? Keep it open, even if you don’t use it. Closing it shortens your average account age and reduces your total available credit, both of which hurt your score.
Don’t open new accounts. Each new credit application generates a hard inquiry, which dings your score 5-10 points. More importantly, new accounts lower your average account age. In the 6 months before you apply for a mortgage, don’t open any new credit cards, auto loans, or other accounts.
Fix errors on your credit report. Pull your reports from all three bureaus at annualcreditreport.com (free, once per year). Look for accounts you don’t recognize, incorrect balances, and negative items that should have aged off (most negatives fall off after 7 years). Dispute any errors directly with the bureau — they have 30 days to investigate and correct.
Become an authorized user. If a family member has a credit card with a long history, low utilization, and perfect payment history, ask them to add you as an authorized user. Their positive history gets added to your credit report. You don’t even need to use the card. This can add 20-50 points, especially if your credit file is thin.
Set up autopay on everything. Payment history is 35% of your score — the single biggest factor. One 30-day late payment can drop your score 50-100 points. Autopay eliminates this risk entirely. Set it up for at least the minimum payment on every account.
What NOT to Do
Don’t pay for “credit repair” services. Most of them are scams that charge you hundreds of dollars to do things you can do yourself for free (disputing errors, negotiating with creditors). The legitimate credit-building strategies are all free.
Don’t make big financial moves right before or during the mortgage process. Don’t switch jobs, don’t move large sums between accounts, don’t co-sign for anyone, and don’t make any major purchases. Lenders pull your credit again right before closing — any changes can derail your loan.
The Bottom Line
Your credit score is the toll booth between you and the best mortgage rates. A few months of focused effort — paying down cards, fixing errors, avoiding new accounts — can save you tens of thousands of dollars over the life of your loan. If you’re planning to buy in the next year, check your score today. If it’s below 740, start working on it now. The money you save on your mortgage will dwarf whatever effort it takes to get there.
