Your credit score is one of the biggest factors in mortgage approval. It determines whether you'll qualify, what loan types you can use, and what rate you'll pay. Let's break down how it works and what you can do about it.
Your credit score is more than a number. It's the deciding factor in whether you'll qualify for a mortgage at all, and if you do qualify, it'll affect almost everything about your loan.
It determines if you'll qualify. Lenders have minimum credit score requirements for each loan type. If you're below the minimum, you won't get approved, period. There's no workaround.
It limits your loan type options. An FHA loan might accept a 580 credit score, but a conventional loan won't go below 620. That changes what down payment you'll need and what mortgage insurance you'll pay.
It controls your interest rate. A buyer with a 640 credit score and a buyer with a 720 score might get approved for the same loan amount, but they won't get the same rate. That 80-point difference can mean $100 to $200 more per month on a $350,000 loan. Over the life of the loan, that's tens of thousands of dollars.
It affects your monthly payment. Higher credit scores get better rates, which means lower monthly payments. It's that simple.

Your credit score isn't random. It's calculated based on five specific factors. Here's what matters most, and why.
Different loan types have different credit score requirements. Here's what you need to know.
You'll have credit checks at different stages. Here's what to expect and why.
Pre-qualification (soft pull): When you first talk to a lender, they might do a soft pull. This doesn't affect your credit score. It's just an estimate to see where you might stand.
Pre-approval (hard pull): Once you're ready to move forward, the lender runs a hard pull. This is a full credit check. It does show on your credit report and costs a few points temporarily.
During home search: No credit checks. You can look at as many homes as you want without your credit being touched.
Before closing (soft pull): A few days before closing, your lender might do another soft pull to make sure nothing changed. This doesn't hurt your score.
Important note: If you get multiple hard pulls for a mortgage within 45 days, they count as one inquiry. Don't be afraid to shop for rates. You won't be penalized as long as you do it within that window.
