Your Credit Score for a Home Loan: What Lenders Look At, and How to Improve It Before You Apply

Published 2026-11-08 · eLoanTree Blog

Of all the numbers in a home purchase, your credit score is the one buyers worry about most — and understand least. It is not a grade on your character, and it is not the only thing a lender looks at. But it affects whether you qualify, which loan types are open to you, and how much your loan costs every month.

1. What a credit score is

A credit score is a three-digit number, usually on the FICO scale of 300 to 850, that summarizes your credit history as recorded by the credit bureaus.

It is built from your payment history, how much of your available credit you are using, how long you have had credit, the mix of account types you hold, and how often you have applied for new credit. Payment history and the amount you owe carry the most weight in most scoring models.

You do not have one single score. Each bureau — Equifax, Experian, and TransUnion — keeps its own report, and there are different scoring models and versions. When you apply for a mortgage, the lender typically pulls all three bureaus. That is why checking only one free score from one source can give you a different number from the one a lender sees.

2. How lenders use your score

Lenders use your score in three ways. First, as a gate: each loan program has a minimum score. Second, as a pricing tool: within the range of people who qualify, a higher score generally means better pricing — a lower rate, lower mortgage insurance, or both.

Third, as one piece of a larger picture: your score is weighed together with your income, your debts, your down payment, and your savings. A strong score does not rescue a weak application on everything else, and a weaker score does not automatically disqualify you if the rest of your finances are strong.

3. The score ranges, and what they mean

Conventional loans. For most conventional loans that follow Fannie Mae and Freddie Mac guidelines, the commonly cited minimum is a 620 FICO score for fixed-rate loans (Fannie Mae Selling Guide, 2026; many individual lenders set their own higher cutoff, often 640 or 660).

A 620 score gets you through the door, not to the best pricing. Pricing generally improves as your score climbs, and scores of 740 and above are usually where the best conventional pricing sits. Below 680, expect higher costs than a borrower with the same loan and a higher score.

FHA loans. FHA loans are more forgiving. Under HUD Handbook 4000.1, a score of 580 or above qualifies for the standard 3.5% down payment, and a score of 500 to 579 qualifies with 10% down (HUD, 2026). Individual lenders often add their own overlays — for example, requiring 620 or above even for an FHA loan — so the program minimum is not always the minimum you will actually face.

These are general bands, not guarantees. A lender can approve or decline you at any score depending on the whole file, and a higher score never guarantees approval on its own.

4. What lenders see beyond the score

Your score is a summary; the report behind it is the detail. A lender will notice late payments, accounts in collections, a bankruptcy or foreclosure, high utilization, and several recently opened accounts. Two borrowers with the same score can look very different on paper.

5. How to improve your score before applying

There is no trick that raises a score overnight, and anyone who promises one is selling something. What works is slower and simpler.

1. Pay every bill on time, every time. Payment history is the largest factor in most scoring models. A single 30-day late payment can hurt, and a recent one hurts more than an old one. The best repair is a clean stretch of on-time payments after it.

2. Pay down credit card balances. The share of your credit limits you are using — called utilization — is the second big factor.

Using a small share of your limits looks better than using most of them, even if you pay in full each month, because the reported balance is what the bureaus see. Paying a card down from near its limit to well below it is often the fastest legitimate improvement available.

3. Do not open new accounts or close old ones right before applying. A new account lowers the average age of your accounts and adds an inquiry. Closing an old card can raise your utilization by removing its credit limit from the calculation, and it shortens your history. Leave your accounts as they are while you are shopping for a mortgage.

4. Check all three reports and dispute errors. Look for accounts that are not yours, balances that are wrong, and late payments you did not make. Correcting a genuine error can change your score, so do this months before you apply — disputes take time.

5. Do not take on new debt. A new car loan or a financed furniture purchase changes your debt-to-income ratio and can change your approval. If you are planning a large purchase, wait until after closing.

6. Be careful with "credit repair" offers. Paying a company to dispute accurate information will not remove it. The work that helps — paying on time, paying down balances, correcting real errors — is work you can do yourself for free.

6. When should you apply, and when should you wait?

If your score is just below a threshold that matters — for example, just below 620 for a conventional loan, or just below 580 for an FHA loan with 3.5% down — a few months of paying down cards and paying on time can be worth more than rushing in.

If your score is already comfortably above the threshold for the loan you want, waiting for a perfect score is usually not worth it: the pricing difference between, say, 750 and 780 is small, while the cost of waiting — rent, and possibly higher home prices — is real.
