Credit Scores for a Mortgage (and How to Improve Yours)

Updated October 20, 2026 · Hyde Funding

Credit scores help lenders evaluate your ability to repay a mortgage. Stronger scores often open more options and smoother approvals, while lower scores may require additional steps or different programs.

Understanding Credit Scores in Mortgage Lending

Lenders review credit scores to gauge how reliably you have managed past debts. The score summarizes payment history, amounts owed, length of credit use, new credit, and credit mix.

Most loans use scores from the three major credit repositories. Lenders typically pull a merged report that includes scores from Equifax, Experian, and TransUnion.

How Lenders Select the Representative Score

Fannie Mae outlines a clear process for determining the representative credit score used for eligibility and pricing. For each borrower, select the lower score when two are available or the middle score when three are available. With multiple borrowers, the lowest of those individual scores becomes the loan-level representative score. Fannie Mae Selling Guide — B3-5.1-02, Determining the Credit Score for a Mortgage Loan

Freddie Mac follows a similar approach, requiring at least two scores per borrower and identifying an underwriting score and indicator score for manual or automated decisions. Freddie Mac Single-Family Seller/Servicer Guide — 5203.2: Credit Scores

Minimum Credit Score Requirements by Program

Requirements vary by loan type. Fannie Mae generally requires a minimum representative credit score of 620 for most loans delivered to the enterprise. Fannie Mae Selling Guide — B3-5.1-01, General Requirements for Credit Scores

FHA guidelines set different thresholds based on down payment. Borrowers with a minimum decision credit score at or above 580 qualify for maximum financing with a 3.5 percent down payment. Scores between 500 and 579 are limited to a maximum 90 percent loan-to-value ratio. Scores below 500 are not eligible. Borrowers without a credit score may still qualify through manual underwriting using nontraditional credit references. HUD FHA Handbook 4000.1 — II.A.2 Allowable Mortgage Parameters

VA and other government programs follow their own credit evaluation standards, which can differ from conventional and FHA rules.

What Happens When Scores Are Close or Missing

When one borrower lacks a score, the representative score is based on the remaining borrowers who have scores. Nontraditional credit histories can sometimes substitute when traditional scores are unavailable, though documentation requirements increase.

Frozen credit files at multiple repositories can prevent a loan from proceeding until the freezes are lifted.

Practical Steps to Strengthen Your Credit Profile

Improving your credit takes consistent effort over time. Focus on these areas:

Small, steady changes often produce noticeable results within several months.

Common Credit Report Issues and How to Address Them

Errors such as incorrect late payments or accounts that do not belong to you can lower scores. Gather documentation showing the correct information and submit disputes directly to the credit repositories. Significant material errors may allow a lender to consider manual underwriting in some cases.

Authorized user accounts can sometimes influence scores. Lenders evaluate whether those accounts reflect your own credit behavior.

Example Scenario

Consider a borrower with scores of 610, 595, and 620. The middle score of 610 would be selected for that individual. If a co-borrower has scores of 580, 590, and 575, the middle score of 580 is chosen. The loan representative score becomes the lower of 610 and 580.

This process helps lenders apply consistent standards across different credit profiles.

Timeline Considerations

Credit changes do not appear instantly. Payment history updates monthly, and disputes can take 30 days or longer to resolve. Planning ahead gives you time to see meaningful movement before submitting a mortgage application.

Frequently asked questions

What is the minimum credit score for an FHA loan?

FHA guidelines allow maximum financing with a score of 580 or higher. Scores from 500 to 579 require at least 10 percent down. Borrowers below 500 are generally not eligible, though those without scores may qualify through manual underwriting with nontraditional credit.

How do lenders pick which credit score to use?

For each borrower, lenders select the lower of two scores or the middle of three scores. With multiple borrowers, the lowest individual representative score becomes the loan-level score used for eligibility and pricing decisions.

Can I get a mortgage with no credit score?

Yes, in some cases. FHA allows manual underwriting with nontraditional credit references when no score exists. Fannie Mae and Freddie Mac also have provisions for borrowers without traditional credit histories, though documentation requirements are stricter.

How long does it take to improve a credit score?

Positive changes such as on-time payments and lower balances typically appear within one to two billing cycles. More significant improvements from dispute resolutions or debt reduction often require three to six months of consistent effort.

Does checking my credit hurt my score?

Soft inquiries for your own review do not affect scores. Hard inquiries from mortgage applications are expected and usually have limited impact when concentrated within a short shopping period.
