Does Your Credit Score Give You the Best Mortgage Options?

Credit scores can affect mortgage eligibility, pricing, and the range of loan products available to a borrower, but a score should not be evaluated in isolation. Mortgage programs use different underwriting standards, lenders may impose additional requirements, and income, debt, assets, down payment, and other factors remain part of the decision. The useful objective is therefore not to reach an arbitrary credit score. It is to understand how your current credit profile affects your financing options and whether a specific improvement would produce a meaningful benefit.

Credit-scoring models vary, but information that can affect credit scores includes:

  • Payment history
  • Revolving balances relative to available credit
  • Length of credit history
  • Types of credit accounts
  • Recent applications and inquiries
  • Collections, charge-offs, and other derogatory information

ESTABLISHING CREDIT
Credit history develops as reported accounts establish a record of borrowing and repayment. Credit cards, installment loans, student loans, auto loans, and other obligations may contribute when reported to the credit bureaus.

For a consumer with limited credit history, a secured credit card may be one option. Authorized-user status on another person’s account can sometimes affect the user’s credit file when the issuer reports the account, although the impact depends on the account and scoring model.

Opening debt solely for the purpose of establishing credit should not be treated as a default strategy, particularly when a mortgage application is anticipated.

WHICH SCORE IS USED?
A consumer can have multiple credit scores because the underlying bureau data and scoring models may differ. Mortgage underwriting adds another layer because the applicable score can depend on the loan program, underwriting method, and number of borrowers.

For that reason, statements such as “the lender always uses the middle score” or “two borrowers’ scores are averaged” are incomplete. The lender should identify the scores applicable to the specific mortgage and explain how they affect eligibility and pricing.

CREDIT SCORE AND LOAN OPTIONS
No universal minimum score applies to every mortgage. Requirements differ among conventional and government-backed programs, underwriting systems, loan characteristics, and individual lenders.

VA, for example, does not impose its own minimum credit score, although VA lenders may establish additional credit standards. Other programs use their own criteria. Credit can also affect loan pricing, so meeting an eligibility threshold does not necessarily mean that two borrowers will receive identical terms.

The relevant comparison is the financing available at your current credit profile versus the financing that might be available if that profile materially improves.

IMPROVING CREDIT BEFORE A MORTGAGE APPLICATION
Review your credit reports for accuracy through AnnualCreditReport.com and dispute inaccurate information. Maintaining on-time payments and managing revolving balances responsibly may also support a stronger credit profile.

Once a mortgage application is approaching, however, avoid assuming that opening or closing an account, increasing a credit limit, transferring balances, paying off a particular loan, or financing a purchase will necessarily improve the mortgage outcome. Those actions can affect credit, available assets, and debt-to-income calculations differently. Have the lender model the effect before making a significant change.

Credit is one variable in a larger underwriting analysis that can include income, employment, debt, assets, down payment, loan-to-value, property costs, and the selected mortgage program.

For general information, NerdWallet offers additional suggestions for improving your credit score. For a home purchase, however, the more useful next step is to have a mortgage professional review your actual profile. I can recommend knowledgeable lenders who can compare the available scenarios and show you which changes would matter — and which ones probably wouldn’t.
