Mortgage Pre-Approval Requirements in 2026: What Homebuyers Need to Know

Mortgage pre-approval is a lender’s preliminary estimate of how much you may be able to borrow. In 2026, lenders generally review your credit history, income, employment, debts, and savings. Knowing what they look at lets you prepare before you start house hunting.

Lenders look at five areas: credit history, income and employment, debt-to-income ratio (DTI), down payment, and assets. Minimums depend on the loan program, and lenders may set stricter standards than the program does.

Because no single credit score applies to every borrower, lenders review your score together with your payment history and balances. Plan for closing costs and reserves on top of the down payment.

Start your pre-approval

Lenders want to see that your income is sufficient and likely to continue. Salaried borrowers provide pay stubs and W-2 forms. Self-employed borrowers usually provide two years of tax returns, though Fannie Mae allows one year in limited cases. Bonus or commission income may count when it is documented, so keep records of how long you have received it.

Gather government-issued identification, recent pay stubs, W-2 forms or tax returns, bank statements, debt statements, and investment statements. Together they verify your identity, income, available funds, obligations, and assets. Having them organized before you apply helps the lender review your file without delays.

DTI is the share of your gross monthly income that goes toward qualifying debt payments.

DTI = Total monthly debt payments ÷ Gross monthly income × 100

For example, $3,200 in qualifying monthly debts on $8,000 of gross monthly income is a 40% DTI. That figure is illustrative, not a program limit. Fannie Mae’s limit is 36% for manually underwritten loans, up to 45% with stronger credit and reserves, and 50% for automated approvals. FHA manual underwriting starts at 43%, with higher ratios allowed when compensating factors apply. Because existing debts count toward your DTI, paying them down can affect how much you can borrow.

The CFPB notes that lenders use these terms differently. Some base pre-qualification on information you report and issue pre-approval only on verified information. Neither is a guaranteed loan offer. Ask each lender what its process includes before relying on either letter.

A mortgage pre-approval letter states that you may qualify to borrow up to a specified amount after a preliminary review. It may list an estimated loan amount, an expiration date, and conditions. Each lender sets how long the letter stays valid. If it expires, ask what updated documentation the lender needs before it issues a new one.

Lenders may check your credit when issuing a pre-approval, and a lender inquiry typically has a small negative effect on your score. Multiple mortgage credit checks within 45 days count as one inquiry, so comparing lenders within that window costs little. Checking your own credit does not affect your scores.

A mortgage pre-approval calculator estimates borrowing capacity and monthly payments from your income, debts, down payment, interest rate, and loan term. Treat the results as estimates, not lending decisions. Add property taxes, insurance, and any homeowners association fees to your monthly budget.

1. Review your income, savings, debts, and housing budget.
2. Check your credit reports and correct inaccuracies.
3. Gather identification, income documents, and bank statements.
4. Submit your application and authorize required credit checks.
5. Provide additional documentation when requested.
6. Review the letter’s loan amount, conditions, and expiration date.

After an accepted offer, underwriting verifies your finances and the property.
