Mortgage Preapproval: How to Apply

How CFPB preapproval differs from prequalification, what lenders review, and why three letters are not a loan. Education, not an application.

Published: 2026-09-14

Key takeaways

  • The CFPB says prequalification and preapproval letters both state how much a lender is generally willing to lend, based on assumptions. Neither letter is a guaranteed loan offer.
  • Lenders use the two words differently. Some issue a prequalification from unverified information you report, and a preapproval only after they verify credit, income, assets, and debts.
  • The CFPB shopping guide says to ask at least three lenders for preapproval, and to do it in a short window so the credit pulls are more likely to count as one inquiry.
  • A preapproval does not commit you to that lender. The bureau says to wait for official Loan Estimates after you have a property before you pick a deal.

A preapproval letter is a lender's tentative statement that it is willing to lend up to a stated amount on stated assumptions. It helps a seller take an offer seriously. It is not a closed loan.

The CFPB is explicit: these letters "are not guaranteed loan offers." HomeMortgageOnline does not take applications or issue preapprovals.

What is the difference between prequalification and preapproval?

The CFPB says both letters specify how much the lender is willing to lend, up to a certain amount, based on certain assumptions. The words themselves are not standardized. "Don't worry about which word lenders use."

In practice, some shops call an unverified conversation a prequalification and reserve preapproval for a file with a credit pull and documents. Other shops use one label for both. Ask what was verified: credit, income, assets, debts, and whether the letter is a written commitment with an expiration date.

The bureau notes that some lenders will issue a written commitment letter valid for a period of time, subject to limited conditions. That is still not a closing. Conditions usually include an acceptable property, appraisal, title, and unchanged credit.

How do you apply for a preapproval?

The CFPB says lenders preapprove by looking at income, assets, debts, and credit. A typical document set matches what our first-time buyer pre-approval checklist already lists: recent pay stubs, W-2s, bank statements, tax returns if you are self-employed, photo ID, and permission for a credit pull.

You can start earlier than house hunting. The CFPB says an early letter can surface credit issues while there is still time to address them. Many people still wait until they are shopping in earnest because letters often expire in about 30 to 60 days and a credit pull is involved.

If a lender evaluates creditworthiness and then tells you that you do not qualify for the letter, the CFPB says the lender must provide an adverse action notice even if you never submitted a full application. That is a notice rule, not a finding about your file.

Why does the CFPB say to get three preapprovals?

The bureau's shopping guide says to ask at least three different lenders. Each shop looks at the same finances and estimates how much you can borrow and what interest you would likely pay. Doing the three pulls in a short period is the CFPB's way to limit extra credit impact.

A preapproval is a shopping tool, not a lender choice. The CFPB owning-a-home page says the letter "doesn't commit you to using that lender for your loan." Wait for official Loan Estimates that match the same property, loan type, and points before you compare APR and cash to close.

The letter amount is also not a budget. The CFPB says only you can decide how much you are comfortable paying each month. Run a planning range in the affordability calculator and the DTI explainer in Debt-to-Income Ratio: How Much House You Afford.

What usually happens after the letter?

Once a seller accepts an offer, the full application and property work begin: appraisal, title, insurance, and underwriting conditions. The CFPB requires a Loan Estimate within three business days of a complete application. That disclosure is the comparison document, not the preapproval letter.

Credit, income, or the property can still fail conditions. A preapproval that assumed a 20 percent down payment does not cover a 5 percent offer. Ask the lender to restate the letter if the down payment, loan type, or occupancy changes.

Rate note: a preapproval is not a rate lock and not a guaranteed APR. If you need the rate held, that is a separate lock agreement. See how a rate lock works.

Frequently asked questions

What is a mortgage preapproval?

The CFPB says a preapproval letter is a statement that a lender is tentatively willing to lend up to a certain amount on stated assumptions. It helps a seller take an offer seriously. It is not a guaranteed loan, not an approval of a specific house, and not a rate lock.

Is prequalification the same as preapproval?

Lenders use the words differently. The CFPB says some issue a prequalification from unverified information and a preapproval only after verification. Ignore the label and ask what was checked: credit, income, assets, and debts. Neither letter is a closed loan.

How many lenders should I ask for preapproval?

The CFPB shopping guide says to ask at least three, and to do it in a short window so the credit pulls are more likely to count as one inquiry. A preapproval does not lock you to that lender. Compare later Loan Estimates on the same property.

What documents do I need to apply for preapproval?

Lenders typically review income, assets, debts, and credit. That usually means pay stubs, W-2s, bank statements, tax returns if you are self-employed, ID, and a credit authorization. Exact lists vary. A complete application for a Loan Estimate comes after you have a property.

Does a preapproval guarantee I will get the loan?

No. The CFPB says these letters are not guaranteed offers. The property still has to appraise and clear title, and your credit and income have to stay in line with the assumptions. Conditions can fail after the letter is issued.
