Prequalification vs. preapproval: what's the difference?
Written for Shawn Way MortgageUpdated Sources checked
The short answer
The CFPB notes that lenders use prequalification and preapproval differently; ask what the lender actually verified. Often a prequalification is based on what you report without checking it, while a preapproval follows a credit check and a review of your income, assets and debts. Neither is a guaranteed loan offer. Ask each lender what it verified and when the letter expires.

How do lenders use prequalification and preapproval?
The CFPB says lenders use the terms prequalification and preapproval differently. Both letters state how much a lender is generally willing to lend you, based on certain assumptions. Neither is a guaranteed loan offer.
Some lenders base a prequalification on information you report without checking it, and issue a preapproval only after they verify it. Some lenders offer only one of the two. Because practices vary so much, the label on the letter tells you less than the process behind it.
What does a lender check for a preapproval?
The CFPB's preapproval guide says lenders look at four things:
- Income: pay stubs, W-2s, tax returns or other proof.
- Assets: bank and investment statements that show your down payment and reserves.
- Debts: car loans, student loans, credit cards and other monthly obligations.
- Credit record: your credit report and score.
A prequalification may rely on your own estimates of these numbers. The more a lender verifies up front, the more weight a seller may give the letter.
Will a preapproval hurt my credit?
Lenders typically check your credit before issuing a preapproval letter, and the CFPB says lenders may check it for either type of letter. A mortgage credit check is recorded as an inquiry on your credit report.
Shopping with several lenders does not have to multiply the effect. The CFPB says that within a 45-day window, multiple credit checks from mortgage lenders are recorded as a single inquiry. Its Your Home Loan Toolkit notes that the shopping window depends on the scoring model and is generally between 14 and 45 days. To be safe, keep your rate shopping within 14 days.
Because of the credit check, the CFPB suggests waiting to get preapproved until you are ready to shop seriously. Getting preapproved early, though, can help you find and fix credit report errors.
How long does a preapproval letter last?
The CFPB says a preapproval letter can have an expiration date, typically 30 to 60 days. Ask the lender for the exact date. If your search runs longer, the lender will usually need updated documents, and it may pull your credit again.
A preapproval also does not lock your interest rate. If rates rise before you lock, the amount you can borrow at the same payment may go down.
What can derail a preapproval?
A preapproval rests on assumptions. The CFPB suggests asking the lender what it assumed and whether anything could lead to a denial, a higher rate or higher costs later. Common pressure points line up with what the lender checked:
- Income changes: a job change, lost hours, or a shift from salary to commission.
- New debt: a car loan, new credit card balance or co-signed loan raises your monthly obligations.
- Asset changes: moving or spending down the money you planned to use for closing.
- Credit changes: late payments or new inquiries outside your shopping window.
- The property: an appraisal below the price, or a home that does not meet the loan program's rules.
- Rates and terms: a higher rate or different loan type than the letter assumed.
Tell your lender before you make a big financial change.
What should you ask a lender about its letter?
Since the terms vary, ask each lender to explain what its letter means:
- Did you check my credit, and was it a full credit report?
- Which documents did you verify: pay stubs, tax returns, bank statements?
- Has an underwriter reviewed my file, or only a loan officer?
- What loan type, rate and down payment did you assume?
- What price and monthly payment does the letter support, including taxes and insurance?
- When does the letter expire, and what do you need to renew it?
- What could cause a denial or a higher rate before closing?
Write down the answers so you can compare lenders on the same basis.
What happens if a lender won't issue a letter?
If a lender reviews your credit and declines to give you a letter, the CFPB says it must send you an adverse action notice. That notice explains the decision and can point you to what to fix. A housing counselor can also help you review your options.
Which one do you need?
A prequalification can help you set an early budget. When you are ready to make offers, many buyers get a preapproval, because it shows sellers that a lender has looked at your finances. The CFPB suggests asking a local real estate agent or housing counselor which kind of letter sellers in your area expect.
A letter is not the same as a Loan Estimate. A Loan Estimate is the official form that shows your rate and costs. You can get multiple preapprovals and Loan Estimates while you shop. Comparing Loan Estimates, not letters, is how you compare actual prices.
Example: timing your preapproval and rate shopping
The dates and terms below are hypothetical.
- You get preapproved on March 1. The letter expires in 60 days. March 1 + 30 days = March 31, and 30 more days = April 30.
- Your first mortgage credit check is March 1. Under the 45-day window the CFPB describes, other mortgage credit checks through March 1 + 45 days = April 15 count as one inquiry. Under the shortest 14-day window in the CFPB toolkit, the safe cutoff is March 1 + 14 days = March 15.
- You go under contract on April 20. Your letter is still valid, but you are outside both shopping windows. A new lender's credit check would be recorded as another inquiry. The CFPB says that is usually a small cost compared with the savings a better rate can bring.
Plan to request Loan Estimates from several lenders close together, ideally within the first 14 days after your first credit check.
Hypothetical example for illustration. The rates and prices are assumptions, not current pricing or an offer.
Questions people ask
Is a preapproval a guarantee that I will get the loan?
No. The CFPB says preapproval and prequalification letters are based on assumptions and are not guaranteed loan offers. Final approval comes after underwriting, an appraisal and verification of your information.
Can I get preapproved by more than one lender?
Yes. The CFPB says you can shop around and get multiple preapprovals and Loan Estimates. Mortgage credit checks within a 45-day window are recorded as a single inquiry.
Does a prequalification require a credit check?
It depends on the lender. Some prequalify you on self-reported information alone, and some check credit for either type of letter.
What if my preapproval letter expires?
Ask the lender to update it. You will usually need to provide current pay stubs and bank statements, and the lender may check your credit again.
Does a preapproval lock my interest rate?
No. A preapproval letter and a rate lock are separate. Ask the lender when and how you can lock a rate.
