Prequalification is a quick, mostly self-reported estimate of what you might borrow, based on numbers you provide without verification. Preapproval is a real application, a credit pull, submitted pay stubs, tax returns, and bank statements, reviewed by an underwriter, that results in a conditional commitment letter. The difference matters the moment you make an offer, because sellers and their agents can usually tell the two apart, and in a competitive market a prequalification letter carries far less weight than a preapproval.
The core idea
Both terms describe an early step in the mortgage process, but they differ in how much verification actually happened behind the estimate.

A prequalification is useful for a rough sense of your budget early on. A preapproval is what you actually want in hand before you start touring homes seriously or writing offers.
How to move from one to the other
- Start with prequalification if you are just exploring. It costs nothing and gives you a ballpark range without a hard credit inquiry.
- Gather your documents before applying for preapproval, recent pay stubs, W-2s or tax returns, bank statements, and any documentation for additional income.
- Apply with a lender for preapproval once you are seriously house hunting. Expect a hard credit pull and a request for the documents above.
- Get the conditional commitment letter in writing, including the loan amount, rate assumptions, and any conditions that still need to be met.
- Refresh it if your search runs long. Most preapproval letters are valid for a limited window, often somewhere around 60 to 90 days, and need updated documents if that window passes.
Common mistakes
- Shopping for homes with only a prequalification letter. In a competitive market, sellers often favor offers backed by real preapproval, since it reflects actual underwriting review.
- Assuming preapproval guarantees final approval. Your loan is still subject to appraisal, title review, and any conditions the underwriter listed, it is a strong signal, not a guarantee.
- Letting a preapproval expire mid-search. An expired letter needs refreshed documents and a new credit pull before it is valid again.
- Applying for new credit after preapproval. A new auto loan or credit card between preapproval and closing can change your debt-to-income ratio enough to affect final approval.
FAQ
Does getting prequalified hurt my credit score?
Usually not, since many prequalifications rely on self-reported information or a soft credit check that does not affect your score. Preapproval typically involves a hard inquiry, which can cause a small, temporary dip.
How long does a mortgage preapproval last?
Commonly somewhere around 60 to 90 days, though it varies by lender. Confirm the specific expiration on your letter.
Can I get preapproved by more than one lender?
Yes, and comparing preapproval terms from a few lenders is a reasonable way to shop, since multiple mortgage inquiries within a short window are typically treated as a single inquiry for credit scoring purposes.
Does a preapproval letter guarantee my loan will close?
No. It is a conditional commitment based on the information reviewed so far, appraisal results, title issues, or changes in your financial picture before closing can still affect the outcome.
Where to go next
Once you have a preapproval in hand, the next steps move quickly. See how rate locks work, check down payment assistance programs if you need help with your down payment, and review what PMI costs if you are financing with less than 20 percent down.
