A pre-approval letter tells a seller that a lender has already looked at your finances, so your offer reads as one that can close. It isn’t a promise to lend, but it’s the closest thing to one before you’ve
Pre-approval vs. pre-qualification: what’s the difference?
Lenders use the two words differently, and the Consumer Financial Protection Bureau says not to worry much about the label. The useful difference is evidence. A pre-qualification is often based on what you tell the lender. A pre-approval is based on documents the
So judge a letter by what stands behind it. Ask the lender what they verified. A letter backed by pay stubs, tax returns, bank statements and a credit report carries more weight with a seller than one built on
What does a lender check?
Expect a credit check and requests for proof of income, such as recent pay stubs, W-2s or tax returns, plus bank statements showing the money for your down payment and closing costs. If a relative is giving you part of that money, the lender will usually want a gift letter.
From those documents the lender works out your debt-to-income ratio and checks your credit score against the loan programs you might use. The result is a maximum loan amount, usually tied to an assumed price, down payment
Does getting pre-approved hurt your credit?
A little. A pre-approval usually involves a credit check, and inquiries can lower a score slightly. Shopping around costs less than people fear: the CFPB notes that multiple mortgage credit checks within a 45-day window are recorded as

Is the pre-approved amount your budget?
Not necessarily. The number on the letter is the most a lender will lend, not what you’ll be comfortable paying. Your monthly payment also includes property taxes, homeowners insurance, any HOA dues and, with less than 20% down on a conventional

Common mistakes
- Treating the pre-approved amount as a budget instead

furniture before closing. - Assuming a pre-qualification carries the same weight with a seller
as a pre-approval. - Letting the letter expire mid-search without sending the
lender updated documents.
Questions
How long does a pre-approval last?
Until the date on the letter, which each lender sets. If it expires, the lender will usually ask for updated pay stubs and bank statements and may check
Can you be denied after pre-approval?
Yes. Final approval depends on underwriting, the appraisal and your finances staying the same through closing, so a change in income, debt or credit can still
Do you need a pre-approval to make an offer?
Usually it isn’t required, but many sellers expect one and some won’t consider an offer without it. Ask your agent what sellers in your market
