A pre-approval letter is a lender's statement that they are tentatively willing to lend you money, up to a certain loan amount. The Consumer Financial Protection Bureau is clear about two things: the letter is not a guaranteed loan offer, and sellers frequently require it before accepting an offer. To issue one, a lender reviews your financial picture, usually by verifying your income, assets, and debts and pulling your credit. The words pre-qualification and pre-approval get used differently by different lenders, so ask each lender exactly what their letter is based on. For Fairfax buyers touring homes this weekend, that letter is the financial proof behind everything else you do.
Here's where the letter earns its keep. When you write an offer, your agent attaches the pre-approval letter, and the listing agent uses it to judge whether your offer can actually close. In competitive Northern Virginia markets, an offer without one reads as unserious: the seller has no evidence a lender has looked at your finances. A strong letter can even beat a slightly higher offer from a buyer who skipped that step. Around Reston, where well-priced homes draw multiple offers, agents on both sides treat the letter as table stakes.
Timing matters because the letter has a shelf life. Lenders typically check your credit before issuing a pre-approval, and the letter usually carries an expiration date, commonly 30 to 60 days, according to the CFPB. That doesn't mean you should browse homes in Woodbridge for months without one, then scramble when you find the one. A good rhythm: get pre-approved when you're ready to tour seriously, renew it if your search runs long, and protect the file while you search. Don't open new credit cards, finance a car, or change jobs mid-search without telling your lender first.
Getting the letter is straightforward. Give a lender your income, assets, and debts, answer their questions, and let them verify. Ask what assumptions the letter is based on, and what could change the outcome before closing. You're not locked to that lender: getting pre-approved with one bank doesn't stop you from shopping rates with another, and the CFPB encourages rate-shopping. If you're using a Virginia Housing program, you'll apply through one of their participating lenders, and the pre-approval is part of that same process.
FAQ
Is a pre-approval letter the same as a pre-qualification letter?
Not necessarily. Lenders use the terms differently. Generally, a pre-qualification is an estimate based on financial information you report yourself, while a pre-approval is based on documented, verified information and usually a credit check. The CFPB's advice: don't fixate on the label. Ask the lender what their letter is based on, and ask your agent which version carries more weight with local sellers.
How long does a pre-approval letter last?
Most carry an expiration date, commonly 30 to 60 days. If your search runs longer, your lender can usually renew or update the letter with fresh documentation. Let your agent know the expiration date so neither of you gets surprised mid-negotiation.
Will getting pre-approved hurt my credit score?
The lender typically runs a hard credit inquiry for a pre-approval, which can move your score slightly. That's normal and expected in the mortgage process. What's worth avoiding is new credit activity afterward: opening cards or financing purchases before closing can change the numbers your pre-approval was based on.
Do I have to use the same lender who pre-approved me?
No. The pre-approval letter is not a commitment to borrow from that lender. You can keep shopping for better rates and terms, and many buyers do. Just make sure whichever lender you choose can hit your closing timeline.
