The short answer is… your credit score will likely dip a little when you buy a home, and it'll typically recover within about a year, often faster if you keep doing the boring, responsible things you were already doing to qualify for the mortgage in the first place. Here's what's actually happening, and what it means if you're buying in Alameda right now.
What Actually Moves the Number
Three things happen at once when you get a mortgage, and each one nudges your score:
- A hard inquiry hits your report every time a lender pulls your credit. Most scoring models are built to recognize you’re rate-shopping, not opening five separate loans, inquiries within the same short window (typically two to six weeks, depending on the model) get bundled and treated as one pull. So getting quotes from three lenders shouldn’t cost you three inquiries’ worth of points.
- A brand-new account lowers the average age of your credit file. A 15-year-old mortgage helps your score; a brand-new one is, for a little while, an unknown.
- Your utilization shifts. Most people’s mortgage balance dwarfs the rest of their debt, which changes the math your score is doing, even though a mortgage is installment debt and gets weighed differently than a credit card balance.
None of this is a red flag. It’s just the mechanics.
How Long it Takes
LendingTree tracked more than 6,000 homebuyers across the 50 largest U.S. metros and found scores dropped an average of about 20 points after closing, bottomed out around five and a half months later, and were back to their pre-loan level roughly a year after that, about 339 days start to finish. Sacramento buyers had it easiest in the entire study, with the smallest average drop of any metro at 13.5 points. If you’re buying with a strong file already, most people in this study started around 736, a temporary dip isn’t going to touch your ability to refinance, get a HELOC for that kitchen project, or qualify for anything else down the line.
What Bay Area Buyers Need to Know
Between Pre-approval and Closing, Do Not:
- Open any new credit – cards, auto loans, “no interest for 12 months” furniture financing, all of it
- Close old accounts, even ones you don’t use (it shortens your history and can raise utilization elsewhere)
- Make large, unexplained deposits or move money between accounts without a paper trail
- Change jobs or pay structure if you can help it
- Co-sign for anyone else’s loan
After You Close:
- Keep paying everything on time. Payment history is the single biggest factor in your score, and a mortgage paid on time every month is one of the best long-term things you can do for your credit
- Don’t panic if your score dips a bit in month two or three; that’s the study above playing out exactly as expected
- Give it time. The recovery is boring and automatic if you don’t introduce new variables

Frequently Asked Questions
Will checking my own credit score hurt it before I buy?
No. Checking your own score is a soft pull and doesn't affect your credit at all. It's only when a lender pulls your file to actually underwrite a loan that it counts as a hard inquiry.
How many points does my score usually drop?
On average, about 20 points nationally, though it varies by metro and by how strong your file was going in. If you're already sitting in the high 700s, the dip is proportionally smaller.
Can I get quotes from more than one lender without tanking my score?
Yes, as long as you do it in a short window. Scoring models are built to recognize rate-shopping and bundle those inquiries together, it's spreading your lender search out over months, not comparing three quotes in two weeks, that costs you.
Should I pay off other debt before buying, or wait?
Talk to your lender before moving money around. Paying down a card can help your utilization, but a large, unexplained account change right before closing can also slow down underwriting. Timing matters more than the payoff itself.
How soon after closing can I open a new credit card or finance furn
iture.
Give it a few months. Your file is most sensitive to new accounts right around closing, when your lender may still be doing final checks. Once you've made a couple of mortgage payments, a new account is a much smaller deal.
