How to Improve Your Credit Score to Buy a House
A higher credit score means a lower rate. Here's how to move the needle fast before you apply for a mortgage.
A higher credit score means a lower rate. On a $400,000 loan, the difference between a 640 and a 740 can be $200–$300 a month. Over 30 years, that's real money.
Here's how to move the needle — fast.
First: know where you stand
Pull your credit before you do anything else. Go to annualcreditreport.com — it's free and it's the official site. You'll see your report from all three bureaus: Experian, TransUnion, and Equifax.
Mortgage lenders use all three and take the middle score. So if your scores are 680, 710, and 720 — your qualifying score is 710.
The fastest levers
1. Pay down credit card balances
This is the single fastest way to raise your score. Credit utilization — how much of your available credit you're using — makes up 30% of your score.
Get every card below 30% of its limit. Below 10% is even better.
Example: You have a card with a $10,000 limit and a $6,000 balance. That's 60% utilization — hurting your score. Pay it to $1,000 and watch your score jump. This can happen within one billing cycle.
2. Don't close old accounts
Length of credit history matters. Closing an old card shortens your average account age and reduces your available credit — both hurt your score. Keep old cards open even if you don't use them.
3. Don't open new accounts
Every new application triggers a hard inquiry. Hard inquiries drop your score by a few points each and stay on your report for two years. In the months before buying a house, don't apply for anything new — no new cards, no car loans, nothing.
4. Dispute errors
Errors on credit reports are more common than people think — wrong balances, accounts that aren't yours, late payments that were actually on time. Dispute them directly with each bureau. Fixing an error can jump your score significantly.
Go to equifax.com, experian.com, and transunion.com to file disputes directly.
5. Become an authorized user
If a family member has a credit card with a long history and low utilization, ask them to add you as an authorized user. Their account history shows up on your report. You don't even need to use the card.
What doesn't work
Credit repair companies that charge upfront fees — most do nothing you can't do yourself. 'Pay for delete' letters — sometimes work, often don't, and can backfire. Closing cards to 'simplify' your credit — this hurts, not helps.
How long does it take?
Paying down balances: score moves within 1–2 billing cycles (30–60 days). Disputing errors: 30–45 days for bureaus to respond. Building new history: 6–12 months.
If you're 60–90 days from buying, focus on utilization and errors. That's where the fastest gains are.
