How to Improve Your Credit Score Before Buying a Home

7 min read Updated 2026-02-06

Your credit score is one of the most powerful factors in determining how much home you can afford. A 100-point difference can mean 0.5-1% in mortgage rate difference. On a $300,000 loan, that's over $60,000 in additional interest. Here's the truth: you can meaningfully improve your credit score in 3-6 months with the right strategy.

Credit Score Requirements by Loan Type

VANo official minimum620+ recommended

What Makes Up Your Credit Score

  • Payment History (35%) - Most important. One late payment can drop your score 50-100 points
  • Credit Utilization (30%) - Keep below 30%, ideally under 10%
  • Length of Credit History (15%) - Average age of accounts matters
  • Credit Mix (10%) - Different types of credit help
  • New Credit (10%) - Recent inquiries and new accounts

Quick Wins (30-60 Days)

Pay down credit card balances - this is the fastest way to improve your score. Dispute errors on your credit report (20% contain mistakes). Become an authorized user on a family member's old, low-utilization card. Request credit limit increases (soft inquiry only).

Medium-Term Strategies (3-6 Months)

Set up autopay for at least minimum payments on every account. Keep old accounts open even if unused. Avoid opening new credit accounts 6 months before mortgage application. Consider a secured credit card if rebuilding from scratch.

Credit Myths Debunked

  • Checking your own credit does NOT hurt your score (it's a soft inquiry)
  • You do NOT need to carry a balance to build credit
  • Closing old cards HURTS your score, not helps it
  • Income is NOT part of your credit score
