When you're preparing to buy a home, your credit score plays a starring role in the process. Not only does it determine your eligibility for various loan programs, but it directly impacts the interest rate you qualify for—potentially saving or costing you thousands of dollars over the life of your mortgage.
Whether you’re planning to buy in six months or a year, here are essential tips to build, protect, and optimize your credit score for pre-approval success.
Your credit utilization ratio—how much of your available revolving credit you are currently using—account for roughly 30% of your credit score. Lenders prefer to see utilization below 30% on each card (and ideally under 10% for the highest credit tier).
Pro Tip: Paying down high-balance credit cards is often the fastest way to see an immediate boost in your score before starting your loan application.
When you’re gearing up to buy a house, aim to keep your credit profile as stable as possible:
Payment history accounts for a massive 35% of your total credit score. Even a single late payment (30+ days past due) can cause a score to drop significantly. Setting up automatic minimum payments on all revolving accounts ensures you never miss a deadline during your home-buying journey.
The Golden Rule Before Closing:
Once you are under contract or pre-approved, do not make major purchases on credit (like buying furniture, appliances, or a new vehicle) until after your loan has formally closed and funded.
Inaccurate accounts, incorrect collection status, or outdated personal details can drag down your score without your knowledge. Pulling your official reports early gives you time to dispute errors with credit bureaus before you apply for a mortgage.
