How Your Credit Score Impacts Buying a House: Minimum Scores, Loan Options & Ways to Improve Before You Buy

Excited to buy a home but nervous about your credit score? You’re not alone — and your credit is one of the biggest factors lenders look at when deciding whether to approve your mortgage and what terms you’ll get.

Whether you’ve been renting for years or living with family, the idea of finally owning your own place is both exciting and a little terrifying. Along with choosing neighborhoods, touring homes, and imagining paint colors, you also have to face the reality that buying a home is a major financial commitment — and lenders won’t just hand out hundreds of thousands of dollars without doing their homework.

One of the first things your lender will do when you apply for a mortgage is pull your credit report and credit scores. Those three-digit numbers tell banks and mortgage companies how risky (or safe) you’re likely to be as a borrower. Strong scores can mean easier approvals, lower interest rates, and better loan options. Weaker scores don’t necessarily shut the door, but they can make the process more challenging and expensive.

In this guide, I’ll break down how your credit score impacts buying a house, what’s considered “good enough,” what lenders are really looking at, and practical steps you can take to improve your scores before you start home shopping in the Greater Rochester NY area.

1. What Is a Credit Score?

A credit score is a three-digit number (typically ranging from about 300–850 in the U.S.) that summarizes how risky you are as a borrower based on your past and current financial behavior. Companies like Equifax, Experian, and TransUnion collect your data and score it using models such as FICO or VantageScore.

Your score is based on things like:

• Your history of on-time (or late) payments
• How much of your available credit you’re using
• How long you’ve been using credit
• The mix of accounts you have (credit cards, auto loans, student loans, etc.)
• Public records and negative items (collections, judgments, bankruptcies)
• Recent inquiries and new accounts

In simple terms, your credit score is your financial reputation on paper. The higher the number, the more comfortable lenders usually feel lending you money for major purchases like a home.

2. What’s Considered Good, Average, and Bad?

Different lenders and loan programs have slightly different cutoffs, but here’s a helpful way to think about credit scores in the context of buying a home:

Good Credit

A score in the mid-600s and up is generally considered “good” by many lenders. With scores in this range (and solid income, debt levels, and savings), you’re more likely to:

• Get approved more quickly and easily
• Qualify for better interest rates
• Pay lower fees and, in some cases, lower down payments

In other words, a strong credit profile doesn’t just help you get approved — it can save you tens of thousands of dollars over the life of your mortgage.

Average Credit

Scores in the low-to-mid 600s are often considered “average.” Many buyers fall in this category. You may still qualify for a mortgage, but:

• Your interest rate may be a bit higher
• You may have fewer loan program options
• You might face somewhat higher fees or mortgage insurance costs

It’s not a disaster — but you may want to work on your scores if you have time before you buy, especially in a competitive market.

Bad or Challenged Credit

Scores in the 300s–500s are generally considered “poor” or “challenged.” This doesn’t automatically mean you can’t buy a home, but it does mean:

• Fewer lenders and loan programs are available
• You may need a larger down payment or stronger compensating factors
• You’ll likely pay higher interest rates and fees

In some cases, you might be offered a “bad-credit mortgage” with stricter terms, but it’s often wiser to improve your credit first if you’re able. My guide on how to buy a house with a low credit score walks through your options in more detail.

3. How Lenders Use Your Credit Score When You Buy a House

When you apply for a mortgage, lenders are taking a calculated risk. They’re asking, “If we lend this person money for 15–30 years, how likely are we to be paid back on time, every month?”

Your credit score influences:

• Whether you’re approved at all for a given loan program
• Your interest rate (higher risk = higher rate)
• Required down payment and whether you qualify for low-down-payment options
• Mortgage insurance costs for conventional and FHA loans
• How underwriters view your file overall compared to other applicants

A higher score doesn’t guarantee approval — lenders also look at your income, employment, debts, and assets — but it does make your overall profile much stronger.

Understanding this is also why buyers should know why real estate agents ask for a pre-approval before touring homes — it strengthens your negotiating power and helps avoid surprises.

4. What Counts as “Good Enough” to Qualify for a Mortgage?

Every lender and loan program has its own guidelines, but as a general rule:

• Many conventional loans like to see scores in the 620+ range
• Some FHA loans can be available with scores starting around the 580s, sometimes lower with larger down payments
• VA loans (for eligible veterans and service members) can be flexible but still benefit from stronger credit

In very broad terms, if your score is in the mid-500s or higher, you may be able to qualify for certain traditional mortgage options — but your exact path forward will depend on your full financial picture and the lender you choose.

If you are a first-time buyer, it may also be worth exploring first-time home buyer programs, which can make qualifying easier even with moderate credit.

5. The 5 FICO Factors That Drive Your Score

Over 90% of top lenders use some version of the FICO score. It’s based on five main components:

• Payment history – 35%
• Credit usage (utilization) – 30%
• Age of credit accounts – 15%
• Credit mix – 10%
• New credit inquiries – 10%

The biggest pieces of the pie are your on-time payments and how much of your available credit you’re using. That’s good news — because those are also the areas where focused effort can make the biggest difference.

Next, let’s look at specific, practical ways to raise your credit score if it isn’t where it needs to be yet.

6. How to Raise Your Credit Score If It’s Too Low

If you’ve applied for a mortgage and been turned down — or you’re just proactive and want to strengthen your file — there are several steps you can take to improve your credit.

Step 1: Review Your Credit Reports

Start by finding out exactly where you stand. You can request a copy of your reports from each of the major credit bureaus — Experian, Equifax, and TransUnion — and you’re entitled to free reports periodically through the Annual Credit Report website.

Look for:

• Late or missed payments
• High balances on revolving credit (credit cards, lines of credit)
• Collections, judgments, or charge-offs
• Errors or accounts you don’t recognize

Disputing genuine errors and understanding exactly what’s hurting your score gives you a clearer roadmap for improvement.

Step 2: Prioritize On-Time Payments

Since payment history makes up 35% of your FICO score, nothing matters more than paying every bill on time, every month. To help with this:

• Set up automatic payments for at least the minimum amount due
• Use calendar reminders or budgeting apps to track due dates
• Contact creditors if you’re struggling; sometimes they’ll work with you

Even one 30-day late payment can do serious damage. The more consistent you are going forward, the more your score can recover over time.

Step 3: Keep Your Credit Utilization Around 30% or Less

Credit utilization is the portion of your available revolving credit that you’re actually using. It’s the second most important factor in FICO scoring.

As a rule of thumb, try to keep your balances under 30% of your total credit limits, and under 10% if possible. Ways to improve this:

• Pay down balances aggressively, starting with cards closest to their limits
• Make multiple payments throughout the month, not just one big payment
• Ask for a credit limit increase (and then don’t use the extra available credit)

Some people also direct-deposit their paycheck to quickly knock down card balances, then use the card responsibly for everyday spending — but this only works if you’re disciplined and avoid re-creating the debt.

Step 4: Limit New Credit Inquiries

Applying for new credit cards, auto loans, or personal loans causes “hard inquiries” on your reports, which can temporarily lower your scores. A few inquiries are normal; multiple applications in a short period can be a red flag.

If you’re working on your credit with the goal of buying a home, avoid unnecessary new credit applications until after you’ve closed on your house.

Step 5: Build Positive History Over Time

There’s no true “quick fix” for poor credit — but consistent, responsible behavior over time can absolutely turn things around. That means:

• Keeping older accounts open to build average account age
• Making on-time payments every month across all accounts
• Maintaining reasonable balances and avoiding maxed-out cards
• Using a small amount of credit regularly and paying it off

If your scores are lower now but you’re otherwise ready to buy a house, a history of responsible behavior over the next several months can make a big difference in how underwriters view your file.

7. Timeline: When to Start Fixing Your Credit Before Buying

Ideally, you’ll start looking at your credit 6–12 months before you’d like to buy a home. That gives you time to:

• Pull your reports and scores
• Dispute any errors or inaccuracies
• Pay down balances and lower utilization
• Build a track record of on-time payments

If you are early in the process, you may also find it helpful to review my guide to the top frequently asked questions from home buyers.

8. FAQs: Credit Scores & Buying a Home

Can I buy a house with bad credit?

In some cases, yes. Certain loan programs are more flexible, especially if you have strong income, a larger down payment, or other compensating factors. However, you’ll usually pay higher interest rates and fees, and your options will be more limited. Often, improving your scores first is the smarter long-term move.

How long does it take to improve a low credit score?

It depends on what’s hurting your credit. Paying down balances and reducing utilization can sometimes show results in a few statement cycles. Recovering from serious late payments, collections, or bankruptcies can take much longer. The key is to start now and be consistent.

Will checking my own credit score hurt it?

No. Checking your own credit reports and scores is considered a “soft inquiry” and does not hurt your credit. Only “hard inquiries” from new credit applications (like credit cards or auto loans) can temporarily lower your scores.

Should I close old credit cards before I apply for a mortgage?

Usually no. Closing older accounts can actually hurt your credit by reducing your total available credit and shortening your average account age. In many cases, it’s better to keep older accounts open and use them responsibly unless a lender or credit counselor specifically suggests otherwise.

9. Final Thoughts: Building Stronger Credit for Your Next Home

Your credit score is a big piece of the homebuying puzzle — but it’s not the only piece. Income, job stability, savings, debts, and the type of property you’re buying all come into play. The stronger your credit, the more options and negotiating power you’ll have when it’s time to choose a mortgage.

If you’re planning to buy a home in the Greater Rochester NY area, the smartest steps you can take now are to:

• Pull your credit reports and scores so you know where you stand
• Address late payments, high balances, and any errors on your reports
• Keep utilization low and avoid unnecessary new credit inquiries
• Talk with a trusted local lender and Realtor early in the process
