How to Improve Your Credit Before Buying a House in Texas

TL;DR: Improving your credit before buying a home in Texas means checking all three credit reports for errors, paying every bill on time, lowering credit card balances below 30% utilization, avoiding new credit applications, and waiting at least 6 months before applying for a mortgage. Most borrowers need a 620+ FICO score for conventional loans or 580+ for FHA.

Key Takeaways

• Payment history is 35% of your FICO score — one 30-day late payment can drop your score by 100+ points (myFICO, 2025)
• Credit utilization is 30% of your score — keep it under 30%, ideally under 10%
• Minimum credit scores range from 500 to 700 depending on loan type (FHA, conventional, VA, USDA, jumbo)
• The average purchase-loan borrower has a 737 FICO score (Optimal Blue / Bankrate, April 2025)
• 3–6 months of consistent good habits can meaningfully raise your score (Redfin, 2026)

Why Credit Matters When Buying in Texas

Your credit score is a three-digit number (300–850) that tells lenders how reliably you repay borrowed money. The higher your score, the more loan options you have and the lower your interest rate tends to be. Even a small difference in your mortgage rate can save — or cost — you thousands of dollars over the life of a loan. On a $350,000 loan (a typical amount in the Austin metro as of 2026), the difference between a 6.5% rate and a 7.0% rate is roughly $123 per month. Over 30 years, that adds up to more than $44,000 in additional interest.

According to Sully Ruiz, a licensed Texas REALTOR® (TREC #0742907) with Sully Realty Group who has helped 46+ families purchase homes in Central Texas, many buyers are surprised by how much even a 20-point score increase can improve their loan terms. Working with a knowledgeable lender early in the process helps you understand exactly what score you need for the program that fits your situation.

Minimum Credit Scores by Loan Type

Different mortgage programs have different minimum credit score requirements. Here is a breakdown based on 2026 lender guidelines:

Loan Type	Minimum Credit Score	Notes
Conventional	620 (some lenders 660+)	Fannie Mae / Freddie Mac backed
FHA	580 (or 500 with 10% down)	Government-insured
VA	No official min. (lenders want 620)	Veterans & active military
USDA	640	Rural & suburban eligible areas
Jumbo	680–700	Non-conforming loan limits

Sources: Bankrate, Redfin, myFICO — 2025–2026

Meeting the minimum does not mean you will get the best rate. According to mortgage technology provider Optimal Blue, the average credit score for borrowers getting a purchase loan was 737 as of April 2025 data cited by Bankrate. The national average FICO score was 715 in 2024, according to Experian.

If your score is below these benchmarks, do not panic. There is time to improve it.

What Makes Up Your FICO Score

Before you can improve your credit, you need to understand what factors influence it. Your FICO score — the scoring model used by most mortgage lenders — is calculated using five categories, according to myFICO:

Factor	Weight	What It Measures
Payment History	35%	On-time payments, late payments, collections
Amounts Owed (Utilization)	30%	Balances vs. total available credit
Length of Credit History	15%	Age of oldest and average accounts
New Credit	10%	Recent applications and hard inquiries
Credit Mix	10%	Variety of installment and revolving accounts

Source: myFICO, 2025

Payment history is the single largest factor. One 30-day late payment can drop a high score by 100 points or more, according to myFICO. Credit utilization — the ratio of your balances to your credit limits — is the second most impactful factor. If you have $10,000 in available credit and carry $3,500 in balances, your utilization is 35%, which is above the recommended 30% threshold.

7 Steps to Improve Your Credit

Step 1: Check Your Credit Reports From All Three Bureaus

Get free copies of your credit reports from Equifax, Experian, and TransUnion at AnnualCreditReport.com. You are entitled to one free report from each bureau per year.

Review every report carefully for:

• Late payments that you believe were made on time
• Accounts that do not belong to you
• Incorrect balances or credit limits
• Outdated negative items that should have fallen off (most negatives stay for seven years)

If you find errors, dispute them directly with the credit bureau. Correcting a single error can sometimes raise your score by dozens of points.

Step 2: Pay Every Bill on Time — No Exceptions

Since payment history is 35% of your FICO score, this is where the biggest gains come from. Late payments can stay on your credit report for up to seven years, according to Equifax.

Set up automatic payments or calendar reminders for every account. If you have past-due accounts, get current as quickly as possible. Even if you can only make the minimum payment, paying on time is far better than paying late.

Step 3: Reduce Your Credit Card Balances

Your credit utilization ratio is the second most important factor (30%). The lower your utilization, the better.

• Aim for under 30% utilization on each card and across all cards combined.
• Under 10% is ideal for maximizing your score before a mortgage application.
• Pay balances before the statement closing date, not just the due date. Credit card companies report your balance to the bureaus when your statement closes, so paying early ensures the low balance is what gets reported.

For example, if you have a card with a $5,000 limit and your statement typically shows a $2,500 balance, your utilization is 50%. If you pay $1,500 before the statement closes, the reported balance drops to $1,000 — bringing your utilization to 20%.

Step 4: Ask for a Credit Limit Increase

If you have a history of on-time payments with your credit card issuers, call and request a credit limit increase. This does not mean you should spend more — it simply increases your total available credit, which lowers your utilization ratio.

For example, if you currently have $8,000 in total credit limits and carry $2,400 in balances (30% utilization), getting a limit increase to $12,000 drops your utilization to 20% without paying down a single dollar.

Ask if the lender can do a "soft pull" rather than a hard inquiry, since hard inquiries temporarily lower your score.

Step 5: Do Not Open New Credit Accounts

In the six to twelve months before applying for a mortgage, avoid opening new credit cards, taking out auto loans, or applying for store credit. Each new application triggers a hard inquiry that can lower your score by a few points. New accounts also reduce the average age of your credit history.

If you absolutely must apply for credit during this period, be prepared to explain the inquiry to your mortgage lender. And never open new accounts during the underwriting process — this can derail a loan already in progress.

Step 6: Do Not Close Old Accounts Either

It might seem logical to close credit cards you no longer use, but doing so can actually hurt your score. Closing an account reduces your total available credit (raising your utilization ratio) and shortens your average credit age.

If a card has an annual fee you no longer want to pay, ask the issuer about downgrading to a no-fee version instead of closing the account. This keeps the account open and preserves your credit history.

Step 7: Consider Becoming an Authorized User

If you have a thin credit file or a short credit history, ask a family member with a strong credit profile to add you as an authorized user on one of their credit cards. You do not need to use the card — simply being listed as an authorized user can import their positive payment history onto your credit report.

This strategy is especially helpful for immigrants and first-generation homebuyers who may not have established credit histories in the United States. According to Experian, authorized user accounts can have a meaningful impact on credit scores, particularly for those with limited credit history.

Special Considerations for Texas Homebuyers

Texas-Specific Loan Programs

Texas offers several programs that may have more flexible credit requirements than conventional loans:

• Texas Department of Housing and Community Affairs (TDHCA) — Offers first-time homebuyer programs with down payment assistance. Some programs accept credit scores as low as 620.
• My First Texas Home — A statewide program combining 30-year fixed-rate mortgages with down payment assistance grants. Credit requirements vary by lender but generally start at 620.
• ITIN Loans — For buyers without a Social Security Number, some Texas lenders offer ITIN mortgage programs. These typically require alternative credit histories (utility bills, rent payments) rather than traditional FICO scores.

If you are exploring ITIN loan options, book a free screening with Sully Ruiz to understand which programs you may qualify for.

Property Tax Considerations

Texas has no state income tax, but property taxes are among the highest in the nation. While property taxes do not directly affect your credit score, they factor into your overall debt-to-income (DTI) ratio. Make sure you account for property tax escrow when calculating how much home you can afford — lenders certainly will.

How Long Does It Take to Improve Your Credit?

According to Redfin, the average credit repair timeline is 3 to 6 months, though this depends on your starting point and what needs fixing.

Action	Timeline
Disputing report errors	30–60 days for bureau investigation
Paying down balances	Immediate impact once lower balance is reported
Authorized user boost	1–2 billing cycles
Building payment history	Gradual, month-over-month improvement

If you have major negative items (bankruptcies, foreclosures, collections), the timeline extends significantly. Chapter 13 bankruptcies stay on your report for seven years; Chapter 7 for ten years. But even with past negatives, consistent positive activity can raise your score meaningfully within a year.

What Score Should You Target?

Rather than just aiming for the minimum, set a target that gives you real options:

Target Score	What It Unlocks
620+	Conventional and FHA loan eligibility (rates may be higher)
680+	Better rates, more lender options, lower PMI costs
740+	Best available interest rates across all loan types

If your current score is in the 500s or low 600s, targeting 680 is a realistic and impactful goal. The difference between a 580 score and a 680 score could mean qualifying for a conventional loan instead of an FHA loan — potentially saving you from paying mortgage insurance for the life of the loan.

Beyond Credit: Other Factors Lenders Consider

While credit score is critical, mortgage lenders also evaluate:

• Debt-to-Income (DTI) Ratio — Most lenders want your DTI below 43%, though some programs allow higher. Calculate this by dividing total monthly debt payments by gross monthly income.
• Employment History — Lenders typically want two years of consistent employment. If you recently changed jobs, be prepared to explain.
• Down Payment — Some programs allow zero down (VA, USDA) or 3.5% down (FHA). A larger down payment can improve your loan terms.
• Savings and Reserves — Lenders want to see 2–6 months of mortgage payments in reserve after closing.

FAQ

Can I buy a house with a 580 credit score in Texas?

Yes, you may qualify for an FHA loan with a 580 credit score and a 3.5% down payment. However, some lenders require 640+ even for FHA. Conventional loans require a minimum of 620.

How fast can I raise my credit score?

Paying down credit card balances can produce results within one billing cycle (30 days). Disputing errors takes 30–60 days. Building consistent payment history improves your score gradually over 3–6 months or more.

Does checking my own credit hurt my score?

No. Checking your own credit report is a "soft inquiry" and does not affect your score. Only "hard inquiries" from lender applications temporarily lower your score.

Should I pay off all my debt before applying for a mortgage?

Not necessarily. Having some active credit accounts demonstrates responsible credit use. Focus on lowering credit card balances (utilization) and keeping accounts in good standing rather than zeroing everything out.

Can I get a mortgage with no credit history in Texas?

Yes. Some lenders offer ITIN loans and alternative-credit programs that use rent payments, utility bills, and other history instead of traditional FICO scores. Contact Sully Ruiz to explore your options.
