How to Buy a Home With Bad Credit: A Realistic, Step-by-Step Guide
A less-than-perfect credit score doesn't automatically disqualify you from homeownership. Millions of Americans buy homes every year with credit scores in the 580–650 range. The key is knowing which loan programs are available at your score, what they cost, and how to navigate the process successfully. This guide gives you the full realistic picture — no false promises, no glossed-over costs.
Minimum Credit Scores by Loan Type
FHA Loans: The Primary Option for Lower Credit Scores
FHA loans are the most accessible mortgage for borrowers with credit scores in the 500–680 range. Key features:
- 580+ credit: 3.5% minimum down payment
- 500–579 credit: 10% minimum down payment
- More forgiving of credit history: Recent late payments, collections, and even bankruptcy (after 2 years) are more workable than with conventional loans
- Higher DTI allowed: FHA allows DTI up to 43–57% with compensating factors
The trade-off: FHA requires mortgage insurance premium (MIP) regardless of down payment, and with less than 10% down, it lasts the life of the loan. See our FHA vs Conventional guide and Mortgage Insurance guide for full cost analysis.
The Real Cost of a Lower Credit Score
Credit score dramatically affects both your mortgage rate and PMI cost on conventional loans:

Every 20-point credit score improvement typically saves 0.125–0.25% in mortgage rate. On a $300,000 loan over 30 years, going from 640 to 720 credit could save $50,000–$80,000 in total interest and PMI. Even 3–6 months of credit improvement before applying is worth significant money.
How to Improve Your Credit Score for a Mortgage
These strategies produce the fastest, most meaningful improvements for mortgage applicants:
1. Dispute Credit Report Errors (Fastest Impact: 30–60 Days)
Pull your free reports from all three bureaus at annualcreditreport.com. Up to 34% of reports contain errors according to Consumer Reports. Dispute any inaccurate information — wrong account information, fraudulent accounts, incorrect late payments, or payments marked late that were actually on time. Dispute with each bureau individually in writing; they have 30 days to investigate and respond.
2. Pay Down Credit Card Balances (Fast Impact: 30–60 Days)
Credit utilization — your balance as a percentage of each card's credit limit — is the second most important credit score factor. Lenders report balances monthly; once your lower balances are reported, your score improves. Target getting each card below 30% utilization, and ideally below 10% if possible.
3. Become an Authorized User on a Strong Account (30–60 Days)
If a family member with excellent credit adds you as an authorized user on a long-standing, low-balance account, the positive history of that account may appear on your credit report and boost your score. You don't need to use the card — just being listed as an authorized user can help.
4. Don't Close Old Accounts
Length of credit history accounts for 15% of your FICO score. Closing old accounts shortens your average account age and reduces available credit (raising utilization). Keep old accounts open, even if you don't use them.
5. Avoid New Credit Applications
Each hard inquiry from a new credit application reduces your score by a few points and stays on your report for 2 years. In the 6–12 months before applying for a mortgage, avoid applying for new credit cards, auto loans, or other credit products.
6. Build Positive Payment History (6–12 Months)
Payment history is the most important credit factor (35% of FICO). Set up automatic payments on every account to ensure nothing is missed. Even one missed payment can significantly damage your score. After 6–12 months of perfect payment history, your score will improve meaningfully.
Alternative Paths to Homeownership With Bad Credit
Rent-to-Own Agreements
Some sellers offer rent-to-own arrangements where a portion of rent is credited toward an eventual purchase. This can provide time to improve credit while effectively "saving" toward the down payment. These agreements require careful legal review — consult an attorney before signing.
Down Payment Assistance Programs
Many state and local housing agencies offer down payment assistance specifically designed for buyers with credit challenges. Some programs work with FHA loans and have no minimum credit score of their own. See our Down Payment guide for more on these programs.
Co-Borrower or Co-Signer
Adding a creditworthy co-borrower (who will also be on the title) or co-signer (who won't live in the home) can improve your approval odds and rate. However, the co-borrower/co-signer's credit, income, and debts all enter the picture, and they're equally responsible for the debt.
Should You Wait to Improve Credit or Buy Now?
This calculation is more complex than it appears. Consider:
- If home prices in your market are rising 5–8%/year, waiting 12 months to improve credit means the home costs $25,000–$40,000 more
- The interest savings from a 40-point credit improvement (over 30 years) might be less than the appreciation you missed
- Conversely, in flat or declining markets, waiting to improve credit clearly wins
