A low credit score does not automatically close the door on buying a house. Here are the loan options that actually work with bad credit, a path called manual underwriting that most buyers have never heard of, and exactly what a low score costs you if you don't fix what you can first.

Buying a house with bad credit is genuinely harder, but it is not the closed door most people assume. FHA loans accept scores as low as 500, VA loans have no official minimum from the VA itself, and a process called manual underwriting exists specifically for borrowers whose full financial picture is stronger than their credit score alone suggests.
This guide covers the real loan options at different credit levels, how manual underwriting actually works, and the specific factors that can offset a low score in a lender's eyes.
Quick honesty note
This is education, not financial advice. Credit score requirements, DTI limits, and lender overlays vary and change over time.
Every lender sets its own additional requirements on top of program minimums, so shopping multiple lenders matters more with bad credit than with good credit.
The Short Answer
In short: You can buy a house with a credit score as low as 500 through an FHA loan (with 10% down), or 580 with just 3.5% down.
Scores below 620 trigger mandatory manual underwriting, where a human reviews your full financial picture rather than an algorithm making an instant decision, and strong compensating factors like cash reserves or a clean rental payment history can offset the lower score.
What Counts as Bad Credit

| FICO range | Category |
|---|---|
| 740+ | Excellent, best rates |
| 670-739 | Good |
| 580-669 | Fair, often called "bad credit" in mortgage terms |
| 500-579 | Poor, limited but real options remain |
There is no single mortgage-industry definition of "bad credit." A score that one lender rejects, another may approve, since individual lenders set their own overlays on top of a loan program's official minimum.
This is exactly why shopping multiple lenders matters more with a lower score, not less.
Your Loan Options With Bad Credit
- FHA loans. Accept scores as low as 580 with 3.5% down, or 500 with 10% down. The most accessible mainstream option for lower scores.
- VA loans. No official minimum score set by the VA itself for eligible veterans and service members, though individual lenders commonly apply their own minimum, often in the 580-620 range.
- USDA loans. Generally want a score around 640 for automated approval, though manual underwriting paths exist for eligible rural-area buyers below that.
- Non-QM or portfolio loans. Held by lenders directly rather than sold to Fannie Mae or Freddie Mac, offering more flexibility for unusual credit situations, typically at a higher rate.

Manual Underwriting, the Path Most People Don't Know About
As of current HUD guidance, any FHA loan with a credit score below 620 must go through manual underwriting, meaning a real underwriter reviews your complete file rather than an automated system rendering an instant decision.
This is not a consolation prize, it is a genuine, common approval path.
A "refer" is not a denial
When Fannie Mae's Desktop Underwriter or FHA's TOTAL Mortgage Scorecard returns a "refer" instead of an outright "approve," many borrowers assume they have been rejected. They have not.
A refer simply routes the file to a human underwriter, who reviews your full picture against documented compensating factors that automated systems tend to underweight.
Per HUD's underwriting guidance, compensating factors a manual underwriter can credit include:
- Verified rental payment history. 12 to 24 months of on-time rent, confirmed by canceled checks or a professional property manager's verification.
- Cash reserves. Commonly 3 or more months of PITI held in reserve after closing.
- Low DTI relative to the program ceiling. For example, a 40% DTI when the program technically allows up to 50%.
- Stable, multi-year employment with the same employer.
Manually underwritten FHA loans can also approve debt-to-income ratios up to roughly 40% front-end and 50% back-end with strong compensating factors, well above the standard 31%/43% caps.
Non-traditional credit, documented rent, utility, and insurance payments, can also support an application for borrowers with limited traditional credit history.
Medical collections are generally excluded from the DTI calculation entirely, and non-medical collections over $2,000 may require only a calculated payment rather than being paid off.
Compensating Factors That Offset Bad Credit
Beyond the specific FHA list above, lenders broadly weigh a larger down payment, a longer job history, minimal increase from your current housing payment, and any documented additional income not otherwise used to qualify.
Stacking two or three of these meaningfully improves your odds versus relying on any single factor alone.
Quick Ways to Improve Your Score Before Applying
- Pay revolving balances below 30% utilization. This alone can improve a score by roughly 20 to 50 points within a single billing cycle.
- Dispute reporting errors. Pull all three credit reports and challenge anything inaccurate.
- Avoid new credit applications in the months before applying for a mortgage.
- Keep older accounts open. Length of credit history is a real factor in your score.
FICO weighs payment history most heavily at 35%, followed by amounts owed at 30%, length of history at 15%, credit mix at 10%, and new credit inquiries at 10%, which is why paying down balances and avoiding new accounts move the needle faster than almost anything else.
What a Low Score Actually Costs You
The difference between a 580 and a 740 credit score can mean roughly $200 to $300 more per month on a $300,000 loan, purely from the rate difference.
That gap is exactly why even a modest, achievable credit improvement before applying can be worth delaying your purchase by a few months.
Bankruptcy and Foreclosure Waiting Periods
FHA loans generally require a waiting period after a bankruptcy discharge or foreclosure, commonly around three years from a foreclosure's completion.
An exception can apply, sometimes reducing the wait to two years, if the event resulted from a single documented extenuating circumstance, such as a major medical emergency or the death of a wage earner, combined with strong compensating factors and manual underwriting approval.
Common Mistakes (and How to Dodge Them)
- Assuming a "refer" means denied. It means manual underwriting, a real and common approval path, not a rejection.
- Only checking one lender. Overlays vary significantly; a rejection at one lender does not mean rejection everywhere.
- Opening new credit or financing a purchase before closing. This can change your DTI enough to jeopardize an already-approved loan.
- Ignoring documentable rental history. Twelve to twenty-four months of on-time rent, properly verified, is a real compensating factor most renters do not think to document in advance.
- Paying for credit repair services for things you can do yourself. Disputing errors and paying down utilization cost nothing and often move your score faster than a paid service.
Frequently Asked Questions
What credit score do I need to buy a house?
FHA loans accept scores as low as 580 with 3.5% down, or 500 with 10% down. VA loans have no official minimum set by the VA itself, though lenders typically apply their own overlay, often 580 to 620. Conventional loans usually want at least 620.
Individual lenders can set stricter requirements on top of these program minimums.
What is manual underwriting for a mortgage?
Manual underwriting is when a human underwriter reviews a loan file directly, rather than an automated system rendering an instant decision.
It is required for FHA loans with credit scores below 620, and also happens when an automated system returns a "refer" rather than an "approve," which is not a denial but a routing to human review of your full financial picture.
Can I get approved for a mortgage if an automated system says "refer" instead of "approve"?
Yes, often. A "refer" result means a human underwriter will review your complete file against documented compensating factors, such as cash reserves, verified rental payment history, or stable long-term employment, that automated systems tend to underweight. Many borrowers who receive a refer are ultimately approved.
What are compensating factors in mortgage underwriting?
Compensating factors are strengths in your financial profile that can offset a weaker credit score, including verified on-time rental payment history, cash reserves of three or more months of housing payments, a debt-to-income ratio well below the program's maximum, and stable multi-year employment with the same employer.
Manual underwriters weigh these when a score alone would not clear automated approval.
How much more does a mortgage cost with bad credit?
The rate difference between a low score, around 580, and a strong score, around 740, can add roughly $200 to $300 to a monthly payment on a $300,000 loan.
This gap is a major reason it is often worth spending a few months improving your score before applying, since even a modest improvement can meaningfully lower your long-term cost.
How long do I have to wait to buy a house after bankruptcy or foreclosure?
FHA loans commonly require around a three-year wait after a foreclosure's completion, though this can sometimes be reduced to two years if the event resulted from a single documented extenuating circumstance, combined with strong compensating factors and manual underwriting approval.
Waiting periods and exceptions are set by HUD and can change, so confirm current requirements with a lender.
A Low Score Is a Setback, Not a Wall
Buying a house with bad credit takes more documentation, more patience, and often a manually underwritten loan, but it is genuinely achievable through FHA, VA, and non-QM options.
Fix what you can quickly, like credit utilization, document what compensates for the rest, like rental history and reserves, and shop multiple lenders since overlays vary more than most buyers expect.
