How to Buy a House With Bad Credit

By Aaron Eller, Founder — Cash Offer Man | St. Louis, Missouri

May 9, 2026

Bad credit does not permanently disqualify you from homeownership. That is the headline, and it is worth stating clearly before anything else, because the belief that a damaged credit score means renting forever is both common and wrong. Millions of Americans with credit histories that include late payments, collections, bankruptcies, and foreclosures have become homeowners — including in the St. Louis market, where I have personally watched buyers with sub-600 scores navigate FHA financing and close on their first home.

But — and this is an equally important truth — buying a home with genuinely bad credit requires either accepting significant costs and constraints that do not apply to borrowers with strong scores, or doing the work to fix the credit before purchasing. Which path is right depends on your specific situation, your timeline, and your financial discipline.

I am Aaron Eller, founder of Cash Offer Man, a local home buying company in St. Louis. I work with buyers and sellers across every credit profile in this market. I have seen bad credit delay purchases, increase costs, and in some cases derail transactions entirely. I have also seen people do the work — methodically, over 12 to 24 months — and transform a 540 credit score into a 680 that qualifies for competitive FHA rates. This article gives you the honest, data-driven picture of every dimension of this topic.

What Is Considered Bad Credit for a Home Purchase?

Before strategies, the definitions. “Bad credit” means different things depending on who is evaluating it and for what purpose.

The Credit Score Ranges You Need to Know

FICO scores — the scoring model used by approximately 90% of U.S. lenders — range from 300 to 850. The mortgage industry uses the following informal classifications:

For mortgage purposes, “bad credit” begins at approximately 620 — the threshold below which conventional loan access becomes very limited. Below 580, even FHA financing becomes restricted. Below 500, there is no standard mortgage program that will lend to you regardless of other factors.

The Three-Score System and Why It Matters

Mortgage lenders pull credit reports from all three major bureaus — Equifax, Experian, and TransUnion — and use the middle score of the three for underwriting purposes. This is important because your scores from the three bureaus often differ by 10 to 40 points, and the lender is using neither the best nor the worst.

If your Equifax score is 605, your Experian is 588, and your TransUnion is 621, the lender is using 605 — your middle score. Understanding this before you apply prevents the surprise of being told your “credit score” is different from what you saw on Credit Karma.

How to Fix Your Credit Before Buying: Tools, Techniques, and Timelines

If your score is below 620 and you have the time to work on it, credit repair is almost always the right path before purchasing. The mathematical reality is straightforward: every 20-point improvement in credit score translates to meaningfully lower mortgage rates and insurance costs that persist for the entire life of the loan.

Step 1: Pull Your Credit Reports and Find Every Error

Under the Fair Credit Reporting Act (FCRA), you are entitled to one free credit report per year from each bureau at AnnualCreditReport.com — the official, federally mandated site. Do not pay for reports or use third-party sites that charge fees for what the law requires to be free.

Pull all three reports simultaneously. Review every entry on every report for:

Incorrect personal information: Wrong address, misspelled name, or Social Security number errors that could be mixing your file with another person’s.

Accounts that are not yours: Identity theft or mixed files can result in negative accounts appearing on your report that belong to someone else. These are disputable and removable.

Incorrect payment history: A payment marked “30 days late” that you can prove was made on time. Creditors occasionally report inaccurately, and you have the right to dispute.

Duplicate collections: A single debt sometimes appears multiple times on a credit report as it is sold between collection agencies. Each duplication artificially inflates the apparent damage. Dispute duplicates.

Outdated negative information: Most negative items must be removed after 7 years (10 years for Chapter 7 bankruptcy). Items that have exceeded their legal reporting period should be disputed for removal.

How to dispute: File disputes directly with each bureau — Equifax at equifax.com, Experian at experian.com, TransUnion at transunion.com. Each bureau must investigate disputed items within 30 days and remove items they cannot verify. This process is free and does not require a credit repair company.

Timeline for error correction: 30 to 60 days from dispute filing to resolution for most items. Score improvements from error removal can range from negligible (if the error was minor) to 40 to 80 points (if an incorrect collection or judgment is removed).

Step 2: Address Negative Accounts Strategically

Not all negative items are equally damaging, and not all are equally addressable. Here is how to prioritize:

Collections Accounts

The current status question: A collection account that is currently active and being pursued by a collection agency is more damaging than one that is several years old. Recent collections — within the past two years — have the most significant score impact and are worth addressing first.

Pay for delete: Many collection agencies will agree to remove the collection notation from your credit report in exchange for payment of the debt. This agreement — a “pay for delete” letter — must be obtained in writing before you pay. A verbal agreement is unenforceable. Get it in writing, pay the agreed amount, then verify removal within 60 days.

Newer FICO models and paid collections: Under FICO 9 and FICO 10 (newer models), a paid collection account has significantly less impact on your score than an unpaid one. However, many mortgage lenders still use older FICO models (FICO 5, FICO 4, FICO 2) that do not fully ignore paid collections. For mortgage purposes, actually removing the account through a pay-for-delete arrangement is better than simply paying it.

The statute of limitations issue: Do not pay very old collection accounts without understanding the statute of limitations for the underlying debt in Missouri. Paying a debt that has passed the statute of limitations can in some cases restart the clock for legal collection — consult with a consumer debt attorney before paying debts older than four to five years.

Late Payments

Late payment notations (30-day, 60-day, 90-day) cannot be removed from your credit report if they are accurate — but their impact diminishes with age. A 30-day late from three years ago is significantly less damaging than one from six months ago. The most effective response to accurate late payments is time and consistent on-time behavior going forward.

Goodwill deletion requests: For long-term customers with a single late payment on an otherwise perfect history, some creditors will agree to remove the late notation as a goodwill gesture. Write or call the creditor’s customer service, explain the circumstances, and ask for goodwill deletion. This is not guaranteed — most creditors refuse — but the success rate for accounts with one isolated late payment and an otherwise strong history is approximately 20% to 30% in my experience.

Charge-Offs

A charge-off is a debt the creditor wrote off as uncollectible. It remains on your report for 7 years from the date of first delinquency regardless of whether you pay it. Paying a charge-off does not remove it — it changes the notation from “charged off” to “charged off — paid” or “settled,” which has marginally less impact but does not eliminate the negative entry.

For mortgage purposes, most conventional lenders require that charge-offs be paid before they will approve the loan. FHA guidelines are more nuanced — FHA does not automatically require payoff of all charge-offs, but individual lenders may impose overlay requirements.

Step 3: Reduce Credit Utilization — The Fastest Score Improvement Available

Credit utilization — the ratio of your current credit card balances to your credit card limits — accounts for 30% of your FICO score. It is the single most actionable short-term lever available to most people trying to improve their scores quickly.

The target: Keep utilization below 30% on each individual card and below 10% total for the maximum score benefit. Studies consistently show that borrowers with FICO scores above 750 carry total utilization below 10%.

The math: If you have a credit card with a $5,000 limit and a $3,500 balance, your utilization is 70% — a significant score suppressor. Paying that balance down to $500 (10% utilization) could improve your score by 40 to 80 points within 30 to 60 days of the lower balance being reported.

The fastest path: If you have savings, paying down credit card balances is likely the highest-return investment you can make in the months before applying for a mortgage. The score improvement translates to a lower interest rate that will save you tens of thousands of dollars over the loan term.

What not to do: Do not close credit card accounts to “clean up” your credit. Closing accounts reduces your total available credit, which increases your utilization ratio, which reduces your score. Leave existing accounts open even if you are not using them.

Step 4: Add Positive Credit History

If your credit profile is thin — few accounts, limited history — or if you are rebuilding after serious negative events, adding positive tradelines accelerates score improvement.

Secured credit cards: A secured card requires a cash deposit that becomes your credit limit. Used responsibly — small monthly purchases paid in full each month — a secured card reports 12 months of on-time payment history within a year. This positive history adds to your score even with the security deposit in place. Capital One, Discover, and several local credit unions offer secured cards specifically designed for credit building.

Credit-builder loans: Offered by many credit unions and community development financial institutions (CDFIs), credit-builder loans hold the loan proceeds in escrow while you make monthly payments. Each on-time payment is reported to the bureaus. After the loan term (typically 12 to 24 months), you receive the funds. The benefit is 12 to 24 months of reported installment loan payment history. Midland States Bank and Midwest BankCentre in the St. Louis area offer credit-builder products worth exploring.

Becoming an authorized user: If a family member or trusted friend has a credit card with a long positive history and low utilization, being added as an authorized user on that account causes the entire history of that account to appear on your credit report. This is one of the fastest ways to add positive history — the account’s age and payment record become yours immediately. You do not need to use the card or even have possession of it.

The Credit Repair Timeline: What to Expect

These timelines assume disciplined execution: all existing accounts paid on time, utilization actively managed, disputes filed and resolved, and no new negative items.

Credit Score Requirements for Every Major Loan Program

Understanding what each program requires gives you a specific target to work toward rather than a vague sense that your credit needs to improve.

FHA Loans — The Most Accessible Mainstream Program

Minimum score: 580 for 3.5% down payment. 500–579 for 10% down payment. Below 500: ineligible.

The practical reality: While FHA allows 580 scores, most lenders who originate FHA loans impose “overlays” — additional requirements above FHA’s minimums. Many FHA lenders in St. Louis require a minimum 600 to 620 score in practice, even though FHA allows 580. Shop multiple lenders. Some lenders actively work with 580 to 600 scores; others do not regardless of FHA guidelines.

Down payment: 3.5% with 580+ score. On a $195,000 home: $6,825.

Mortgage insurance: FHA requires an upfront MIP of 1.75% (typically financed into the loan) and an annual MIP of 0.55% to 1.05% depending on loan term. On a $195,000 FHA loan, the annual MIP is approximately $1,072/year ($89/month). This cost persists for the life of the loan for borrowers with less than 10% down — it does not automatically cancel as private mortgage insurance (PMI) does on conventional loans.

Debt-to-income limit: 43% back-end DTI standard; some lenders allow up to 50% with compensating factors.

Best for: First-time buyers with scores in the 580 to 660 range who have stable income and 3.5% down payment available.

VA Loans — The Best Program for Eligible Veterans

Minimum score: The VA itself has no minimum credit score requirement. Individual lenders impose their own minimums, typically 580 to 620 in practice.

Down payment: None required. 0% down.

Mortgage insurance: No PMI or MIP. This is the single most significant advantage of VA financing — eliminating the insurance cost that dramatically increases monthly payments on other low-down-payment programs.

Funding fee: 1.25% to 3.3% of the loan amount (varies by service history and whether this is a first use). Waived entirely for veterans with service-connected disabilities.

Best for: Any eligible veteran with a score above 580 should start with a VA loan evaluation before looking at any other program. The combination of no down payment and no mortgage insurance makes VA the most financially advantageous program available when the score qualifies.

In St. Louis: The St. Louis Veterans Service Center and the Truman VA Regional Office at 9700 Page Avenue are resources for veterans seeking loan guidance. Local VA-approved lenders include Veterans United (nationally prominent, St. Louis-based), Midwest BankCentre, and the military-focused divisions of regional banks.

Conventional Loans — The Credit Threshold Reality

Minimum score: 620 to qualify for most conventional loan programs. Below 620, conventional financing is not a realistic option through Fannie Mae or Freddie Mac guidelines.

The rate penalty for lower conventional scores: Unlike FHA, which charges the same MIP regardless of credit score within an eligibility band, conventional loans use risk-based pricing. Every 20-point credit score bracket affects the interest rate and loan-level price adjustments (LLPAs) charged by Fannie Mae and Freddie Mac.

Rate premium data for a 30-year conventional loan at $200,000:

• 760+ score: Base rate (e.g., 7.00%)
• 720–759: +0.25% (7.25%)
• 680–719: +0.50% (7.50%)
• 640–679: +1.00% (8.00%)
• 620–639: +1.50% to 2.00% (8.50–9.00%)

The difference between a 760 score and a 630 score on a conventional loan is approximately $200 to $350 per month in higher payment costs on a $200,000 loan. Over a 30-year term, that difference exceeds $72,000 to $126,000 in additional interest paid. This is the financial argument for credit repair before purchasing — the savings are enormous.

Best for: Borrowers with 680+ scores who have 5%+ down payment and want to avoid FHA’s lifetime MIP requirement.

USDA Loans — For Rural and Suburban Eligible Areas

Minimum score: 640 for streamlined approval; below 640 requires manual underwriting.

Down payment: None required.

Location restriction: Property must be in a USDA-eligible area. In the St. Louis metropolitan fringe — parts of Jefferson County, Franklin County, and portions of St. Charles County — USDA eligibility exists. Verify at eligibility.sc.egov.usda.gov.

Income limit: Household income cannot exceed 115% of the area median income.

Best for: Buyers in eligible rural/suburban areas with scores in the 600 to 640 range who do not qualify for VA benefits and cannot achieve the 3.5% FHA down payment.

Ways to Buy a House With Bad Credit — Options, Requirements, and Analysis

Option 1: FHA Loan at 500–579 Score With 10% Down

This is the lowest credit threshold for any standard institutional mortgage. The 10% down payment requirement at this score tier is a significant barrier — on a $195,000 home, 10% is $19,500 — but it is a legitimate path for buyers who have savings but damaged credit.

The honest analysis: At a sub-580 credit score, the combination of the higher down payment requirement, the elevated FHA MIP, and the higher rate (lenders impose risk-based pricing even within FHA’s framework) makes this an expensive borrowing scenario. The question is whether it is better than waiting to repair credit.

My assessment: Only pursue this route if you have a compelling reason not to wait — an imminent rent increase, a specific property opportunity, or housing instability. If you can manage 12 to 18 months of credit repair while maintaining stable housing, the improved score will significantly reduce your long-term borrowing cost.

Option 2: Land Contract (Contract for Deed)

A land contract is an agreement between a private seller and buyer where the seller finances the purchase directly. The buyer makes monthly payments to the seller, takes possession and use of the property, but does not receive legal title until the loan is paid in full or refinanced with institutional financing.

Requirements: Determined entirely by the private seller. No minimum credit score. No debt-to-income calculation by a lender. The seller evaluates the buyer on their own terms — typically income stability, employment verification, and down payment amount (typically 5% to 20%).

Advantages: Accessible to buyers who cannot qualify for any institutional financing. Faster closing than conventional loans. Negotiable terms.

Disadvantages: This is where I need to be blunt, because land contracts in Missouri have a complicated history.

The seller retains legal title throughout the contract term. If the buyer misses payments, the seller can pursue forfeiture — a process under RSMo Chapter 442 that, in Missouri, can result in the buyer losing the property and all payments made without the protections afforded in a standard foreclosure. Missouri’s land contract forfeiture process does not require the seller to return any equity the buyer has built up.

Additionally, land contracts are frequently used for distressed properties in St. Louis’s lower-income neighborhoods by sellers who have no intention of maintaining the property or providing clear title at the end of the contract. Buyers have sometimes paid on land contracts for years, only to discover that the seller’s mortgage was in default, that the title was encumbered, or that the seller never had the authority to convey the property.

The due diligence requirements if you pursue a land contract:

• Have a Missouri real estate attorney review the contract before signing
• Hire a title company to search the title and confirm the seller has clear, marketable title
• Insist on recording a memorandum of the land contract with the Recorder of Deeds to protect your interest
• Verify that any existing mortgage on the property does not have a due-on-sale clause that the land contract would trigger

My opinion: Land contracts can be legitimate tools for credit-impaired buyers when properly documented and entered with reputable sellers. In the St. Louis market specifically, be extremely cautious. The history of predatory land contract use in lower-income communities is real and documented. Hire an attorney.

Option 3: Rent-to-Own Agreements

A rent-to-own (lease-option) agreement gives the tenant the option to purchase the property at a predetermined price within a defined period, with a portion of the monthly rent credited toward the eventual purchase price or down payment.

Requirements: Set by the property owner. No institutional credit standard applies to the lease period. A minimum credit score for the eventual purchase (typically FHA’s 580) must be achievable by the option exercise date.

Advantages: Live in the home while building credit. Lock in a purchase price in an appreciating market. Some or all rent credits accumulate toward down payment.

Disadvantages: Option fees (typically 1% to 5% of purchase price) are paid upfront and are non-refundable if you do not exercise the option. Monthly rent on rent-to-own properties is typically higher than market rent — the premium funds the credit portion. If you fail to improve your credit sufficiently to secure financing by the option date, you lose the option fee and all rent credits.

The St. Louis market reality: Genuine rent-to-own properties from reputable sellers are rare in St. Louis. Many “rent-to-own” advertisements are either land contracts in disguise or are structured to make option exercise difficult. If pursuing this route, use an attorney and confirm the seller has clear title.

Option 4: Co-Borrower or Co-Signer

If you have a family member or trusted person with strong credit who is willing to co-sign or co-borrow on your mortgage, their credit profile is used in the application alongside yours. In most loan programs, both the primary borrower’s and co-borrower’s middle credit scores are pulled, and the lower of the two middle scores is used for qualification.

The practical benefit: A co-borrower with a 720 score cannot overcome your 520 score — the lender uses the lower of the two middle scores. However, a co-borrower can be tremendously helpful if your score is in the 580 to 620 range and their income and credit are sufficient to satisfy the DTI requirements.

The risks for the co-signer: They are fully liable for the loan. If you miss payments, their credit is damaged. If you default, the lender can pursue them for the full balance. Co-signing a mortgage is not a small favor — it is a substantial financial commitment that should not be entered lightly by either party.

Option 5: Non-Qualified Mortgage (Non-QM) Lenders

Non-QM lenders originate loans outside the Fannie Mae/Freddie Mac qualified mortgage framework, using alternative underwriting criteria that can include lower credit scores, higher DTI ratios, and alternative income documentation.

Credit requirements: Some Non-QM lenders originate loans for borrowers with scores as low as 500. Rates are higher than FHA — typically 8.0% to 11.0% in the current environment — and down payment requirements are typically 10% to 20%.

The honest analysis: Non-QM lending is a legitimate tool for specific situations — self-employed borrowers with strong income that does not show well on tax returns, investors using rental income that conventional underwriting discounts, and buyers with scores below 580 who have genuine reserves and stable income. For a first-time buyer with a 520 score and limited savings, the rates and terms of non-QM lending are genuinely punishing. The total cost of homeownership at a 9.5% non-QM rate versus waiting 18 months and qualifying at 7.0% FHA is significant.

Use non-QM if: You have a genuinely compelling reason to buy now, significant reserves (20%+ down payment), stable verifiable income, and a specific near-term plan to refinance into institutional financing after credit repair.

Should You Buy a House With Bad Credit? My Opinion

This is the question that deserves a direct answer rather than diplomatic equivocation. My honest answer is: it depends on the severity of the credit problem and your realistic timeline, but in most cases, the financially optimal choice is to repair credit before buying.

Here is the data that drives my opinion:

The Cost of Bad Credit Over a Mortgage Term

Scenario A: Buy at 580 score today with FHA financing at 6.75% on a $195,000 St. Louis home:

• Loan amount (with upfront MIP financed): $198,416
• Monthly PI: $1,287
• Monthly MIP: $91
• Total monthly cost: $1,378
• Total interest + MIP paid over 30 years: $254,000

Scenario B: Wait 18 months, improve to 660 score, buy at 6.25% FHA with the same purchasing power (price may have risen 3–5%):

• Purchase price: $203,000 (3% appreciation)
• Loan amount: $198,415
• Monthly PI: $1,221
• Monthly MIP: $88
• Total monthly cost: $1,309
• Total interest + MIP paid over 30 years: $237,000

Net advantage of waiting: Despite paying 18 months of rent (approximately $20,000 to $22,000 at St. Louis market rates), the savings on a 30-year mortgage term are $17,000 in reduced interest and MIP costs. If the score improvement reaches 680 and qualifies for conventional financing after 3 to 5 years of equity build, the lifetime savings are larger.

The counterargument: Appreciation during the waiting period works against you. If St. Louis homes appreciate 5% per year during your 18-month repair timeline, the $195,000 home costs $209,000 by the time you buy. That $14,000 in appreciation that you missed largely offsets the interest savings.

My actual opinion: In the St. Louis market — with its genuinely affordable entry-level prices and steady 3% to 6% annual appreciation — the window for effective credit repair without significant opportunity cost is approximately 6 to 18 months. If your credit is in the 580 to 620 range and can realistically reach 640 to 660 within 12 months through disciplined work, you should repair first. The combination of lower rates, conventional loan access within a few years, and avoidance of lifetime FHA MIP produces better lifetime financial outcomes.

If your credit is below 500 and genuine repair to FHA eligibility will take 3 or more years, the opportunity cost of waiting — three years of appreciation, three years of equity building you are not doing — tilts more toward finding a path to purchase sooner, even at higher cost.

The buyers who should not buy with bad credit:

• Anyone whose damaged credit reflects ongoing financial instability (no savings, current delinquencies, income volatility). Homeownership requires stable income and reserves that genuine financial instability does not provide.
• Anyone who is buying primarily because they want to “invest” and has not modeled the actual cash flow implications at the higher rate
• Anyone relying on a land contract with a seller they have not vetted through an attorney and title company

The buyers who may be justified in buying with bad credit:

• Veterans with VA eligibility who can access 0% down and no MIP at sub-620 scores
• Buyers using house hacking (FHA on a 2-4 unit) where rental income offsets the higher MIP cost
• Buyers who have experienced a one-time major negative event (foreclosure, bankruptcy from a specific crisis) but have stable income and are in a durable financial position now
• Buyers who can get below FHA’s floor through a land contract with a vetted, reputable seller and a Missouri real estate attorney involved
