Bad credit does not shut you out of a mortgage. It changes the price you pay for one. That distinction matters, because most advice stops at “fix your score first” and never explains what to do if you can’t wait two years.
People buy homes with scores in the 500s every month. They use government-backed loans, bigger down payments, and compensating factors that convince an underwriter their credit history is a story with an ending rather than a pattern. Here’s how the process actually works, and what it costs.
What “Bad Credit” Means to an Underwriter
FICO scores under 580 get labelled poor. Scores from 580 to 669 are fair. Those labels describe statistical risk, and they function as a pricing dial more than a gate.
Each loan program sets its own floor, and the spread is wider than most people expect:
- FHA loans: 580 minimum for 3.5% down. Between 500 and 579 you can still qualify, but you’ll need 10% down.
- VA loans: No official floor from the VA. Individual lenders usually want 580 to 620.
- USDA loans: 640 for automated approval. Below that, an underwriter reviews the file by hand.
- Conventional loans: 620 is the wall, and pricing climbs sharply under 700.
The lowest number on that list is 500. If you assumed a 560 score made you unqualified, you were reading the wrong map.
The Levers That Matter More Than Your Score
Underwriters don’t read your credit report in isolation. They read it alongside everything else in the file, and a strong enough package can offset a weak score.
Down payment
Money down reduces the lender’s exposure, and it does more than any other single factor to soften a low score. Going from 3.5% to 10% down on a $300,000 house means bringing $31,500 instead of $10,500. In exchange, you may shave half a point off the rate and drop mortgage insurance sooner. If you’re still building that cushion, it’s worth mapping out how much you should save before buying a home before you start touring listings.
Debt-to-income ratio
Take your total monthly debt payments, divide by gross monthly income. Most programs cap you between 43% and 50%. A 620 score at 34% DTI is a far easier approval than a 620 at 49%. Paying off a $250 car payment can matter more than gaining 20 credit score points.
Compensating factors
Automated underwriting issues the first verdict. A human can override it. What sways that human:
- Twelve months of on-time rent, verified by cancelled checks or a landlord letter
- Six months of cash reserves left over after closing
- Two years with the same employer in the same field
- A written, documented explanation for each derogatory mark
Which Loan Programs Say Yes
FHA is the default answer for most buyers with damaged credit, and for good reason. The score floor is low, the down payment is small, and sellers can contribute up to 6% toward your closing costs. The trade-off is mortgage insurance: 1.75% upfront plus an annual premium around 0.55% of the loan balance.
VA loans beat FHA on nearly every front if you’re eligible, because there’s no monthly mortgage insurance premium at all. USDA loans offer 100% financing in rural areas. If you’re sitting at a 580, there’s a step-by-step playbook for buying with a 580 credit score that breaks the numbers down month by month.
Outside those three, options narrow. Non-QM lenders will look at bank statements instead of tax returns. Some sellers will carry a second mortgage. Co-signers only help if their income and debts are counted on the loan, which means their DTI has to absorb yours too.
What Bad Credit Costs You in Real Dollars
Take a $280,000 loan on a 30-year fixed. A 760 score might get 6.25%. A 580 score might get 7.5%. That 1.25-point gap sounds modest until you run it:
- At 6.25%: $1,724 per month in principal and interest
- At 7.5%: $1,958 per month
- Difference: $234 monthly, roughly $84,000 across the full term
Add FHA mortgage insurance and the real spread widens further. This is the part most guides skip, and it should shape your decision. Before you sign anything, understand what actually works and what quietly costs you money when you buy with damaged credit.
The 12-Month Sprint That Moves the Needle Fastest
Credit repair is slow. Credit improvement is faster than people think. Most of the damage that matters sits in two places: utilization and recent delinquencies.
Card balances are the quickest lever. Utilization is measured against your limit, and scoring models reward you for dropping under 30% and reward you more under 10%. If you carry $4,800 on a $6,000 limit, that’s 80% utilization. Getting it to $600 is worth more than any credit repair service will deliver in the same window.
- Dispute factual errors. The FTC has found roughly one in five credit reports contains a mistake.
- Stop applying for new credit. Every hard inquiry costs points and signals risk.
- Keep old accounts open. Length of history is 15% of your score.
- Ask about rapid rescore. A broker can push updated balances to the bureaus in days, not weeks.
Timing the Purchase Around Rates, Not Just Your Score
A 12-month wait that lifts you from 580 to 660 saves five figures over 30 years. A 12-month wait that overlaps with rates climbing two points erases that gain entirely. Both variables move, and they don’t move together.
So run both scenarios side by side. A rate-proof plan for buying when interest rates rise shows you what a rate lock, a temporary buydown, or a slightly smaller loan amount does to the math. Sometimes buying now at a higher rate and refinancing in two years beats waiting.
Getting Pre-Approved With a Weak File
Pre-approval is where theory meets reality. Bring the full package: two years of tax returns, 30 days of pay stubs, three months of bank statements, and a letter of explanation for every negative item on your report.
The letter matters. “I was laid off in March 2023 and fell behind on two cards. I’ve been employed since June 2023, and both accounts are current” is a sentence an underwriter can work with. Silence isn’t. It also helps to know upfront whether you can buy a house with bad credit and what the full cost picture looks like before you sit across from a loan officer.
Mistakes That Sink Low-Score Buyers
- Opening a store card for furniture. A new account before closing can kill the deal at the final credit pull.
- Changing jobs mid-process. Lenders verify employment again days before closing.
- Moving money without a paper trail. Large unexplained deposits get flagged fast.
- Obsessing over the rate. Points, origination fees, and mortgage insurance often dwarf the headline number.
When Waiting Genuinely Is the Better Move
Run one comparison. Say your rent is $2,100 and buying today would cost $2,350 all-in. Waiting a year costs you $3,000 in extra housing expense. If that year drops your rate by 1.25 points, you save about $84,000 over the life of the loan plus $234 every month.
Three thousand against eighty-four thousand isn’t a close call. If a year of credit work gets you a materially better rate, wait.
If it doesn’t, or if your rent already sits close to what a mortgage would cost, the math flips. The break-even usually lands between 8 and 18 months of payment difference, and it depends entirely on your numbers rather than a general rule.
Start by pulling all three credit reports and your FICO scores. Then call two lenders and ask one question: “What score do I need to reach the next pricing tier, and how much would that save me per month?” Their answer tells you whether to buy this spring or next.
