Credit Repair Before Buying a House: A Mortgage Pro's Playbook

I've been a licensed mortgage professional for years, and I can tell you with certainty: your credit score is the single most important variable in whether you can buy a home and what rate you'll pay when you do. I've watched people lose their dream home because they came to the table with a 578 instead of a 580. I've watched borrowers pay an extra $250/month — for 30 years — because they didn't know how to raise their score from 640 to 720 before applying.

This is the playbook I wish every pre-buyer had. If you're planning to purchase a home in the next 6-24 months, start here.

Minimum Credit Score Requirements by Loan Type

Let's start with the hard numbers. These are the minimum credit scores required for each major loan type:

FHA Loans (Federal Housing Administration)

• 580+: Eligible for 3.5% down payment — FHA's standard program
• 500-579: May qualify with 10% down payment — limited lenders, harder approval
• Below 500: Not eligible for FHA financing

FHA loans are government-backed and have more lenient overall credit requirements. They also allow higher debt-to-income ratios and are more forgiving of recent credit events like collections and late payments — though lenders still scrutinize your full credit history.

Conventional Loans (Fannie Mae / Freddie Mac)

• 620+: Minimum to qualify for standard conventional programs
• 640+: Required for some programs with higher DTI
• 680+: Better pricing tier begins
• 740+: Best rate pricing
• 760+: Maximum tier — optimum pricing across all programs

Conventional loans have stricter credit standards than FHA but lower ongoing mortgage insurance costs. For buyers who can reach 620, they're worth considering. For buyers who can reach 680+, they're often the better choice.

VA Loans (Department of Veterans Affairs)

• No official VA minimum — The VA doesn't set a credit score floor
• Most VA lenders require 580-620 — These are lender overlays, not VA requirements
• Some lenders go to 550 or lower — For highly qualified Veterans with strong residual income

VA loans are the most generous program available to eligible Veterans. No down payment required, no private mortgage insurance, and competitive rates. Even with credit challenges, many Veterans can qualify with careful lender selection.

USDA Loans (Rural Housing Program)

• 640+: Standard requirement for automated underwriting
• Below 640: May require manual underwriting with stronger compensating factors

USDA loans offer 100% financing for eligible rural areas. Credit requirements are stricter than FHA but similar to conventional.

Non-QM / DSCR Loans

• 600-640+: Typical minimums vary by product and lender
• These programs exist outside conventional guidelines and are more flexible overall
• Higher rates than conventional/government programs

What Score Should You Actually Target?

Minimums get you in the door. Targets get you the best deal. Here's what I tell pre-buyers:

• Below 580: Must reach 580 (FHA minimum). Priority: any path to 580.
• 580-619: FHA-eligible now, but target 620 for conventional access and better pricing.
• 620-679: Conventional-eligible but higher PMI and rates. Target 680 for meaningful improvement.
• 680-719: Good. Target 720+ for better rate tiers.
• 720-739: Very good. Push to 740 for maximum conventional pricing.
• 740+: Optimal. Focus on maintaining, not improving.

The biggest dollar-impact thresholds are at 580, 620, and 740. If you're near any of these, a targeted push to cross the threshold is worth significant effort.

What Mortgage Underwriters Look At Beyond the Score

Your credit score is a summary, but underwriters read the full report. Specific items that trigger scrutiny:

Open Collections

Conventional guidelines (Fannie Mae/Freddie Mac) may require that collection accounts be paid before closing. FHA is more flexible — medical collections are generally exempt, and non-medical collections under $2,000 are often overlooked. But individual lenders may add their own overlays (stricter requirements than program guidelines).

Recent Late Payments

Late payments in the 12-24 months before application are red flags for underwriters. A late payment from 4 years ago matters much less than one from 8 months ago. If you have recent lates, 12-24 months of perfect payment history before applying will significantly improve your approval odds.

Charge-Offs

Open charge-offs are major derogatory items. Most conventional lenders require them to be addressed. FHA allows more flexibility but will scrutinize them.

Student Loans

Student loans affect your debt-to-income ratio. Deferred student loans are still counted against DTI in most calculations. IBR (income-based repayment) payments are generally counted as-is.

Judgments

Court judgments must typically be paid before closing. They show up in public records and are automatic flags for underwriters.

The Playbook: Getting from 550 to 620 to 720

Stage 1: Getting to 580 (FHA Minimum)

From a score in the 520-560 range, your priorities:

1. Dispute every inaccuracy on all three reports — errors could be worth 20-60 points
2. Get credit utilization below 30% on all cards — could add 20-40 points
3. Begin disputing or negotiating collections — even removing one can add 30+ points
4. Add a positive account (secured card) if your file is thin
5. Set up autopay everywhere — no new late payments

Timeline: 3-6 months of aggressive action typically gets most people from 550 to 580+.

Stage 2: Getting to 620 (Conventional Minimum)

From 580-615, you're likely dealing with a combination of:

• Remaining collections or charge-offs
• Utilization still above 30%
• Limited positive history

Continue disputing, continue reducing utilization, and let 12 months of on-time payments build. Timeline: 3-9 months from 580 to 620.

Stage 3: Getting from 620 to 720+

This stage is about removing the last major negatives and optimizing:

• Remove any remaining collections (goodwill letters, pay-for-delete)
• Get utilization below 10%
• 24 months of clean payment history
• Avoid hard inquiries for 6+ months before application

Timeline: 6-18 months from 620 to 720.

Timing Your Mortgage Application

A critical mortgage pro tip: don't apply until your credit is ready.

• Don't apply for new credit 6-12 months before applying for a mortgage. Hard inquiries drop your score and flag you as someone shopping for credit.
• Don't close accounts before applying. Reduces available credit and credit history. Wait until after closing.
• Don't make large purchases on credit before closing. Increases utilization and DTI mid-application.
• Don't change jobs if possible. Employment stability is a key underwriting factor.
• Do get a pre-approval check before formally applying. A good loan officer can pull your credit and tell you exactly what to fix before your full application.

How I Help Pre-Buyers Prepare

When I work with buyers who aren't ready yet, I do what's called a "credit analysis" — I pull their reports, identify exactly what's holding them back, and give them a specific action plan. Then we schedule a follow-up 6 months later.

The Credit Fix Kit is essentially the DIY version of that process: it walks you through pulling your reports, identifying what matters for mortgage qualification specifically, and gives you all the dispute letters and strategies to fix it. Many of the borrowers I've sent to agencies could have done this themselves — and saved the $1,500 they spent.

The Bottom Line: Don't Shortcut This

Buying a home is likely the largest financial transaction of your life. Spending 6-12 months preparing your credit before applying — rather than applying now with a damaged profile — can save you $50,000-$150,000 over the life of your mortgage in lower interest rates alone.

Take the time. Do it right. Your future self will thank you at closing.
