Refinancing With Bad Credit: Your Options and What They Actually Cost

A credit score below 620 significantly narrows your refinancing options — but it doesn't eliminate them. Whether or not a refinance makes sense with bad credit depends on which loan type you currently have, how much room is in your budget, and whether the credit cost of refinancing now outweighs the benefit of waiting.

Here's an honest look at the options.

What "Bad Credit" Means for a Mortgage Refinance

Credit score thresholds for mortgage refinancing vary by loan type and lender:

Conventional refinancing through Fannie Mae or Freddie Mac typically requires a minimum 620 credit score, though most competitive lenders want 680+. Below 620, the pool of conventional lenders shrinks dramatically and the rate premiums add up fast.

Government-Backed Streamline Programs: Your Best Option With Bad Credit

If you already have a government-backed mortgage, you may qualify for a streamline refinance that sidesteps the credit qualification problem entirely.

FHA Streamline (Non-Credit-Qualifying)

If your current mortgage is FHA-insured, you may qualify for an FHA Streamline without a credit check.

The non-credit-qualifying option is available when:

• Your current loan is FHA and at least 210 days old
• You've made at least 6 consecutive on-time payments
• You have no late payments in the last 12 months (some lenders accept 1 late payment, others don't)
• The combined interest rate drops by at least 0.5 percentage points

What matters here is your payment history, not your FICO score. A homeowner with a 560 credit score who has paid their FHA mortgage on time for 18 months is eligible for this program.

The trade-off: closing costs must be paid upfront (or lender-credited at a higher rate) since you can't roll them into the loan balance on a non-credit-qualifying streamline.

VA IRRRL (Interest Rate Reduction Refinance Loan)

For eligible veterans and service members with existing VA loans, the IRRRL program has minimal credit requirements. Most VA lenders process IRRRLs based on payment history rather than credit score, and some don't set a minimum score at all.

Requirements are straightforward:

• Existing loan must be VA-backed
• At least 210 days from first payment due date
• At least 6 consecutive payments made
• Rate must drop by at least 0.5% (fixed-to-fixed)

The VA Funding Fee for an IRRRL is 0.5% — much lower than the 1.75% upfront MIP on an FHA Streamline. If you have a VA loan, this is the most cost-efficient path regardless of credit score.

USDA Streamlined Assist

For USDA Section 502 loan holders in rural areas, the Streamlined Assist program requires 12 months of on-time payments and a $50+ reduction in the monthly payment (including taxes and insurance). Credit score is not explicitly required for qualification.

Conventional Options Below 620: Limited but Not Zero

A few specialized conventional programs exist for lower-credit refinancing:

Portfolio lenders: Banks and credit unions that hold loans on their own balance sheets (rather than selling to Fannie/Freddie) can write their own underwriting rules. Some will refinance at 580–619 if you have strong compensating factors — significant equity, stable income, low debt-to-income ratio.

Hard money refinancing: For investment properties (not primary residences), hard money lenders focus on asset value rather than credit. Interest rates are significantly higher (8–13%), but accessible if you need to refinance an investment property and can't qualify otherwise.

Non-QM loans: Non-Qualified Mortgage lenders serve borrowers who don't fit standard underwriting boxes. Lower credit thresholds are possible, but rates are substantially higher than conventional lending.

The Rate Cost of Bad Credit

Rate penalties for lower credit scores on conventional loans are significant. Loan-Level Price Adjustments (LLPAs) — fees built into the interest rate by Fannie Mae and Freddie Mac — increase substantially below 680:

A borrower with a 620 score refinancing $350,000 at 80% LTV pays roughly 2.0–2.5% in additional pricing compared to a 740+ borrower. On a $350,000 loan, that's $7,000–$8,750 in additional costs — typically expressed as a rate that's 0.5–0.75% higher than what a strong-credit borrower receives.

This narrows the interest savings from refinancing considerably. If you're refinancing to capture a 0.5% rate drop and the credit penalty adds 0.5% back into your rate, you've effectively broken even on the rate without capturing any benefit.

Refinancing vs. Waiting to Rebuild Credit

The break-even calculation changes meaningfully when you factor in the credit cost. Consider:

Scenario: Current rate 7.5%, refinancing target 7.0% (0.5% rate drop). Score is 610.

With the credit penalty, actual rate available at 610 is likely 7.0–7.25% — barely an improvement. Closing costs of $6,000–$8,000 produce a break-even of 50+ months at minimal monthly savings.

Alternative: 12 months of on-time payments, paying down credit card balances to below 30% utilization, and disputing any errors on credit reports can plausibly move a 610 score to 660–680. At 680, the credit penalty drops dramatically and you access a materially better rate — potentially capturing a 1.0%+ reduction rather than a 0.25% reduction.

The math often favors waiting and rebuilding credit over refinancing now at a penalized rate. The exception is if your financial situation is strained and a lower payment provides essential liquidity relief — in which case even a modest rate reduction is worth the cost.

Credit Unions and Community Banks

If you're below 620, credit unions and community banks are worth approaching before larger national lenders. They maintain their own underwriting standards, often consider the full relationship (existing accounts, employment history, local ties), and sometimes have more flexibility on credit score minimums.

Mortgage brokers who specialize in bad-credit scenarios can also surface options from wholesale lenders that aren't visible through direct-to-consumer channels.

Practical Steps Before Applying

Before you approach any lender with sub-620 credit:

1. Pull your free credit reports from annualcreditreport.com and dispute any inaccuracies. Errors are common and a dispute can move a score 20–40 points if resolved favorably.
2. Check your credit utilization. Paying down revolving credit card balances to below 30% of credit limits often produces the fastest score improvement.
3. Avoid new credit applications for 3–6 months before applying. New inquiries lower scores temporarily.
4. Calculate whether the current refinance math actually works given the rate you'll realistically receive. The Refinancing Decision Worksheet lets you input the actual rate you've been quoted and calculates a true break-even — so you can see whether the transaction is worth doing now or whether waiting makes more financial sense.
