Refinance Requirements: What Lenders Look For and How to Qualify

To refinance, most lenders require a credit score of about 620 or higher for conventional loans, a debt-to-income ratio generally at or below 43% to 50%, enough equity for the program you choose, and a recent history of on-time mortgage payments. FHA and VA programs are often more flexible, and streamline options may skip appraisals and income checks.

Exact requirements vary by lender and loan type. Below is what lenders typically look for and how to improve your odds.

Refinance requirements at a glance

These are common benchmarks, not guarantees. Individual lenders often add stricter rules, called overlays.

The core requirements: credit, DTI and equity

Three numbers drive most refinance decisions. Lenders feed them into automated underwriting systems and pricing grids, so small improvements in any one can change both approval and cost.

Credit score requirements for refinancing

Your credit score affects both approval and pricing. Conventional loans use risk-based pricing adjustments, so a lower score can mean a higher rate or more upfront fees even if you qualify.

Lenders also review your credit report for:

• Recent late mortgage payments, which weigh heavily
• Bankruptcy or foreclosure, which usually triggers waiting periods
• Collections and judgments, which may need to be resolved

Debt-to-income ratio (DTI)

DTI is your total monthly debt payments divided by gross monthly income. Lenders include the proposed new housing payment, including taxes, insurance and any HOA dues or mortgage insurance, plus recurring debts.

If your DTI is too high, paying off a small loan before applying, adding a co-borrower or choosing a lower loan amount can help. Some borrowers also refinance into a longer term to lower the payment, but weigh that against the extra interest over time. Lenders count only the minimum required payment on revolving accounts, so paying a card to zero before applying removes that payment from the calculation entirely.

Home equity and loan-to-value (LTV)

Loan-to-value is your new loan amount divided by the home's appraised value. Lower LTV means less risk for the lender and usually better pricing.

• At or below 80% LTV: conventional borrowers typically avoid PMI.
• Cash-out refinances: conventional and FHA loans commonly cap at 80% LTV.
• Underwater or low equity: full refinances are difficult, but FHA and VA streamlines generally do not need an appraisal.

If mortgage insurance is a major expense, our guide to refinancing to remove PMI compares refinancing with cancellation.

Seasoning and payment history

Seasoning means how long you must have had your current loan or owned the home before refinancing.

• Rate-and-term conventional: often possible soon after purchase, though some lenders require several months.
• Cash-out conventional: commonly about 12 months between the existing loan and the new one.
• FHA streamline: at least 210 days since closing and six payments made.
• VA IRRRL: the later of 210 days from your first payment due date or six consecutive payments.

Most programs also require that you have few or no late mortgage payments in the past 12 months.

Income, assets and property requirements

Lenders verify stable income, usually with pay stubs and two years of W-2s or tax returns, and may call your employer. Self-employed borrowers typically need two years of returns.

You may need reserves, meaning savings equal to a few months of mortgage payments, especially for second homes, investment properties or higher-risk files. The property must also meet the program's standards, and you need adequate homeowners insurance.

How to refinance with bad credit

Refinancing with a lower credit score is possible, but options narrow and costs rise. Realistic paths include:

1. FHA streamline refinance. If you have an FHA loan and a solid payment record, a non-credit-qualifying streamline may work.
2. VA IRRRL. Available to borrowers with an existing VA loan; lenders focus on payment history.
3. FHA rate-and-term refinance. Program minimums are lower than conventional, though lenders set their own floors.
4. Adding a co-borrower. A creditworthy co-borrower can strengthen the application, but they share responsibility for the debt.
5. Improving your credit first. Paying down cards and fixing errors for a few months may qualify you for noticeably better pricing.

Our guide to the FHA streamline refinance and VA IRRRL explains those programs in detail.

Before accepting any offer, confirm the savings outweigh the costs using the break-even method in when to refinance. Higher fees on a bad-credit refinance can erase much of the benefit.

Steps to take before you apply

• Pull your credit reports and fix errors.
• Calculate your DTI with the estimated new payment.
• Estimate your LTV using recent comparable sales.
• Gather two years of income documents and recent bank statements.
• Check your loan type on your statement to see whether a streamline program is available.

Taking these steps first helps you apply to the right program and avoid surprises in underwriting.

The bottom line

Lenders focus on credit, DTI, equity and payment history, and requirements differ by loan type. Check your credit reports, calculate your DTI and estimate your LTV before you apply. If your credit is weak, government streamline programs or a few months of credit improvement may be the smartest route.
