If you bought your home a while back and you have been paying down the balance steadily, you have probably wondered whether a conventional refinance is worth the paperwork. The short answer is that it depends on your numbers, not the headlines. This guide walks through the actual requirements lenders look at so you can check your eligibility before you spend an afternoon gathering documents.
A conventional refinance replaces your current mortgage with a new conventional loan, one that is not backed by a government agency. People do it to lower a monthly payment, switch from an adjustable rate to a fixed one, shorten the term, drop mortgage insurance, or pull cash out of the equity they have built. Each of those goals carries slightly different requirements, and knowing them up front saves you time.
What a conventional refinance actually checks
Lenders evaluate four things when you apply for a conventional refinance: your credit, your debt load relative to income, the equity in your home, and your ability to document income. None of these are mysteries. You can estimate where you stand on each one today, at your kitchen table, before anyone runs a credit report.
The federal Consumer Financial Protection Bureau keeps a plain-language guide to the refinance decision itself, including how to weigh closing costs against monthly savings. It is a useful starting point and worth reading once before you talk to anyone. You can find it at consumerfinance.gov.
Credit score expectations
Most conventional refinance programs look for a credit score starting around 620. That is the floor, not the target. A score in the higher ranges usually opens up more options and better pricing, and many readers in their fifties and sixties who have carried a mortgage for years already sit comfortably above that line.
Your score interacts with the other factors. If you are borrowing a larger share of your home's value or carrying more monthly debt, lenders tend to want a stronger score to balance the file. If your score sits around 700 and your other numbers are reasonable, you are usually in solid shape for a rate-and-term conventional refinance.
If your credit has a few rough spots, that does not automatically end the conversation. It changes which loan structure fits. A GoodLoan loan officer can read your full picture and tell you plainly whether waiting a few months to clean up a report would change your options. We say no a lot, and we would rather tell you to wait than push you into something that does not help.
Debt-to-income ratio
Your debt-to-income ratio, or DTI, is the share of your gross monthly income that goes toward debt payments, including the new mortgage. Conventional refinance guidelines generally favor a DTI at or below roughly 43 percent, and a lower number gives you more room. Some files qualify higher when the rest of the application is strong, but 43 percent is a reasonable line to measure yourself against.
Here is how to check it yourself. Add up your monthly debt payments: the proposed new mortgage payment, car loans, minimum credit card payments, student loans, and any other recurring obligations. Divide that total by your gross monthly income, before taxes. If you land near or under 43 percent, your DTI is likely workable. If you are above it, paying down a card or two before applying can move the number meaningfully.
Equity and loan-to-value
Equity is the part of your home you actually own, and lenders measure it through loan-to-value, or LTV. LTV is your loan balance divided by the home's appraised value. A rate-and-term conventional refinance can often go up to 95 percent LTV, meaning you need only about 5 percent equity, though more equity generally improves your terms.
A cash-out conventional refinance is stricter. For a single-family primary residence, the standard maximum is 80 percent LTV, so you keep at least 20 percent equity in the home after taking cash. That 80 percent line matters for another reason worth understanding.
The 80 percent line and mortgage insurance
If you currently pay private mortgage insurance, a refinance can be the moment you stop. Under the federal Homeowners Protection Act, you have the right to request cancellation of PMI once your balance reaches 80 percent of the original value of the home, and your servicer must automatically end it at 78 percent. For a loan you already hold, "original value" generally means the value when you took that loan. These rules are explained directly by the CFPB at consumerfinance.gov.
When you refinance into a new conventional loan and your new balance is at or below 80 percent of the current appraised value, the new loan typically carries no PMI at all. For homeowners whose property has gained value, this is sometimes the single largest reason a conventional refinance pays off, separate from any rate question.
Income and employment documentation
Lenders need to confirm you can repay the new loan. For most salaried borrowers that means recent pay stubs, W-2 forms covering the past two years, and sometimes a verbal or written confirmation from your employer. If you are self-employed, expect to provide two years of tax returns and possibly profit-and-loss records.
Retirement changes the documents, not your eligibility. Social Security award letters, pension statements, and recent statements from retirement accounts can all establish qualifying income. If you are retired or partly retired, a loan officer can tell you which combination of these documents builds the strongest file. Plenty of people assume retirement disqualifies them, and it usually does not.
The appraisal and seasoning
Most conventional refinances require an appraisal to set the home's current value, which then drives your LTV. In some cases an appraisal waiver is available, but plan for one. The appraisal protects you too, because it confirms how much equity you genuinely have.
Seasoning refers to how long you must hold your current loan before refinancing. Rate-and-term conventional refinances often have little or no seasoning requirement, while cash-out refinances commonly ask that you have owned the home for at least six months. If you bought or last refinanced recently, this is worth confirming before you apply.
Rate-and-term versus cash-out
A rate-and-term conventional refinance changes your interest rate, your loan term, or both, without increasing the loan balance beyond closing costs. It is the path most people take to lower a payment, move to a fixed rate, or shorten a 30-year loan to something shorter so they own the home sooner.
A cash-out conventional refinance replaces your loan with a larger one and gives you the difference in cash. Homeowners use it to consolidate higher-cost debt, fund a home repair, or cover a planned expense. The CFPB has studied how borrowers use cash-out refinances and how it affects their broader finances, and its research is available at consumerfinance.gov. Cash-out carries the stricter 80 percent LTV cap noted above and usually slightly different pricing, so the math deserves a careful look.
A note for veterans
About half the homeowners we work with have served. If you have VA loan eligibility, a conventional refinance is not your only road, and in some cases a VA-backed option may fit your situation better. That benefit was earned through your service, and it is worth putting on the table alongside the conventional path so you can compare honestly. The Department of Veterans Affairs explains refinance options at va.gov, and the CFPB and VA have published a joint caution about refinance offers that sound too good to be true, available at consumerfinance.gov.
How rates fit into the decision, without the noise
Interest rate matters, but it is one input, not the whole answer. The real question is total cost over the time you plan to keep the loan. A lower rate that comes with high fees can cost more than a slightly higher rate with lower fees, depending on how long you stay.
The way to cut through it is break-even math with your own numbers. Take the total cost to close the refinance and divide it by the monthly amount you would save. The result is the number of months it takes to recover the cost. If you plan to stay in the home well past that point, the refinance tends to make sense. If you might move before then, it may not. This is arithmetic you can do yourself, and a loan officer should be willing to walk through it with you line by line rather than quoting a single number.
A possible tax angle
For some homeowners, mortgage interest is deductible if you itemize, and the rules around refinanced debt and any cash taken out have specific conditions. This is tax territory, not loan advice, so the authoritative source is the IRS. Publication 936 covers the home mortgage interest deduction in detail at irs.gov. Your tax preparer can tell you how it applies to your situation.
Your first step
Checking eligibility for a conventional refinance does not require an application or a credit pull. Start with the four numbers above: your approximate credit score, your DTI, your estimated equity, and a sense of your income documents. Once you have those, a short conversation tells you whether the timing works and which structure fits.
When you are ready, you can speak with a GoodLoan loan officer who will look at the full financial picture with you, fees and timeline included, and tell you honestly whether a refinance helps. GoodLoan is a licensed mortgage lender (NMLS #) and VA-approved. There is no obligation in asking, and a clear answer beats a guess.
Frequently asked questions
What credit score do I need for a conventional refinance?
Most conventional refinance programs start around a 620 score, with stronger scores generally opening more options. Your score works together with your equity and debt load, so a borrower near 700 with reasonable other numbers is usually in good shape. A loan officer can tell you whether your specific profile qualifies today.
How much equity do I need to refinance?
A rate-and-term conventional refinance can often go up to about 95 percent LTV, so roughly 5 percent equity. A cash-out conventional refinance on a primary home is capped at 80 percent LTV, meaning you keep at least 20 percent equity after taking cash.
Can I drop mortgage insurance by refinancing?
Often, yes. If your new conventional loan balance is at or below 80 percent of your home's current appraised value, the new loan typically carries no PMI. The CFPB explains your separate cancellation rights on an existing loan at consumerfinance.gov.
Do I have to get an appraisal?
Most conventional refinances require an appraisal to confirm your home's current value, which sets your LTV. An appraisal waiver is available in some cases, but it is wise to plan for one.
How do I know if refinancing is actually worth it?
Use break-even math with your own numbers: divide the total cost to close by your expected monthly savings to see how many months it takes to recover the cost. If you plan to keep the home past that point, a conventional refinance often makes sense. A GoodLoan loan officer can work the numbers with you.
