How refinancing works, at a glance
Refinancing means replacing your current loan with a new one — usually to get a better rate, change your monthly payment, shorten or lengthen your term, or access equity you've built up. The new loan pays off the old one, and you start fresh under new terms.
It isn't free to do. Refinancing comes with closing costs, so the real question is always whether what you save or gain outweighs what it costs to get there. That math looks different for a home than it does for a commercial property, which is why the two are covered separately below.
Residential refinancing
For a home you live in, refinancing usually falls into one of a few categories:
Rate-and-term
Replaces your loan to get a lower interest rate, a different term length, or both — without changing the loan balance.
Cash-out
Borrows against equity you've built, giving you cash at closing in exchange for a larger loan balance.
Streamline (FHA/VA)
A lighter-documentation refinance available on some government-backed loans, usually to lower rate or payment.
Cash-in
You pay down principal at closing — less common, but can help remove mortgage insurance or hit a better rate tier.
When it tends to make sense
- Current rates are meaningfully lower than your existing rate — often a full percentage point or more, though the right threshold depends on how long you plan to stay.
- You can recoup your closing costs through savings within a timeframe you're comfortable with (your "break-even point").
- Your credit and finances have improved since you took out your original loan, qualifying you for better terms.
- You need to remove a co-borrower, drop mortgage insurance, or restructure debt using home equity.
Qualifying factors lenders look at
- A credit score around 740 or higher typically qualifies you for a lender's best available pricing — lower scores usually still qualify, just at a higher rate.
- A loan-to-value (LTV) ratio of 80% or lower — meaning you owe 80% or less of your home's current value — generally lets you avoid paying private mortgage insurance (PMI).
Working out your break-even point
The formula is simple: divide your total closing costs by your monthly payment savings. The result is how many months it takes for the refinance to pay for itself.
$10,000 ÷ $327 ≈ 30.5 months to break even. If you plan to stay in the home longer than that, the refinance builds real savings. If you expect to move sooner, you'd likely lose money overall once costs are accounted for.
Commercial refinancing
Refinancing an investment or business property runs on different logic than a home loan. Lenders are less focused on your personal income and more focused on how the property itself performs.
What's different
- Debt service coverage (DSCR) — lenders check whether the property's income covers the new loan payment by a comfortable margin, not just your personal income.
- Shorter terms, balloon payments — commercial loans are often amortized over 20–25 years but due in full in 5–10, meaning you may need to refinance again before it's paid off.
- Prepayment penalties — many commercial loans charge a fee for paying off early, which can significantly affect whether refinancing is worth it right now.
- Appraisal-driven value — your ability to refinance often hinges on a commercial appraisal, which values the property based on its income, not just comparable sales.
When it tends to make sense
- Your balloon payment or term is coming due and needs to be replaced with new financing.
- The property's income has grown enough to qualify for better terms or a larger loan.
- You want to consolidate multiple properties or debts into a single loan.
- Rates have dropped enough to outweigh any prepayment penalty on your current loan.
Understanding DSCR in more depth
DSCR compares a property's net operating income (NOI) to its annual debt service (principal and interest). Lenders use it to gauge default risk, cap how much they'll lend, and set pricing — so where your property falls on this spectrum shapes almost every other term you're offered.
| DSCR range | Classification | What it typically means |
|---|---|---|
| 1.35x+ | Excellent / Prime |
|
| 1.25x – 1.34x | Good / Standard benchmark |
|
| 1.15x – 1.24x | Acceptable / Fair |
|
| 1.00x – 1.14x | Tight / Higher-risk |
|
| Below 1.00x | Deficit / Distressed |

What moves your target DSCR
- Property type
- Multifamily properties tend to see the lowest coverage thresholds (often 1.20x–1.25x on standard agency loans), reflecting steadier historical cash flow. Industrial and retail typically sit around the 1.25x–1.30x benchmark. Office and hospitality are viewed as higher-risk, so lenders often underwrite to 1.30x–1.50x or higher.
- Underwritten NOI vs. stated NOI
- Lenders rarely take your reported NOI at face value — they typically apply their own vacancy assumption (often around 5%), a management fee assumption (roughly 3–5%), and replacement reserves before calculating DSCR, which can bring the number down from what you calculated yourself.
- Lender type
- Banks and agencies (Fannie Mae/Freddie Mac) tend to hold a strict 1.25x+ standard but offer the lowest rates. SBA 7(a)/504 loans for owner-occupied commercial property typically look for a global DSCR of 1.15x–1.25x. Debt funds and private lenders can work with 1.00x–1.15x, in exchange for higher pricing.
The process, step by step
-
Get clear on your goal
Lower payment, shorter term, cash out, or removing someone from the loan — your goal shapes which type of refinance actually fits.
-
Check your numbers
Pull your credit, estimate your home or property's current value, and get a sense of your break-even point on closing costs.
-
Shop more than one lender
Rates and fees vary meaningfully between lenders for the same loan. Getting a few quotes on the same day makes them easier to compare fairly.
-
Compare APR, not just interest rate
The interest rate alone doesn't tell the full story. The APR (annual percentage rate) rolls in lender fees, discount points, and closing charges, giving you a more honest picture of a loan's true yearly cost — two loans with the same rate can have very different APRs.
-
Lock your rate and complete underwriting
Once you choose a lender, you'll typically lock your rate for 30 to 60 days to protect against market swings while they verify your finances and, for commercial loans, the property's income.
-
Close and confirm the payoff
At closing, your new loan pays off the old one. Confirm your old loan shows as paid in full and your new payment schedule is what you expected.
What you'll typically need
Requirements vary by lender and loan type, but most refinances ask for some version of the following:
- Recent pay stubs or, for self-employed/business owners, recent tax returns and profit-and-loss statements
- Bank and asset statements from the last two to three months
- Your current mortgage or loan statement
- Proof of homeowners insurance (or commercial property insurance)
- Government-issued ID
- For commercial refinances: current rent roll and property income/expense statements
Quick glossary
- Break-even point
- How long it takes for your monthly savings to cover the closing costs you paid to refinance.
- Equity
- The difference between what your property is worth and what you still owe on it.
- DSCR (Debt Service Coverage Ratio)
- A measure lenders use on commercial loans, comparing a property's income to its loan payment.
- Amortization
- The schedule by which a loan is paid down over time through regular payments.
- Balloon payment
- A large final payment due at the end of a loan term that is shorter than its amortization schedule — common in commercial lending.
- Loan estimate
- A standardized document lenders provide showing a loan's rate, fees, and terms, making it easier to compare offers.
- APR (Annual Percentage Rate)
- A loan's yearly cost including fees and points, not just the interest rate — useful for comparing offers apples-to-apples.
- Loan-to-value (LTV)
- The percentage of a property's value that's still owed on its loan. Lower LTV generally means better terms and, on residential loans, no PMI requirement below 80%.
