What this free online rental property refinance calculator does
Refinancing a rental property is not the same as refinancing your own home. The lender wants to know whether the property's income covers the loan, it usually allows a lower loan-to-value, and the rate is usually higher. This free online rental property refinance calculator works for rental, investment, second-home, condo and multifamily properties and tests all of it at once: the new payment, the cash flow, the debt service coverage ratio, the loan-to-value and the most cash you could take out.
Enter the value, the loan, the rent and the running costs, then the new rate, term, costs and the cash you want. The tool shows the new payment, how your cash flow changes, whether the loan passes common lender tests, and how much cash the loan-to-value and income limits allow. A rate table shows how the answer moves as the rate changes. Everything runs in your browser, so your figures stay private.
How to use the calculator
- Describe the property. Enter the value, the loan balance and the current rate and term.
- Enter the income. Use the monthly rent, a vacancy allowance, and the monthly costs of tax, insurance, repairs and management.
- Enter the refinance. Add the new rate, term and closing costs, and the cash you want, if any.
- Set the limits. Enter the maximum loan-to-value and the minimum DSCR your lender uses.
- Read the results. The tests show whether the loan fits, and the Cash-out limits tab shows the most cash you could take.
The tests lenders apply
| Test | Meaning | Typical expectation |
|---|---|---|
| Loan-to-value | New loan divided by property value | Often about 70% to 80% for investment properties |
| DSCR | Net operating income divided by the payment | Often about 1.0 to 1.25 or more |
| Cash flow | Income left after the payment | Positive is the aim |
| Reserves and credit | Savings and credit history | Set by the lender |
The tool tests the first three, which it can calculate from your inputs. The others depend on your personal finances and the lender, so ask for them early.
Worked example
An investor owns a property worth 400,000 with a loan of 240,000 at 6.5% and 24 years left. The rent is 3,200 a month with a 5% vacancy allowance and 1,000 of monthly costs, which gives net operating income of 2,040. The payment is about 1,650, so cash flow is about 390 and the DSCR is about 1.24. The investor wants 40,000 of cash out. A new 30-year loan at 7%, with 2.5% costs added to the loan, is about 287,000, which is 72% of the value. The payment is about 1,910, so cash flow falls to about 130 and the DSCR to about 1.07, which is below a 1.20 requirement. The loan-to-value passes, but the income test fails. The Cash-out limits tab shows that only about 9,100 fits under both limits.
This is a common pattern. The refinance looks fine on value, but the extra payment eats the cash flow. That is why the DSCR matters as much as the equity.
Taking cash out of a rental property
Cash-out refinancing turns equity into cash, and investors often use it for a down payment on another property, renovations or reserves. Two limits apply. The loan-to-value limit caps the loan at a share of the value. The income limit caps the payment at a share of the net operating income. Whichever is lower sets the cash you can take. A higher rate lowers the income limit, because the same payment covers a smaller loan.
Before you take cash out, think about what the money will earn compared with what it costs. The cost is the extra interest on the larger loan, the closing costs and the lower cash flow on the property. Use the tool to see each of these.
Tips
- Use realistic rent, not the best month, and include vacancy.
- Include all running costs, including a repair allowance.
- Compare lenders that specialise in investor loans, including DSCR lenders.
- Ask about prepayment penalties on investor loans.
- Keep enough reserves for vacancy and repairs.
Equity, risk and the cost of leverage
Equity in a rental property is not idle money, because it also protects you. A larger loan raises your monthly payment, lowers your cash flow and leaves less room if the property sits empty for a few months or needs a major repair. Lenders know this, which is why they cap the loan-to-value and require income to cover the payment with room to spare. Think of the DSCR as a safety margin for the lender and for you.
Before you take cash out, compare what the money will earn with what the borrowing costs. If the cash buys another property, the new income should be more than the extra interest. If it is spent on something that produces no income, the extra payment is a pure cost on a property that already carries debt. Also remember that a rate change can move the numbers: a loan that passes at 6.5% may fail at 7.5%, which is why the rate table is worth reading.
Finally, do not rely only on today's rent. Rents can fall, vacancy can rise and costs can climb, and the loan payment will not. Test a lower rent and a higher vacancy and see whether the property still carries the loan.
Common mistakes
- Using a main-home rate. Investment rates are higher.
- Ignoring vacancy and repairs.
- Taking the maximum cash out. It can leave thin cash flow.
- Forgetting closing costs.
- Assuming rents will rise. Plan with today's rent.

Privacy, accuracy and limits
The calculator runs entirely in your browser. The figures you enter are not sent to a server and are not stored, and reloading the page returns the example. The default values are illustrations. Taxes, reserves, credit and the lender's own rules are not included, and a lender decides whether to approve a loan. Confirm every number with a lender before you decide.
Frequently asked questions
Can I refinance a rental property?
Yes. You can refinance an investment property to lower the rate, change the term or take out cash. Lenders usually apply stricter rules than for a main home, such as a lower maximum loan-to-value, higher rates, larger reserves and a check on the property's income.
What is the maximum loan-to-value for an investment property refinance?
It varies by lender and loan type. Many investment loans allow around 75% of the value for a rate-and-term refinance, with a lower limit for cash-out, while limits for second homes and multifamily properties differ. Enter your lender's figure.
What is DSCR?
Debt service coverage ratio is the property's net operating income divided by its loan payments. A ratio of 1.2 means the income is 20% more than the payment. Many investor loans require a minimum such as 1.0 to 1.25, and some lenders base approval on it.
How is net operating income calculated?
It is the rent you collect, less vacancy and the running costs of the property, such as taxes, insurance, repairs and management. It does not include the loan payment. The tool takes rent, a vacancy allowance and monthly costs.
Can I take cash out of a rental property?
Often yes, up to the lender's loan-to-value limit and subject to the income test. The Cash-out limits tab shows the most you could take, whether the loan-to-value or the debt service coverage is the binding limit.
Why is my investment property rate higher?
Lenders usually price investment loans above main-home loans because they see more risk. Enter the rate you were quoted for the investment property, not a main-home rate.
Will refinancing improve my cash flow?
It can if the new payment is lower, for instance with a lower rate or a longer term. Taking out cash raises the payment and can reduce cash flow. The results show the cash flow before and after.
Should I roll the closing costs into the loan?
Rolling them in saves cash up front but raises the loan, the payment and the loan-to-value. Try both options in the tool.
What is a rate-and-term refinance?
It changes the rate or term without taking cash out. Set the cash-out amount to zero to see the break-even for a pure rate refinance.
What about a second home or a multifamily property?
Second homes often get more favourable terms than investment properties, while 2 to 4 unit properties and larger multifamily properties follow their own rules. Enter the limits that apply to yours.
Do I need reserves?
Lenders often ask for several months of payments in reserve, more for investment properties. The tool does not check reserves, so ask your lender.
Does the calculator account for taxes?
No. Tax treatment of interest, depreciation and cash-out proceeds depends on where you live and how you use the money. Ask a tax adviser.
What is a DSCR loan?
A loan where approval rests mainly on the property's income rather than your personal income. These loans often have higher rates and larger down payments. Use the DSCR figure and your quoted rate to test one.
How does this differ from the BRRRR calculator?
The BRRRR calculator models buying, renovating, renting and refinancing a deal. This tool starts from a property you already own and tests a refinance of it.
How accurate are the default figures?
They are examples only. Replace the value, rent, costs, rates and limits with your own, and use a lender's quote for the final decision.
Is my information private?
Yes. The calculator runs in your browser. Nothing you enter is sent to a server, saved or shared, and reloading the page resets it.
Is this rental property refinance calculator free?
Yes. It is a free online calculator with no sign-up, trial or limit. You can print or download the results.
