Two landlords own the same $420,000 rental carrying the same $240,000 mortgage at the same 4.75 percent rate. One refinances and pulls $68,700 of equity out. The other leaves the loan alone. Five years later one of them is meaningfully better off, and which one it is has very little to do with the refinance and almost everything to do with what the cash did next.
This post gives you the arithmetic for deciding whether to refinance a rental property in 2026 or hold the loan you have. You will get the break-even yield formula, a full worked example using current rates and the loan-to-value caps investors actually face, and six mistakes that make the decision look better on paper than it is.
What refinancing a rental property actually does
There are two transactions wearing the same name, and they answer different questions.
A rate and term refinance replaces your loan with a new one at roughly the same balance. You are buying a lower payment, a shorter term, or both. It only works when the new rate is meaningfully below the old one.
A cash-out refinance replaces your loan with a larger one and hands you the difference. You are not buying a lower payment. You are buying liquidity, and the price is permanently higher debt service on the property.
Which one is on the table in 2026 is settled by where rates sit. The 30-year fixed averaged 7.24 percent in Freddie Mac’s survey for the week of October 29, 2026, and that survey tracks owner-occupied conforming loans, so treat it as a floor rather than a quote on an investment property. Most rental loans written between 2020 and 2022 carry a 3 or a 4 in front of the decimal. If that describes your loan, the rate and term refinance is not a decision, and the only live question is whether to pull equity.
The framework: what the pulled equity has to earn
A cash-out refinance is neither free money nor a cost. It is a trade at a known price, and the only question is whether the cash you receive can beat that price. One number answers it:
Break-Even Yield = Annual Payment Increase ÷ Net Cash Received
Net cash received. The new loan amount minus the payoff on the old loan, minus closing costs, lender fees, and prepaid items. This is the money that actually lands in your account, not the headline loan amount.
Annual payment increase. New principal and interest for twelve months minus old principal and interest for twelve months. Use principal and interest only. Taxes and insurance do not change because you refinanced, so including them distorts the comparison.
The result. The pre-tax cash return the money has to earn, every year, before the refinance adds a single dollar to your position. Below that number you are moving backward with more risk than you had before.
Worked example: a $420,000 single-family rental
The inputs:
- Current value: $420,000
- Current loan balance: $240,000, which is a 57.1 percent loan-to-value
- Current rate: 4.75 percent, 300 months remaining
- Current principal and interest: $1,368 per month
- Maximum cash-out loan at a 75 percent cap: $315,000
- New rate assumption: 7.75 percent on a 30-year fixed
- Closing costs assumption: 2 percent of the new loan, or $6,300
New principal and interest on $315,000 at 7.75 percent over 360 months is $2,257 per month.
Net cash received: $315,000 − $240,000 − $6,300 = $68,700.
Annual payment increase: $2,257 − $1,368 = $889 per month, and $889 × 12 = $10,668 per year.
Break-even yield: $10,668 ÷ $68,700 = 15.5 percent.
That is the whole decision. The $68,700 has to throw off a 15.5 percent pre-tax cash return to leave you where you started. If the next deal underwrites to a cash-on-cash return of 9 percent, this refinance costs you roughly $4,500 a year in exchange for feeling busy.
What counts as a good break-even yield
There is no universal threshold, and anyone who gives you one without asking about your old rate is guessing. The break-even yield is driven almost entirely by the gap between the rate you have and the rate you would take. A landlord sitting at 6.5 percent faces a far smaller hurdle than the one in the example sitting at 4.75 percent, on the same property with the same equity.
As a working range, a break-even yield under 8 percent is usually clearable with an ordinary deal. Between 8 and 12 percent you need a specific, underwritten use for the money. Above 15 percent, as in the example, the opportunity has to be genuinely unusual, and most of the time the honest answer is to hold.
Two refinements before you act on that range. The payment increase includes principal, and principal is not a loss, so a stricter read compares the interest-only cost of the new debt to the yield on the cash. And mortgage interest on a rental is deductible against rental income, which makes the after-tax cost lower than the pre-tax number suggests. Our guide to landlord tax deductions covers how that lands on your Schedule E.
If you are in the rarer position of being able to lower your rate, the test is simpler. Divide closing costs by the monthly savings to get the months to recover. Dropping that same $315,000 loan from 7.75 percent to 6.75 percent saves $214 a month, and $6,300 ÷ $214 is about 29 months. If you will not hold the property for 29 months, the refinance is a fee.
One hard constraint sits above all of this. Agency guidelines cap a cash-out refinance on an investment property at 75 percent loan-to-value for a one-unit property and 70 percent for two to four units, with rate and term refinances allowed to 85 percent and 75 percent respectively, per Freddie Mac’s maximum LTV requirements. Run the cap before you run anything else. It often decides the question for you.
6 mistakes that wreck the refinance decision
- Treating trapped equity as a problem to be solved. Equity sitting in a property is not idle, it is unlevered. It earns the property’s return at zero borrowing cost. Fix: compute the break-even yield before you call a single lender, so you know the price of the liquidity before you want it.
- Comparing the new payment to the old payment. The relevant comparison is not old versus new. It is refinancing versus the next best use of that equity, and holding is always one of the options on that list. Fix: write down the specific deal the cash goes into, with its own projected return, and put the two numbers side by side.
- Underwriting off a headline rate. Investment property, cash-out, unit count, credit score, and loan size all adjust your pricing upward from the rate you saw advertised. Fix: get a Loan Estimate from two investor lenders before you model anything, and use their numbers for both rate and closing costs.
- Ignoring the restarted amortization clock. Refinancing a loan five years in back to a fresh 30-year term resets the schedule and adds back interest you had already bought your way out of. Fix: price a 20 or 25 year term alongside the 30 and compare total interest over your actual hold period.
- Forgetting the lender will re-test coverage. Debt service coverage is net operating income divided by annual debt service, and the larger payment is the denominator. A property that cleared underwriting at the old payment may not clear it at the new one. Fix: compute coverage at the proposed payment and ask the lender for its minimum before you pay for an appraisal.
- Closing before the cash has a job. The higher payment starts the month the loan funds. Money sitting in checking for five months waiting for a deal has already eaten much of the first year’s return. Fix: close when the use is under contract, or build the idle months into the break-even yield so you see what the wait costs. That discipline is what separates a working BRRRR strategy from serial refinancing.
Your refinance or hold checklist
- Pull your current loan balance, rate, remaining term, and exact principal and interest payment from the most recent statement.
- Establish current value with a broker price opinion or three closed comparable sales, not an automated estimate.
- Apply the loan-to-value cap for your unit count and refinance type to get the maximum new loan amount.
- Request a Loan Estimate from two investor lenders so rate and closing costs are quoted rather than assumed.
- Compute net cash received and the annual increase in principal and interest.
- Divide to get your break-even yield and write it at the top of the page.
- Name the specific use of the cash, underwrite its own return, and compare it to the break-even yield.
- Re-test debt service coverage at the proposed payment before you order the appraisal.
Both ends of that checklist assume you already know what the property produces. If the operating numbers are not clean, start with our complete guide to rental property analysis, and keep the five KPIs every investor should track current so this decision takes an afternoon instead of a month.
When you want the math checked before you sign
The break-even yield is simple arithmetic. The hard part is being honest about the return on the money once you have it, because a refinance feels like progress whether the next deal clears the hurdle or not.
