The cash itself is not income
Loan proceeds are not taxable, so a cash-out refinance lets you pull equity out of a rental tax-free. This is why refinancing is a common way to access appreciation without triggering capital gains the way a sale would.
Interest follows the money
The deductibility of the new interest depends on how you use the proceeds, under the interest tracing rules. Use the cash to buy or improve another rental and the interest is generally deductible against that activity. Use it for personal purposes and that portion of the interest may not be deductible.
Watch your basis and recapture
Refinancing does not increase your depreciable basis — you still depreciate based on your original cost. And because you have pulled cash out without paying tax, a future sale can produce tax that exceeds your remaining equity if the loan balance is high, sometimes called a phantom gain.
Interest tracing in practice
The interest on a cash-out refinance is deductible based on where the money goes, not on which property secured the loan (Treas. Reg. §1.163-8T). Say you refinance a rental and pull out $100,000: put $70,000 into buying another rental and $30,000 toward a personal car, and roughly 70% of the new loan's interest is deductible against rental activity while the 30% traced to the car is nondeductible personal interest. Keep the proceeds in a clean, separate account and spend from it deliberately so you can trace each dollar; commingling makes tracing — and defending it — far harder.
Deducting refinance points and closing costs
Points paid to refinance a rental are not fully deductible in year one the way points on a primary-residence purchase can be. Instead you amortize them over the life of the new loan — $3,000 of points on a 30-year refi is about $100/year. Other loan costs tied to the financing (appraisal, lender fees) are generally amortized similarly, while prepaid interest follows its own rules. If you later refinance again or pay the loan off early, any remaining unamortized points are generally deductible in full in that year.
The phantom gain trap
Because a cash-out refi is tax-free but doesn't raise your basis, aggressive refinancing can create a sale where the tax bill exceeds your remaining equity. Imagine a property with a $150,000 basis (after depreciation) that you've refinanced up to a $280,000 loan and later sell for $300,000. Your gain is roughly $150,000 — taxed via capital gain plus depreciation recapture — but after paying off the $280,000 loan and closing costs you may have little cash left to cover the tax. This 'phantom gain' is the hidden risk of stripping equity out of a property over time.
Cash-out refi vs. selling vs. a 1031 exchange
Each unlocks equity differently. A sale gives you full liquidity but triggers capital gains tax and depreciation recapture now. A 1031 exchange defers that tax but forces you back into replacement real estate and generally bars you from pocketing cash — any cash boot is taxable. A cash-out refinance gives you tax-free cash today while keeping the property, its depreciation, and its future appreciation, at the cost of higher debt and payments. Many investors refinance to keep compounding, but the right choice depends on your rate, cash needs, and long-term plan.
Effect on cash flow, cash-on-cash, and DSCR
Pulling equity out raises your loan balance and monthly payment, which lowers cash flow and can turn a comfortable property tight. Recalculate your debt service coverage ratio (NOI ÷ annual debt service) after the refi — lenders and prudent investors want at least 1.20–1.25. Cash-on-cash return can look distorted too: you've recovered invested capital (shrinking the denominator) while cutting cash flow (shrinking the numerator). Model the post-refi numbers on their own rather than assuming the deal is as strong as it was before you levered up.
Recordkeeping and common mistakes
The frequent errors: commingling refi proceeds so interest can't be traced; assuming all the new interest is deductible regardless of use; deducting refinance points in full in year one instead of amortizing; and forgetting that basis — and therefore depreciation — doesn't change with the new loan. Keep the loan documents, a clear record of how each dollar of proceeds was spent, and an amortization schedule for the points. Good tracing documentation is what turns a deduction from a guess into a defensible position.
Cash-out refi in a BRRRR strategy
The BRRRR approach — Buy, Rehab, Rent, Refinance, Repeat — relies on the tax-free nature of a cash-out refinance. After forcing appreciation through renovation, you refinance to pull most of your invested capital back out without a taxable event, then redeploy it into the next property. Two tax points make this work: the pulled cash isn't income, and the interest on proceeds used to acquire or improve the next rental traces to that business and stays deductible. Keep the chain of proceeds documented across deals, because interest tracing follows each dollar to its ultimate use.
HELOC vs. cash-out refinance
A home equity line of credit (HELOC) against a rental follows the same interest tracing logic as a cash-out refi: deductibility depends on how you spend the draw, not on the collateral. The practical difference is flexibility — a HELOC lets you draw and repay as needed, which can make tracing cleaner if you draw only for a specific business purpose. A cash-out refi replaces the whole loan at once, so you must trace the entire lump sum. Either way, segregate the funds and document each use to protect the deduction.
Rate-and-term vs. cash-out for tracing
A rate-and-term refinance that simply replaces the existing rental loan (no new cash extracted) generally keeps the same deductible character as the old loan — the debt is still tied to the rental. A cash-out refinance splits into two pieces: interest on the portion that replaces the old rental debt stays deductible against the rental, while interest on the new cash extracted is deductible only to the extent that cash is traced to business or investment use. Knowing which type you're doing tells you how much tracing work is required.
Refinancing, estate planning, and the step-up
Debt doesn't change the step-up in basis your heirs receive. If you hold a heavily refinanced rental until death, your heirs take the property at its fair market value date-of-death basis, wiping out the built-in capital gain and depreciation recapture for income tax purposes — even though the mortgage remains their obligation. This 'buy, borrow, die' pattern is why some long-term investors refinance to access equity tax-free during life rather than selling. It defers income tax indefinitely, though estate tax and the loan balance are separate considerations.
Timing a cash-out around a 1031 exchange
Pulling cash out near a 1031 exchange requires care. Refinancing the relinquished property right before an exchange to extract tax-free cash can be challenged as receiving disguised boot if it's too close to the sale and lacks independent business purpose. Refinancing the replacement property after the exchange closes is generally cleaner, letting you access equity once the exchange is complete. Because the IRS looks at the overall transaction, coordinate the timing with a qualified intermediary and tax advisor rather than refinancing on the eve of an exchange.
Converting a primary residence, then cashing out
If you convert a former primary home to a rental and later do a cash-out refinance, the interest tracing rules still govern deductibility based on how you use the proceeds — the property's history doesn't matter, its current use and the money's destination do. Note that converting to a rental also starts (or resets) depreciation based on the lower of adjusted basis or fair market value at conversion, and later refinancing doesn't change that figure. Keep the conversion-date valuation and the refinance proceeds records together for a clean audit trail.
A quick framework: refinance or sell?
Weigh three questions. First, do you want to keep the asset? If it still cash-flows and you believe in the market, refinancing keeps your depreciation and appreciation compounding tax-free today. Second, can it service the new debt? Run the post-refi DSCR; if it drops below about 1.2, you're trading resilience for cash. Third, what's the tax cost of selling? If a sale would trigger large capital gains and recapture with no 1031 planned, a cash-out refi accesses equity without that bill. When the answers point to keep-it, cash-flow-covers-it, and selling-is-expensive, refinancing usually wins; otherwise a sale or 1031 may serve you better.
Frequently asked questions
Is cash-out refinance money taxable?
No. Loan proceeds are not income, so the cash is tax-free when you receive it.
Can I deduct the new interest?
It depends on how you use the proceeds under the interest tracing rules. Money reinvested in the rental business is generally deductible; personal use is not.
Does refinancing raise my depreciation?
No. Depreciation is based on your original cost basis, not the new loan amount.
Do I pay tax when I take cash out in a refinance?
No. Loan proceeds are not income, so the cash is tax-free when received. The tax consequences show up later — through the interest deduction (based on use) and a potentially larger gain at sale.
Are the points on a rental refinance deductible right away?
Generally no. Points to refinance a rental are amortized over the loan term rather than deducted in the first year. Any unamortized balance is usually deductible if you pay off or refinance the loan again.
Can I deduct all the interest on the new, larger loan?
Only the portion traced to business or investment use. Interest on proceeds used for personal purposes is nondeductible. Keep proceeds separate and document how they're spent so the split is clear.
Does a cash-out refinance reset my depreciation?
No. Depreciation is based on your original cost basis allocated to the building, regardless of how you finance the property. Refinancing changes your debt, not your basis or your depreciation schedule.
Does interest on a rental HELOC follow the same rules?
Yes. HELOC interest is traced by how you use the draw, just like a cash-out refi. Draw only for a documented business or investment purpose and keep the funds separate to keep the deduction clean.
Is a rate-and-term refinance treated differently from a cash-out?
Yes. A rate-and-term refi that just replaces the old rental loan generally keeps its deductible character. A cash-out refi requires you to trace the extracted cash to its use to determine how much of the new interest is deductible.
