BRRRR taxes: what buy, rehab, rent, refinance, repeat means

By Tom, CPA · Updated October 27, 2026

Part of: Rental Property Taxes

TL;DR: In a BRRRR deal, most rehab spending before the property is rented is capitalized into basis and depreciated, not deducted. Depreciation starts when the unit is ready and available to rent. Cash from the refinance isn't income because it's a loan, but the interest deduction follows how you spend the money, not which property secures the loan.

BRRRR stands for buy, rehab, rent, refinance, repeat. You buy a tired property, fix it up, rent it, then refinance at the new value to pull your cash back out for the next deal. It's a financing strategy, but every step has a tax consequence. Lavish Larry's version is to deduct the rehab, call the refi cash income, and hope. Frugal Fran's version is below.

CPA Warning Label: Rehab before rental is generally capitalized, and refi proceeds spent personally create nondeductible interest. Debt doesn't reduce gain on sale, so plan for recapture.

Rehab costs: capitalized not deducted

Under the tangible property regulations, amounts paid to improve property must be capitalized. An improvement is a betterment, a restoration or an adaptation to a new use. Work done to get a distressed property ready to rent usually counts:

• Betterment. Fixing a defect that existed when you bought it, or a material addition or upgrade.
• Restoration. Returning a property in disrepair to working condition, or replacing a major component such as the roof, HVAC or plumbing system.
• Repairs made during an improvement. Even a routine fix, such as painting, is generally capitalized if it's part of a larger improvement project.

And because the property isn't yet in service, there's nothing to deduct a repair against. Pre-rental expenses are capitalized into basis, or treated as start-up costs in some cases.

Some relief exists after the property is in service. The de minimis safe harbor covers items up to $2,500 per item or invoice with an annual election. The routine maintenance safe harbor applies to recurring work. The small-taxpayer safe harbor applies to buildings with an unadjusted basis of $1 million or less, if annual repairs and improvements are no more than the lesser of $10,000 or 2% of basis (as of Oct 2026, per the IRS tangible property regulations FAQ). These rarely cover a full rehab. See repairs vs. improvements.

Placed in service timing

Depreciation starts when the property is placed in service: ready and available for rent. It doesn't have to be rented. Under the mid-month convention for 27.5-year residential property (Pub. 946), a unit placed in service any time in a month gets half a month for that month.

• A unit listed for rent on October 15 starts depreciating in October.
• A unit still under construction isn't in service, even if you've signed a lease.
• Keep proof: a dated listing, photos of the finished unit, a certificate of occupancy if your city issues one.

Holding costs during the rehab, such as interest, property tax, insurance and utilities, are generally capitalized for a property that isn't yet in service. Under section 263A, interest and taxes during production of real property are capitalized, though small taxpayers may be exempt from parts of 263A. Ask your preparer which rule applies to you. Either way, those costs aren't lost. They become basis and are recovered through depreciation, or reduce gain on sale.

Cost segregation can split the rehabbed property into 5-, 15- and 27.5-year pieces. With 100% bonus depreciation for property acquired after January 19, 2025 (IR-2026-06, as of Oct 2026), new appliances, flooring and site work may be written off in the first year. See cost segregation.

Cash-out refi is not income

Borrowing money isn't taxable. You have an obligation to repay it, so there's no accession to wealth. That's true even if the new loan is larger than your basis, and even if you take out every dollar you put in. A cash-out refinance doesn't change your property's basis either.

The catch comes later. Debt doesn't reduce your gain on sale. If you refinance to $300,000 on a property with a $150,000 adjusted basis and later sell for $320,000, your gain is $170,000. You'll have only about $20,000 of cash after paying off the loan, before selling costs, but you'll still owe tax on $170,000. This is the BRRRR investor's version of a balloon payment. A 1031 exchange can defer it, and so can holding until death for the basis step-up. See cash-out refinance taxes.

Interest tracing on refi proceeds

The interest on your refinance loan is deductible according to where the money goes, under Treas. Reg. 1.163-8T. The property securing the loan doesn't matter.

• Part repaying the old loan or rehab financing on the same rental keeps that character. The interest is a rental expense on Schedule E.
• Part used to buy the next rental, the "repeat," is also rental interest, reported on the new property's Schedule E.
• Part used for personal spending, such as a car or vacation, is personal interest and nondeductible, even though a rental secures the loan.
• Part left in savings is investment interest while it sits there, until it's spent.

Trace by keeping refi proceeds in a dedicated account. Under the regulations, money spent within 30 days of being deposited can be treated as spent from the loan proceeds. Mixing it into your household checking account makes tracing harder. Loan points and closing costs on the refi are amortized over the loan's life.

Example

Illustration (made-up numbers): Frugal Fran buys a distressed house for $120,000 ($20,000 land). She spends $60,000 on a new roof, kitchen, flooring and HVAC, plus $5,000 of holding costs she must capitalize. It's listed for rent on October 1.

Fran pays off a $90,000 hard-money loan and puts $90,000 toward the next property's purchase. All $180,000 of interest is rental interest. Lavish Larry does the same deal but spends $40,000 of his refi on a boat. About 22% of his interest ($40,000 ÷ $180,000) is personal and nondeductible, no matter what the lender's paperwork says.

Fran's first-year return shows only $1,250 of depreciation, because the house was in service for just 2.5 months. Her rehab holding costs aren't deductions that year. They're part of the $165,000 basis. That's a timing difference, not a lost deduction. The full $6,000 a year starts in year two.

If Fran sells this house about five years later for $250,000, with about $30,000 of depreciation claimed by then, her adjusted basis is about $135,000 for the building plus $20,000 of land, or $155,000. Her gain is about $95,000 before selling costs, including the $30,000 of depreciation taxed at up to 25%. The refinance doesn't change that gain at all, even though she has much less cash in the deal.

Common BRRRR tax mistakes

• Expensing the whole rehab. A $60,000 "repair" deduction on a property that wasn't yet rentable is one of the easiest adjustments for an examiner to make, with penalties and interest.
• Starting depreciation on the purchase date. Depreciation starts when the unit is ready for rent, not at closing.
• Forgetting the land. The land portion of the purchase price never depreciates, and the rehab doesn't change that.
• Treating the refi as a basis reset. The new appraisal doesn't change basis. Only cost does.
• Losing track of loan proceeds. Without a tracing record, part of your interest may end up treated as personal.
• Ignoring state rules. Some states don't follow federal bonus depreciation, so your state return may show a different depreciation figure.

Repeat: keeping the cycle clean

• Use a separate bank account per property, or at least per deal.
• Keep the closing statement for each purchase and refinance.
• Track capitalized costs by property so basis is right on every Schedule E and Form 4562.
• Watch the passive loss limits. Large first-year depreciation may be suspended unless you qualify for the $25,000 allowance or real estate professional status. See real estate professional status.
• Consider whether frequent buying, rehabbing and selling makes you a dealer. BRRRR investors who hold for rent usually aren't, but those who sell after rehab may be. See fix-and-flip taxes.
