BRRRR — Buy, Rehab, Rent, Refinance, Repeat — is the most powerful strategy in residential real estate. Done well, it lets you recycle the same chunk of capital across multiple properties, building a portfolio without needing fresh down payment money for every deal.
Done poorly — usually with hard money and a too-tight timeline — it becomes one of the fastest ways to lose capital. The deciding factor isn't strategy. It's how patient your capital is.
Here's the math behind both versions, when each makes sense, and the three deal types where the BRRRR model fundamentally breaks.
The Five Steps, Quickly
- Buy — a property that needs work, at a price that reflects the work needed
- Rehab — bring it to rentable condition
- Rent — get a tenant in place at market rate
- Refinance — pull cash out at the new (higher) appraised value
- Repeat — use the recovered capital to do it again
The magic is in step 4. A traditional rental purchase ties up 25% down payment + closing + rehab — say $80K — and that capital is stuck until you sell. With BRRRR, the cash-out refinance returns most or all of that capital, freeing you to do the next deal without raising new money.
The "All-In Cost" Test
The fundamental BRRRR equation:
Where All-In = Purchase Price + Rehab + Closing + Holding Costs
And ARV = After Repair Value (the appraised value when complete and rented)
The 75% is because most cash-out refinances on investment property cap at 75% LTV.
If you can hit that ratio, you can theoretically recover 100% of your invested capital at refi. If the ratio comes out at 80-85%, you'll leave some capital in the deal (still fine). If it's 90%+, you're stuck with most of your capital trapped and the model breaks.
The Patient Version (Cheap Capital, Slow Timeline)
The version most successful BRRRR investors use looks like this:
- Purchase with a conventional investment property loan, 20-25% down. Rate around 7-8% in 2026.
- Rehab with cash savings or a HELOC on your primary residence. Take 4-6 months — don't rush.
- Rent when complete. Sign a 12-month lease at a quality rent (not the highest, the right one).
- Refinance 6-12 months after stabilization (seasoning periods vary by lender, often 6 months). Get the new loan at the appraised value, cash out up to 75% LTV.
- Repeat.
Why this works: your cost of capital is the conventional mortgage rate. The rehab money is your own cash (zero cost beyond opportunity cost) or HELOC (currently 8-10%). The holding period before refi is funded by rent and your own patience.
The Hard Money Version (Expensive Capital, Fast Timeline)
The version BiggerPockets podcasts love to glamorize:
- Buy with hard money at 70-75% LTV, 10-13% interest, 2-3 points up front.
- Rehab with the hard money draw schedule. Rush through it in 60-90 days because every month of holding costs money.
- Rent immediately, often before optimal stabilization.
- Refinance as fast as possible into conventional. Pay off the hard money.
- Repeat.
Hard money interest rates make holding cost real. On a $300K hard money loan at 12% for 6 months, you've paid $18K in interest plus $6K in points. That's $24K of pure cost — money that comes out of your spread.
The Math, Both Ways
Real example. $250K purchase. $50K rehab. ARV $400K. Closing/holding $10K. Rent $2,800/month.
Patient BRRRR (Conventional + Cash)
- 25% down on $250K = $62,500
- Closing + rehab + holding = $60,000 cash from savings/HELOC
- Cash invested: $122,500
- Refi at 75% of $400K ARV = $300,000 new loan
- Pays off original $187,500 loan
- Cash out: $112,500
- Cash left in deal: $122,500 - $112,500 = $10,000
- Total interest paid during hold (6 months at 7%): ~$6,500
- Effective cost of executing the BRRRR: ~$6,500
Hard Money BRRRR
- 25% down on purchase + rehab + closing = $40,000 of your money
- Hard money loan: $260,000 at 12% + 2 points = $5,200 in points up front + ~$15,600 over 6 months of interest
- Cash invested: ~$60,000 (your equity + points)
- Refi at 75% of $400K = $300,000 conventional loan
- Pays off hard money ($260K) + remaining costs
- Cash recovered: ~$30,000
- Cash left in deal: ~$30,000
- Hard money interest paid during hold: ~$15,600 + $5,200 points = $20,800
The hard money version frees up $30K of cash recovery vs $10K of leave-in for the patient version — at a cost of $14K+ in additional financing expense. You're essentially paying $14K to recycle $20K more capital faster. Sometimes worth it. Often not.
When Hard Money Actually Makes Sense
Three situations:
- You don't have the cash for the conventional version. If you literally can't put 25% down + rehab + holding, hard money may be your only path to the deal.
- The deal is so good it pays for the cost. If the spread between all-in and ARV is 30%+ instead of 25%, the hard money cost is still worth absorbing.
- You're stacking deals fast and need velocity. If you've got 3 deals you want to do this year and you can't fund them sequentially with the patient model, hard money lets you do them in parallel.
In almost every other case, patient capital wins on a per-deal basis. Where hard money proponents get the math wrong is they look at cash-on-cash return without subtracting the $14K-$25K of additional cost.
The Three Deal Types Where BRRRR Breaks
Type 1: Properties in markets where ARV is uncertain
BRRRR depends on a reliable appraisal at refi. In thin markets with few comparable sales, your $400K ARV expectation may come back at $350K — and suddenly you're trapped with 80% LTV and no way to fully recover capital. Avoid BRRRR in markets where comps are sparse.
Type 2: Cosmetic-only flips (no value-add headroom)
If the only thing you can do to the property is paint and new floors, you're chasing maybe 5-8% value lift. That's not enough to leave you under 75% LTV at refi. BRRRR needs forced appreciation — kitchens, baths, structural fixes, square footage adds, ADUs. Lipstick on a pig doesn't BRRRR.
Type 3: Markets where rents don't support refi DSCR
When you refinance into a 30-year conventional, the lender will run DSCR (debt service coverage ratio) — does the rent cover the new payment plus a margin? If your $400K refi produces a $3,200/month PITI and the property rents for $2,600, DSCR fails — and the refi gets denied. Always pre-check that rent covers refi debt service before you start.
How to Underwrite a BRRRR in 10 Minutes
Use the BRRRR calculator on this site. Plug in:
- Purchase price
- Rehab budget (be honest — add 10-20% contingency)
- Closing + holding costs
- ARV (validated by 3 recent comps within 0.5 mile)
- Refi LTV (start with 75%)
- Rent (validated by 3 active comparable rentals)
- Operating expenses (40% of rent rule for residential)
The calculator returns: All-in cost, refi proceeds, cash left in deal, post-refi monthly cash flow, and cash-on-cash on the residual capital. If cash-left-in is under $15K and post-refi cash flow is positive, the deal is real. If cash-left-in is $40K+, the deal is a hold (still fine, just not a true BRRRR).
The Bigger Point
BRRRR's reputation comes from a small subset of investors who execute it patiently in good markets with strong deal screening. The investors who blow up are almost always the ones who treated hard money as "free leverage" and rushed timelines.
For agents starting their portfolios, my strong default recommendation is: don't BRRRR with hard money on your first 2-3 deals. Use the patient version. Pay for your rehab in cash or a HELOC. Take 6-12 months between buy and refi. Build the rhythm. Then consider hard money once you've proven you can execute the cycle.
The agents who quietly build 10+ door portfolios over a decade are the ones who got rich slowly. The "I closed 8 BRRRRs this year" posters on social media are usually one bad market away from bankruptcy. Patient capital wins.
