Underwrite a Buy-Rehab-Rent-Refinance-Repeat deal — cash recovered, money left in, and your cash-on-cash return.
BRRRR works when you can pull most of your capital back out on the refi. This calculator runs the full math: all-in cost, ARV-based refi proceeds, money trapped, monthly cash flow, and the 70% rule check.
Direct answers to the most common questions, in plain language. Skim if you're in a hurry; dig deeper below.
Buy, Rehab, Rent, Refinance, Repeat — recycling capital through cash-out refis.
BRRRR is a real estate investment strategy: buy a distressed property, rehab it to force appreciation, rent it for cash flow, then cash-out refinance to pull most of your capital back out — letting you "repeat" with the recovered money.
Ideally $0–$10k — the goal is to recover all capital on refinance.
A "perfect" BRRRR returns 100% of your invested capital on the refinance, leaving you with a cash-flowing property and no money tied up. Realistic deals often leave $5,000–$20,000 in — still excellent ROI given the cash flow + appreciation that remain.
Most lenders cash-out refi at 75% of After Repair Value.
Conventional cash-out refinances on investment properties typically max at 75% LTV of the after-repair value (ARV). To return all your capital, your purchase + rehab + closing costs must total less than 75% of ARV.
Aim for purchase + rehab + costs ≤ 70–75% of ARV.
The classic "70% rule": never pay more than 70% of ARV minus rehab. A property worth $200k after rehab needs purchase + rehab + closing ≤ $140k for the refinance math to work clean.
The mechanics in short answers — no jargon, no upsell.
A property needing meaningful work, purchased at a discount. Cash or hard-money loan upfront — banks won't conventional-finance a property in distress.
Targeted improvements that maximize appraised value: kitchen, bathrooms, flooring, paint. Track rehab spend strictly — overruns kill the math.
Stabilize the property with a paying tenant. Banks usually want 30–90 days of seasoning before they'll refi.
New conventional 30-year mortgage based on appraised ARV. Most lenders cap cash-out at 75% LTV on investment properties.
Use the cash pulled out to buy the next BRRRR. The "Repeat" is what makes the strategy a portfolio engine instead of a one-off flip.
Designed so anyone can model their situation in under a minute, with or without a finance background.
How much capital you get back when you cash-out refi at 75% LTV.
Original cash − refinance proceeds = capital trapped. Aim for $0.
Annual cash flow ÷ remaining capital — the ROI number that matters.
New mortgage payment, taxes, insurance, vacancy, capex — actual net.

Everything you might ask before, during, or after using this tool.
Flipping: buy, rehab, sell — capture the spread as profit. BRRRR: buy, rehab, rent, refi — keep the property and pull most of your capital back out. Flipping pays one-time, BRRRR pays cash flow + appreciation forever.
Typically 6–12 months end to end. Purchase + rehab: 1–4 months. Stabilize with tenant: 1–2 months. Bank seasoning: 3–6 months (most lenders require 6 months of ownership before cash-out refi). Then refinance closes.
Yes, on conforming loans (mostly Fannie/Freddie). Limits vary: 75% for 1-unit investment property, 70% for 2-4 unit. DSCR loans (commercial-style) and portfolio lenders may go higher in exchange for higher rates.
Most conforming cash-out refis require 6 months of title seasoning (you've owned the property for 6 months). Some "delayed financing" exceptions allow earlier cash-out if you bought all-cash. Always confirm with the specific lender before assuming.
Then you can't pull as much cash out, leaving more capital trapped. This is the #1 BRRRR risk. Mitigation: be conservative on ARV (use the lowest comp, not the highest), and walk away from deals where the math only works with optimistic ARV.
Cash is simpler — no carrying costs during rehab, faster close, no refi seasoning complications. Hard money lets you do more deals with less capital but adds 8–12% interest costs and tighter timelines. Most BRRRR pros use both depending on the deal.
BRRRR works best with cosmetic and minor mechanical rehabs — kitchen, bathroom, paint, flooring. Major systems (roof, HVAC, electrical, foundation) eat rehab budgets and timelines and rarely add proportional ARV. Avoid foundation issues, full re-roofs, and unpermitted additions.
A "perfect" BRRRR with $0 left in has infinite cash-on-cash return. Realistically, 15–25% cash-on-cash on remaining capital is a strong outcome. If cash-on-cash drops below 8%, the deal is mediocre — better deals exist.

Distressed properties trade at a discount to fixed-up properties because most buyers want move-in ready. That discount is the BRRRR opportunity.
By forcing the property to ARV through rehab and then refinancing at appraised value, you're effectively selling the property to yourself at the higher number — turning sweat equity into real cash you can recycle.
The repeatability is the magic. A house-flipper makes money once per deal. A BRRRR investor builds a portfolio of cash-flowing properties using mostly the same capital over and over.
All-in cost = purchase price + rehab + closing + holding costs during rehab.
Refinance proceeds = ARV × 75% − refi closing costs − any outstanding loan being paid off.
Money left in deal = all-in cost − refinance proceeds.
Cash flow = rent − new mortgage P&I − taxes − insurance − vacancy − management − capex reserves.
Cash-on-cash return = annual cash flow ÷ money left in deal.
ARV comes in lower than expected.
Cause: optimistic comp selection during analysis. The bank's appraiser uses the most conservative comps, not the most aspirational.
Effect: cash-out is capped at 75% of a lower number, leaving meaningful capital trapped.
Mitigation: always run two ARV scenarios — your expected number and a 10% lower stress test. If the deal only works at expected, walk away.
