The BRRRR method explained: buy, rehab, rent, refinance, repeat

BRRRR — Buy, Rehab, Rent, Refinance, Repeat — is a strategy for recycling the same down payment into multiple rental properties. Done well, it builds a portfolio quickly. Done poorly, it traps cash in deals that don't refinance out.

1. Buy: target distressed, undervalued, or off-market

BRRRR depends on buying below market value. The standard rule of thumb is the 75% ARV rule: purchase price + rehab should be no more than 75% of the after-repair value (ARV). That gap is what the cash-out refinance pulls back out.

Typical sources: MLS distressed listings, wholesalers, auctions, probate, tired-landlord direct mail. Move-in-ready retail listings almost never BRRRR.

2. Rehab: force appreciation, not luxury

The rehab's only job is to lift appraised value and command market rent. Over-improving with high-end finishes destroys returns. Get three contractor bids, build a written scope of work, and hold a 10–15% contingency for surprises.

3. Rent: stabilize before the refi

Most lenders require a "seasoning" period (3–12 months) of rental history before a cash-out refi. Screen carefully — a bad tenant delays the refinance and burns the strategy.

4. Refinance: pull capital back out

A conventional or DSCR cash-out refi typically funds 70–75% of appraised value. If you bought + rehabbed at 75% ARV, you recover most or all of your cash. The new mortgage payment must still leave positive cash flow at market rent.

5. Repeat

The recycled capital becomes the down payment on the next deal. Most investors hit a wall at 4–10 properties — conventional loan limits, DSCR lender concentration limits, or operational capacity. Plan for that ceiling early.

The numbers that decide if a BRRRR works

• ARV — confirmed with 3+ comparable sales in the last 6 months, same zip, similar beds/baths/sqft.
• All-in cost — purchase + closing + rehab + holding (taxes, insurance, utilities, interest during rehab).
• Refi proceeds — 70–75% of ARV minus closing costs.
• Cash left in the deal — all-in minus refi proceeds. Target $0–$10k; a "perfect BRRRR" is $0.
• Post-refi cash flow — rent minus PITI, management, vacancy, maintenance, capex reserve. Must stay positive.

Where BRRRRs blow up

• ARV came in low. The appraisal kills the refi math. Always underwrite to a conservative ARV, not the best comp.
• Rehab overran. Pad your budget; small SFRs rarely come in under contractor bids.
• Rates moved against you. Higher refi rate → lower DSCR → smaller loan or no refi. Stress-test at +1.5%.
• The market softened during rehab. Some markets BRRRR predictably; some don't. Check 12-month price-to-rent direction.
• Cash flow is thin. A $50/mo cash flow is one HVAC away from negative.

Underwrite the deal before you offer

BRRRR profitability is decided at the purchase, not at the refi. PLINTH's marketplace shows verified cap rate and cash-on-cash on every listing so you can pre-screen which deals are even worth rehab math.
