The BRRRR method in real estate, explained

How each step works

Buy — the deal starts with an acquisition below market value, usually a distressed, dated, or neglected property where the seller is motivated and the property needs work. The discount at purchase is what makes the math work later. Many investors apply the 70% rule as a quick filter: offer no more than 70% of ARV minus the estimated rehab cost.

Rehab — renovations are targeted at what drives appraised value: kitchen and bath updates, mechanical systems (roof, HVAC, plumbing), and exterior condition. Cosmetic work that makes the property appealing to tenants isn’t automatically what moves the appraiser’s number. Know what the local market pays for. Granite countertops in a neighborhood where comparables have laminate won’t add dollar-for-dollar.

Rent — the property needs to be rented, ideally to a tenant who has made at least one payment, before most lenders will refinance it. Seasoning requirements vary by lender, but 6–12 months is common. The rent you achieve matters directly for the refinance, since the lender’s DSCR calculation will use it.

Refinance — the cash-out refinance is where the capital gets recycled. The lender orders an appraisal of the renovated property. If the appraised value hits or exceeds the ARV you underwrote, and the new loan at 70–75% LTV covers most of your all-in cost, you pull cash out. That proceeds check goes toward the next deal.

Repeat — that recycled cash becomes the down payment on deal two, with no fresh savings required.

A worked example

Item	Figure
Purchase price	$110,000
Rehab cost	$45,000
Carrying costs (insurance, utilities, 6 mo.)	$4,500
All-in cost	$159,500
ARV (appraised after rehab)	$220,000
Cash-out refinance at 75% LTV	$165,000
Capital recycled	$165,000
Cash left in the deal	none ($5,500 back)

On these numbers, the investor pulls out slightly more than the all-in cost. The remaining loan balance is $165,000 on a $220,000 asset, leaving $55,000 in equity, none of it the investor’s cash. That zero-cash-left result is the best case BRRRR is sold on, and it needs every number above to hold.

The monthly payment on a $165,000 loan at 7.5% over 30 years is about $1,154, before taxes and insurance. For the property to carry positive cash flow, rent net of operating expenses needs to exceed that payment plus the escrow. At $1,600/month gross rent with a 40% expense ratio, NOI is about $960/month ($11,520/year), which does not cover $1,154/month in debt service. Rent has to clear about $1,925/month just to break even on that payment, and roughly $2,400/month to reach the 1.25 DSCR a lender will underwrite to — or the loan balance has to come down. Cash-on-cash return and DSCR are what you check here.

Three risks that sink BRRRR deals

Appraisal gap. The appraiser’s number is not yours to set. If the ARV you underwrote was $220,000 and the appraisal comes in at $195,000, the refinance at 75% LTV gives you $146,250 instead of $165,000, and your all-in cost was $159,500. You are $13,250 short. Underwrite to a conservative ARV, and know the all-in number you need the refinance to clear.

Rate sensitivity. The refinance rate determines whether the property generates cash flow after debt service. A deal underwritten at 6% may break even at 7.5% and bleed cash at 8.5%. Run the cash flow at a rate a point or more above current rates before you commit.

Rehab overruns. Renovation budgets on older properties slip. A plumbing rough-in opens a wall that reveals knob-and-tube wiring; a structural issue appears after demo. Build a 10–15% contingency into the rehab budget and treat it as money already spent.
