BRRRR Calculator
A complete suite of purpose-built BRRRR calculators on one screen — Purchase, SOW, Short-Term Financing, Holding, Refinance with lender-grade P&I, OpEx, NOI, Cap Rate, Monthly Cash Flow, and DSCR (Rent ÷ P&I). Every input is its own calculator. Every output is calculated live from your inputs. Walk into the refi closing table with a clear view of what you wire on day one, what you pull out at refi, and what the property is projected to cash-flow the day after. Maximum confidence about a deal's viability in minimum time.
How it works
Fill in every input the deal requires — address, comps, purchase, rehab, financing, holding period, refinance terms, OpEx, market rent.
REDA's calculators run the math — itemized Purchase + Closing, line-by-line SOW with split labor and material, Short-Term Financing with LTC and points, Holding across construction, Refinance against ARV × LTV with lender-grade P&I, OpEx, Leasing & Stabilization, and Contingency.
The BRRRR Returns Model recalculates live as you type — cash-to-close, interest carry, refi loan amount, new P&I, net cash returned, NOI, cap rate, monthly cash flow, and DSCR. Every dollar traced, every change instant.
What's inside
- Purchase & Closing Cost Calculator — title, escrow, recording, transfer tax, attorney, wholesale fee — every closing line itemized so you know exactly what you're paying at closing
- Scope of Work — 8 standard rehab sections, every line split into labor and material, every screw accounted for
- Short-Term Financing — LTC %, points, broker fees, hard-money rate, monthly interest across the construction period, plus exact day-one cash-to-close
- Holding Costs — property tax, insurance, utilities, lawn, HOA — normalized to monthly across your exact construction period
- Contingency — set as % of rehab or fixed dollar, with live actuals override once the project starts
- Refinance & Cash-Out — loan = ARV × LTV, lender-grade P&I via standard amortization, refi closing itemized, acquisition loan auto-paid off, net cash returned at refi
- Leasing & Stabilization — leasing fee (% or fixed) + marketing costs to get a tenant in place — the line that kills cash-on-cash
- OpEx — property tax, insurance, vacancy, maintenance, capex, prop mgmt — broken out line-by-line, normalized to monthly
- NOI & Cap Rate — NOI = (Rent − OpEx) × 12; cap rate = NOI ÷ total cash invested
- Monthly Cash Flow — Rent − OpEx − P&I — the dollar-on-dollar you bank every month after stabilization
- DSCR (Lender-Grade) — (Rent − OpEx) ÷ P&I — the way lenders actually underwrite — with live placement against the lender band (Lendable ≥ 1.25 / Borderline / Below)
- Live recalc across every calculator — change one line, every downstream number updates instantly. No Excel refresh, no broken cells.
