BRRRR Method Calculator Guide

12 min readUpdated April 2026

BRRRR without calculator = guessing at equity, refinance surprises, cash flow disappointment. BRRRR with calculator = accurate projections, known cash-in-deal, predictable infinite returns. Here's how to calculate BRRRR deals correctly.

What is BRRRR?

Buy: Purchase below market value
Rehab: Renovate to increase value
Rent: Place tenant, generate cash flow
Refinance: Pull out invested capital
Repeat: Recycle money into next deal

Calculate BRRRR Returns

BRRRR Calculator Components

1. Purchase & Acquisition

  • Purchase Price: What you pay for property
  • Closing Costs: 2-3% of purchase
  • Initial Down Payment: 20-25% typically
  • Total Initial Investment: Down + closing

Example: $150k purchase, $37.5k down (25%), $4.5k closing = $42k initial

2. Rehab Costs

  • Renovation Budget: Itemized rehab costs
  • Contingency: 15-20% buffer for surprises
  • Holding During Rehab: Mortgage, taxes, insurance during work
  • Total Rehab Investment: Renovation + holding costs

Example: $30k rehab + $6k holding (3mo) = $36k total

3. After Repair Value (ARV)

  • Comparable Sales: Find 3-5 recent comps
  • Conservative Estimate: Use average, not highest
  • Appraisal Reality: Banks often appraise 5-10% below expectations
  • Used For Refinance: Determines how much you can pull out

Example: Comps at $215k-225k → Use $220k ARV conservatively

4. Refinance Analysis

  • Refinance LTV: 75-80% typical (use 75% to be safe)
  • Cash Out Amount: ARV × LTV - payoff original loan
  • New Loan Terms: Interest rate, payment on new loan
  • Refinance Costs: 2-3% of new loan amount

Example: $220k ARV × 75% = $165k refi - $112.5k payoff = $52.5k cash out

5. Cash Flow & Returns

  • Monthly Rent: Based on comparable rentals
  • Operating Expenses: Taxes, insurance, PM, maintenance
  • New Mortgage Payment: Based on refinanced amount
  • Monthly Cash Flow: Rent - expenses - new mortgage

Example: $1,800 rent - $650 OpEx - $950 mortgage = $200/mo cash flow

Key BRRRR Metrics to Calculate

Cash Left in Deal

Total invested - cash recovered via refinance

Goal: $0 (infinite return) or minimal amount

Forced Equity

ARV - total all-in costs

Goal: $50k-100k+ equity created

Cash-on-Cash Return

Annual cash flow ÷ cash left in deal

Goal: Infinite if $0 left, or 20%+ if cash remaining

Refinance Recovery %

Cash recovered ÷ total invested × 100

Goal: 80-100% recovery rate

BRRRR Calculator Mistakes

❌ Overestimating ARV

Bank appraisers are conservative. If you think $230k ARV, bank might say $210k. Use conservative estimates or you'll get stuck with cash in the deal.

❌ Forgetting Refinance Costs

Refinance closing costs are 2-3% of loan amount. On $165k refi = $3.3k-5k. Reduces cash-out by this amount.

❌ Using 80% LTV Assumption

Many lenders only do 75% on cash-out refinance. Using 80% = overestimating cash-out by thousands. Use 75% to be safe.

❌ Ignoring Cash Flow After Refi

Higher loan = higher payment. Make sure cash flow is still positive (or at least break-even) after refinancing.

BRRRR Success Criteria

Minimum Requirements for Good BRRRR

✓ Recover at least 80% of invested capital via refinance

✓ Create $50k+ in forced equity (ARV - total costs)

✓ Break-even or positive cash flow after refinance

✓ Purchase at least 25% below ARV

✓ Conservative ARV estimate (use lowest reasonable comp)

✓ Clear refinance path (good credit, verifiable income)
