BRRRR model
Model the refinance before you buy.
BRRRR deals break when purchase, rehab, rent, ARV, and refinance terms do not agree. This public tool gives the first pass; the app saves every version as the deal changes.
BRRRR Calculator
This is a simplified educational screen. The app adds saved scenarios, offer history, PDF reports, address records, and portfolio context.
Inputs
What this calculator asks for
- Purchase price
- Rehab
- ARV
- Refinance LTV
- Rent
- Post-refi loan terms
Outputs
What you get back
- Cash required
- Refinance proceeds
- Cash left in deal
- Post-refi cash flow
- DSCR
Worked example
Simple enough to check. Serious enough to challenge.
- Cash into deal: $68,000
- Net refinance proceeds: $49,000
Result: $68,000 - $49,000 = $19,000 left in the deal.
The public page is meant to create a directional answer. Before an actual offer, replace each estimate with address-level evidence: rent comps, parcel taxes, insurance quotes, lender terms, inspection findings, and local operating rules.
Why move into PropLurk?
Calculators are useful. Connected deal records are better.
A single output does not tell you what changed, why it changed, what offer it supports, or whether the deal improved after diligence.
