Free rental analysis tool
Screen a rental before the spreadsheet starts lying.
This public version gives you the core rental math fast. It is intentionally lighter than the app: no saved assumptions, no offer history, no PDF, and no portfolio tracking. The point is to see whether the deal deserves real underwriting.
Rental Property 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
- Monthly rent
- Down payment

Worked example
Simple enough to check. Serious enough to challenge.
- Price: $225,000
- Rent: $2,100
- Operating costs: $725/month
- Debt service: $1,230/month
Result: $2,100 - $725 - $1,230 = $145/month before reserves and surprises.
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.
