Cash-flow screen
Rent minus mortgage is not the deal.
Use this page to pressure-test the monthly cash left after real operating friction. The full app keeps the cash-flow result tied to the property, scenario, offer, and later actual performance.

This is a simplified educational screen. The app adds saved scenarios, offer history, PDF reports, address records, and portfolio context.

Worked example
Simple enough to check. Serious enough to challenge.
- Income: $1,950
- Vacancy and expenses: $640
- Debt service: $1,050
- Reserves: $125
Result: $1,950 - $640 - $1,050 - $125 = $135/month.
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.
