Show the formulas
P&I = amortize(loan, rate, term)
NOI = (rent × (1 − vacancy) − expenses) × 12
cap rate = NOI ÷ price
cash-on-cash = annual cash flow ÷ (down payment + closing)
1% rule = monthly rent ≥ 1% of price
A screening tool, not investment advice. The 1% rule and cap-rate thresholds are rules of thumb, not a pass/fail verdict — verify every assumption before you buy.

Read the result honestly
A screening tool, not a verdict.
The 1% rule and cap-rate thresholds are rules of thumb — useful for a first pass, not a pass/fail judgment on a purchase. They don't account for appreciation, taxes, financing nuances, or your local market. Verify every assumption, and treat the output as one input among many.
After you buy
Own the guest relationship, not just the property.
The Direct-Booking Kit is how independent hosts stop renting their guest list from the platforms.
