Up to 10 properties: NOI, cap rate and cash-on-cash computed correctly, with the mortgage calculated and capex kept out of NOI.

Occupancy, payout per night and net income per month for Airbnb, Vrbo and direct stays, with stays that cross months split correctly.

2026-09-26The 1% rule vs real cash flow: one $250,000 rental at three mortgage rates
A $250,000 rental that meets the 1% rule ($2,500/month rent) makes $4,373 a year at 5.5% and $1,219 at 7.5%, and loses money if expenses run to half the rent. Why the 1% rule is only a screen.
2026-09-26How to calculate Airbnb occupancy rate (and the month-split mistake that skews it)
Occupancy = nights booked ÷ nights available, but stays that cross a month boundary have to be split by the night, or your monthly occupancy, nightly rate and income land in the wrong month. Worked example with two listings.
2026-09-26Cap rate vs cash-on-cash return: a worked example with a real duplex
Cap rate ignores the mortgage; cash-on-cash doesn't. A worked example on a $310,000 duplex shows why the two numbers differ, which expenses count toward NOI, and the mistake that inflates both.
