This one tells you when to walk away. A mid-term rental screener built to catch bad deals — not to talk you into good ones.
Breakeven rent sits above market. This deal only works about $60k below asking.
It should land within a minute. If you don't see it, check your spam folder and drag it to your inbox so future teardowns reach you.
Open it, then go File → Make a copy to run your own deals.
Free. Google Sheets + Excel. No spam — just new deal teardowns.
The problem
Nobody buys a property expecting it to lose money. They buy it because a spreadsheet said 8% — a spreadsheet that assumed twelve months of occupancy, forgot the furniture, and never asked what happens in a normal bad year.
By then the money is committed, the furniture is bought, and the only exit is a sale at a discount. The screener costs you sixty seconds. Being wrong costs considerably more.
The tool
Purchase price, rent, occupancy, operating costs. It returns GO / CAUTION / WALK AWAY, stress-tests the deal against a realistic bad year, and names the exact assumption that breaks it.
Price, rent, occupancy, operating costs. Blue cells only.
GO, CAUTION or WALK AWAY — with the reason underneath.
See the rent and occupancy cushions before you make an offer.
Fit
You're weighing a furnished 30+ day rental, you underwrite before you tour, and you'd rather kill a deal early than discover the problem after closing.
You want a tool that confirms the deal you already love. This one is built to find the number that breaks it, and it usually does.
Why it exists
Most free rental calculators are lead magnets for someone who profits when you buy. They default to optimistic occupancy, skip the furnishing cost entirely, and never model a bad year — because a red verdict doesn't sell anything.
I underwrite all cash. No financing, no leverage math. One question: does the property earn its keep? This screener is the first thing I run, and it's conservative on purpose. Its job is to catch bad deals, not to talk you into good ones.
Free, and it takes about a minute to run your first deal.
