Simplified preview. The full calculator adds taxes, insurance, vacancy, management, and CapEx.

The problem

Most new investors find out a property was a bad deal after they already own it.

The rent looks solid. The price looks fair. But without running real numbers, it's easy to miss what actually matters.

1

Hidden costs add up

Vacancy, maintenance, and management fees quietly eat into profit that looked fine on paper.

2

The mortgage surprise

Rough mental math on financing often lands far from the real monthly payment.

3

No way to compare deals

Without a cap rate or cash-on-cash return, there's no real way to tell which property is the better buy.

The solution

One spreadsheet. Every number you need.

Enter your property's numbers and see the full picture in under two minutes — no formulas to build, no guessing.
