Guide

How to use the calculator

01

Define the deal structure

Enter purchase price, down payment, interest rate, and loan term. These four inputs determine your financing picture — monthly mortgage, required cash, and leverage level.

02

Layer in real income and costs

Set monthly rent and annual expenses (taxes, insurance, HOA). Use real numbers from the listing, tax records, and insurance quotes — not estimates.

03

Stress-test your assumptions

Adjust vacancy rate, property management, and maintenance reserves. Conservative investors use 8–10% vacancy, 8–10% management, and 5% maintenance.

04

Read the results like an investor

Focus on monthly cash flow first, then cash-on-cash return. A deal that cash flows negative from day one rarely improves. Target $100–200/month per unit minimum.
