Investment Property Calculator

Estimate the monthly mortgage payment on a rental or investment property. Investment loans carry larger down payments, higher rates, and stricter debt-to-income (DTI) review than owner-occupied loans — model your payment before you run the numbers on rent.

Frequently asked questions

How is financing an investment property different?

Lenders usually require 15–25% down, charge higher rates, and evaluate your debt-to-income ratio more strictly on non-owner-occupied loans. Some may count a portion of projected rent toward qualifying income.

What down payment do investment properties need?

Most conventional investment-property loans require at least 15–20% down, and more for multi-unit buildings. Set the down payment field to match your program.

How does DTI differ for investment loans?

Because the property is not your residence, lenders scrutinize your debt-to-income ratio more closely and may add reserves requirements. Use the DTI calculator to check where you stand before applying.
