Real Estate Investors — Quick FAQ

How do I analyze a rental property deal?

Check three numbers before you buy: cap rate, cash-on-cash return, and monthly cash flow. The free real estate ROI calculator gives you all three from price, rent, and expenses.

What's a good cash-on-cash return for an investment property?

Many cash-flow investors target 8%+ cash-on-cash, though appreciation-focused buyers accept less. The point is to see the real number honestly before you buy — run it in the ROI calculator.

What DSCR do lenders want on an investment loan?

Most DSCR lenders want at least 1.25 — the property's income 25% above its debt payment. Check any deal with the DSCR calculator.
