Many investors make the mistake of only looking at gross rent vs. mortgage payment when underwriting a rental property. But that approach leaves out critical numbers that can make or break your cash flow.

Some key metrics I always factor in:

✅ Cap rate – How profitable is this property compared to its value?
✅ Cash-on-cash ROI – What’s your actual return based on cash invested?
✅ Property management & maintenance costs – Are you accounting for these hidden expenses?
✅ Rehab & capital expenditures – Are you setting aside reserves for repairs?

I recently broke down how I analyze deals using a rental pro forma to ensure I’m seeing the full picture before making a move. If you're not factoring in these numbers, you could be missing key risks.

How do you approach your deal analysis? What are your must-have metrics before pulling the trigger on a rental property?
