Rental property Calculator - Free!! No ads

Member since 2026 · 4 posts · 0 votes

for anyone else struggling with deal calculators. I’ve been slowly building a free calculator partly because I wanted the calculations to be easier and transparent. If you’re willing to try it, I’d love to know whether the way I’m presenting returns makes more sense.

One thing I sought to fix was the manual data entry as I browse deals on the MLS, I created an extension that when clicked it will take the data from the mls and allow it to pre fill a deal in the calculator. Let me know if this tool is helpful or hot garbage. 😆

    Hey David, great initiative building this! 👏

    One quick piece of feedback on the MLS auto-fill: pulling historical property taxes straight from the MLS is dangerous for out-of-state investors because it ignores post-sale tax reassessments. Auto-filling that old tax number creates a massive false positive for cash flow.

    We actually wrote a free guide on how to manually verify hidden expenses line-by-line so investors don't get trapped. It might give you some great ideas for safety features to add to your calculator!

    This is great feedback, I have updated the tax section with a big red warning to check and verify the tax estimate
