Show HN: Rentalytics – Find rental property deals that actually make money

Hi HN,

I’m a software engineer and real estate investor. I grew tired of scrolling through property listings and manually analyzing each one just to figure out which of them are actually profitable as rental properties. This was especially tiring as only a few properties ever end up being worth the trouble.

So I built Rentalytics — a system that automatically pulls active listings in a market, runs the numbers, and ranks them by:

- Cash flow

- Cash-on-Cash Return

- Debt Service Coverage Ratio (DSCR)

For the proof of concept, I started with Columbia, SC. Last week: out of 1152 active listings, only 85 were worth considering.

The idea is to expand city by city (Charlotte, Raleigh, Greenville are next), while improving the metrics and UX.

Right now:

Free = weekly “Top 5 Deals” email

Pro = weekly full ranked spreadsheet

Would love feedback from HN on:

- Other metrics worth automating?

- CSVs vs dashboards — which is more useful to you?

- How should I prioritize which cities to add next?

- Any cities you'd especially like to see as an investor?

Thanks!
