Real Estate Search Tool?

[Mohammad Foro]

Does anyone know of a tool that allows searching for real estate by entering formulas for "positive cashflow"?

My formula is not complex... something like this:

High school rating > 8
"(Estimated Rent x 12) - HOA - Prop Tax - Insurance @ 0.3% - Vacancy @ 5% of rent - Debt Service @ 8%" > 0

I want to be able to customize the metrics, and find properties I can purchase as an investment.

If anyone is an avid user of StockRover and their custom metrics, that is exactly what I am looking for - but for real estate. I am happy to pay for it.
