On the open market, I like to use 1.25% rule to scan potential deals for investment, but found it hard to do this automatically. Zillow can show both price estimate and rent estimate, what I would like is to divide these two and filter it by 1% or 1.25%.
I am pretty sure Zillow doesn't have this feature. https://www.zillow.com/advice-thread/Advanced-Sear...
Does anyone know which website can do this ?
Hot Pads will give you a rent-ratio heat-map, which is going to similar to what you're talking about.
Zillow has API's you can code against to extract data that you're interested and processes it yourself, if you're inclined to do-it-yourself.
