Where does Rentometer sample rents from?
Looking at a Pro report in a city I manage a number of properties in, none of my other rentals ever show as comps. They are advertised regularly on Zillow (including Trulia / Hotpads), Zumper (including Padmapper, Facebook, WalkScore), and our company website.
Sometimes they are advertised on apartments.com, rentlinx.com (and their syndicated sites), or on craigslist.
The only time I’ve found one of the properties I manage on a rentometer pro report is a fraudulent craigslist scam listing!
