Where are rental statistics pulled from?

Hey BP!

I wanted to dig deeper into the process for rental comps and I honestly couldn't find anything. Where are these comps coming from? I had a vacancy recently on my first home I've purchased as a primary (a few years back prior to having any knowledge of real estate or even that biggerpockets existed) . Property taxes doubled for me since then and I was forced to throw the property on the market for 200 more then what the average home of the same type was going for using rentometer, city-data etc. It got rented surprisingly and quick! I had a week and a half turn over.

Ultimately I began wondering where do people pull this information from? I listed the property, took the listing down after locking in a tenant but I've never reported what i'm receiving in rent, how long it's been on the market, etc. You can pull the information from using a few sites but are these sites tracking how often and what properties are going up and coming down? It was really just a general question and really me just trying to get to know certain areas more in depth.
