How do you figure out how quickly homes sell and rent in a market?

[Alec Jacobs]

Hello everyone.

I have been looking at some homes in my target market, (Beaver/Vanport area specifically), and I was wondering how I could figure out how fast homes rent out and sell in that area. Is there a way to find this data on Zillow or is there a specific website or none of the above?

This is mainly just for my comfort because it would be my first rental property and I would like to know how much of a cushion I would need left from a down payment to cover rent for a bit if needed. Also, if things go really south I would also like to know how long I would typically have to hold on to the home if it was a bad purchase. 

Thanks!
