Newbie - Fair Market Rents

[Blake Ashland]

We are looking at purchasing a few SFR as rentals. Wanted to see what if any advice people have for determining fair market rent. We are checking out as many recently listed rentals as possible but the particular area we are targeting has very few homes available for rental. Do you find zillow accurate - any idea how they arrive at fair market rent via their algorithm. Is there a way to find historical listings online? Any other advice in speeding up our education process?
