One quick addition from their official website that shows why they may be more accurate than other "estimate sites"."

I have all of these sites up when searching for 1-Local Realty MLS (local vs national also has cheaper deals) 2-Crime Reports (at my price point, i want ot make sure you're only choosing "safe" neighborhoods and most municipalities have some sort of online presence with 30-60 days of crime reports) 3-Rentometer (this is a pretty accurate rent aggregator to tell you the low/medium/high rents for that address 4- Craigslist to see what type of rental activity is listed there.4) While you're there, meet up with some turnkey managers and property managers.

If you're not confident generating accurate numbers for all these items yourself, move on.

Simply by asking the same client as above if that yearly money includes any salary, would make the information in the application more accurate.
