Evaluating a homes value while looking for a deal

[Leonell Williams]

Good Morning BP family!

I have taken an interest in House hacking, preferably on Long island in New York. Probably a Noo0b question but I am curious about how to obtain an accurate estimation of a properties value. Using propstream, Zillow, and the counties Land Records website, I am getting 3 different estimations of the properties value. Trying to run numbers to see if a house hack is possible for FHA .I am not completely sure how to run numbers on a property to determine if its a deal or not so I plan on learning by evaluate a property value first. Any advice?
