For their area, they analyzed a number of rehabs that a particular team had done, then estimated the cost of rehabs per square foot after they completed the projects. 

Certain things like number of bedrooms square footage and amount of bathrooms whether or not theres a garage or on street off street parking also helps as well.

Hi @Khanesia Washington, Congrats on your success so far, and may it continue!  

For some reason it is in a square cut out a foot and a half deeper than anywhere else.

Hello Biggerpockets, I just purchased my first single family home in Vancouver, WA.

I know they have locations in Manchester and Nashua, and might have others in Concord or near the seacoast.What you sell it for will depend on where you move it to some degree.All of this, of course, will take time, so if you get it under contract and make the sale contingent upon getting all this squared away, make sure it's clear in your contract who is paying the current park fee while you're doing it.I hope that helps!

In Washington state for example they are nowhere near accurate because they are not 100% fed via IDX.

Some do desktop underwriting, which is akin to the Zillow estimate, because no one comes to view the house and the value is from recent sales and Price for the square footage. 

BUT, now I know and I will check into the tort against the agent/broker and what is involved here in Washington.

Fine at the higher end, when it's comparable to other units, better make sure the rooms are square as the eye picks up the imperfections much quicker running an angle to an intersecting plane, especially in in an empty room. :)
