Where to get solid ARV numbers?

[Dave Kennedy]

How do you go about getting an accurate ARV number?

Various free sites I go on show expected ARV's..etc but who knows how close they are. I looked at one for the house I live in and I don't think its remotely close.

Is there a way to calc it yourself? Do you get that number from an appraisor or inspector? Is that something you find when you put it under contract? Are there good pay sites out there?

Thanks for the help!
