Help with ARV!

[Andre Green]

I need a little assistance with doing some deal analysis on some properties that I am looking to wholesale. I know how to arrive at the price I should purchase the property for but I am having an issue calculating what the ARV is going to be so I can set an attractive selling price to get the property sold quickly.

Should I base the ARV soley on the price of other properties sold in the area within the last 6 months?

Should I be looking at square footage, etc?

Is Zillow a good measure for the value?

Any help and advice will be greatly appreciated!
