How To Get ARV (After Repair Value) With No Comps

[Marcus Hill]

What is the best way to find the ARV when you literally have no comparable properties close to the property that you are looking to make a deal out of? For example, I am looking at a house that is 1,800 sq. ft but every property close to that one is 1,400 sq ft or lower. Is this still a deal that I can put under contract, or should I stop evaluating this property and look elsewhere?
