If your roofer can tell that the pitched portion of the roof has 8 layers on it, I would think he should have been able to do the same for the flat portion using the same methods, unless this area had no exterior edges because of where it was positioned on the roof.

I am looking for any tips, methods, or other that may help me become skilled in the area of determining the ARV of a property. 

What is a "flip an hold" either someone has given a name to (an) old method(s) or you're getting things mixed up. 

This seems like a non-conventional method, but if they do the trick, I think it's an awesome idea.  

I don't think my current method of paying my handyman an $85 trip charge is cost effective. 

I work with residential, commercial, and government, I never charged anyone for estimates, some take me plus an architect 3 days to complete.For the investors reading this, please note different contractors have different rules, regulations, and methods on how to run their business.

But I'd be counting on refinancing asap to pay that off, cash out and continue with the BRRRR approach.

Hello BP, sometime ago i read "The definitive guide to using seller financing to buy real estate", and only thought that to prevent due on sale clause, that would mean i can only used this method on debt free property.

We should definately share our process and methods...investing in US remotely from Canada definately brings its own challenges but its deable. 

Granted it's just a rule of thumb but that's a $500/m spread in the two methods.
