@Ari Hadar I don't know if it is the same on the app, but the @ sign and wait till all the possibilities pop up.

I googled “retirement plans for General contractors”, stocks and real estate popped up.

Assuming it's composition shingles; look for rippling, nail pops and any work done around vents or valleys that could lead to leaking in the future.

This is a mom and pop run building where the owner did the management and repairs himself over the course of ownership in the last 8 years.

Make a list of mom and pops and start mailing/calling them. 

Sure you hear of one or two pops here or there, but it is tough to do. 

Out popped the house.

Having my spreadsheet means I can quickly pop in a couple numbers and know if it's going to work or not and how much I can bid  if there are multiple offers quickly.

But if I'm wrong and someone pops up and decides to sue, then I could be in some deep legal trouble.

I'm curious also since I tell people to almost NEVER sign buyer rep agreements.  95% of the time the buyer broker hangs out and then pops up to claim a commission due without doing much work.
