It's a good idea if your location is such that you don't worry too much about damage.

Does anyone happen to know if there is anyone that can help or at least guide me to a person, place or thing lol that would have reputable training.

Do I just use the realtor's complete list of contacts on their rolodex if they've proven to be a successful and have a good reputation on BP?

Another could be if you have a pinhole leak in the supply line...I'd be less inclined to assume supply just because it would probably be so wet that you'd have interior damage and a much higher water bill.

Out-of-state investors, do you recommend a reputable online source that provides crime rates and other demographic information of cities/zipcodes?

Has anyone had any experience with this company or can share insights into their reputation?

What if Tow Truck Tommy bangs up one of the other residents' cars while towing it out of the lot or towing it back to the lot, or damages the towed vehicle????

Secure the flooring since any leaks could cause subfloor damage under a toilet. 

However lack of communications from your GC / builder I agree frustrating and can be a killer to the GC's reputation..

Look for signs of water damage, like stains or discoloration on walls.Roof problems are also common.
