Hello,I hope you do not mind if I pipe in here.

An Umbrella policy provides additional coverage if the limit on your Homeowners or Auto policy is exhausted due to a covered claim. 

People bidding up way too high thinking that the inside of the house "might not be that bad" to find foundation issues, concrete in pipes, rot, termite damage and a previous fire all occurred there?

I would, personally, let him exhaust all his funds on the purchase and then you come up with a loan that finishes off the acquisition financing and then holds the rehab funds in escrow in an account you and your brother sign off on for withdraws.I do not think I'd put a lean on the property. 

Always get 2nd opinion on collapsed drain pipe.

Prolonged enthusiasm can be exhausting (failed offers, tours, travel) one way to remain engaged is to stay connected and in constant communication.

I like 3/2 brick or block houses (so I don’t have to paint) and are in the sunbelt (Specifically TX and FL markets with growing populations over 100k) because I don’t want pipes freezing, since we started investing while we were overseas.  

I occasionally look at contingent comps if I can't find anything comparable and have exhausted all possible avenues for sold comps.

If you want to DM me, I can send you some info on the suppliers.It's about $175/unit for the meter, but you need to include install cost (cut, tap the water pipe).  

But 1000 sq ft is exhausting.
