Most other methods of investing require much more risk (putting up your own money or credit rating) and are unable to just walk away if the deal doesn't pan out so a greater percentage of people there are looking for win/win scenarios.

No discussion of I'm a people person or not; or what the best method for someone with my personality should do to start out.

I always found it easier to buy all materials this also keeps cost down.This all about numbers so I like everything to be spelled out the KISS method is my theory ( Keep It SImple Stupid)!

After a long time;  years,  I got a letter essentially telling me to mind my own business - the EPA had their own methods and didn't need me helping them.Incidentally;  I had the exact same experience after reporting illegal immigrants.

I agree with what you're saying in most cases, especially standard flips, etc.In this case there's some additional considerations because it's personal...I'm also trying to figure out visibly respectful ways to handle this, because I'm looking to use these methods for future probate deals, and I want to have tools in my belt that I can use to demonstrate respect for the relatives and their loss.
