It is very difficult to prove in court that other people or animals are living there.

consult a lawyer and make sure you did everything legally. the animals never worry me but lawyers do... hahahaha... but seriously make sure u do talk to pros and do it all 100% right

Is there such an animal?

First, REOs and short sales are two entirely different animals.

A model very similar to what I do except I do shared housing a whole different animal.

It's really a different animal with it's own subset of buyers.  

., flood plain map a few resources on due diligence.Land is a whole different animal so if you can't wholesale be careful about closing on them.

Definitely no cash flow to be had from the first two options, and flipping is a totally different animal from what you are really looking for it sounds like (passive income), plus aside from the risk of flipping in general as someone with no flipping experience, you are also taking on risk with having partners set up like that.

I get this from one of our neighbors- a rental if it is run down and has loud trashy tenants and cars on blocks would diminish value and rightly cause neighbors anger-- all our rentals are in well established developments-- I give my card to both side neighbors and ask them to please call us if there is excess noise, traffic, residents,etc-- it creates much good will & I also tell the new renter that we have done this with the neighbors-- it puts renters on notice that you will find out about unmoved lawns, animals, etc. as long as your home looks like a home and not a shabby obvious rental, your neighbors will calm down.

I only do same day closings. 2 weeks or longer is a totally different animal.
