This is what the State of CO has to say about these PREDATORS:Consumer Advisory: Long-term Home Ownership Concerns(Wholesaling/Assigning Transactions and Distressed Rescue Transactions).

I built up a very large portfolio doing foreclosure rescue sub too. 

Then I leveraged the $2k cash for down payment on the next deal, and on and on.HARD MONEY TO THE RESCUE When I first approached a hard money lender to finance my first real deal, he literally laughed me out of the door.

And I rescued the folks that I bought it from also.. they were working with a local wholesaler who had no ability to  close would just give them stories.. and that led them right to the brink of foreclosure I got to them the day before Had them file BK  then set up my buy to from the Trustee.. thereby giving them some CASH which they were going to totally lose if it went to Trustee's sale. 

If you do this deal the way you've described you will literally have NO exit strategy other than holding for long enough for appreciation/debt pay down to rescue you.

If the occasional litter box odor is strong, usually a quiet word to the tenant is all that is required.If they are non-responsive, it's a good bet there are other issues too, and the pets are the least of your problems.PS, although I am an animal lover, and do significant rescue and fundraising for animals, I don't allow the four breeds that my insurance company doesn't allow:German Shepherds, Rottweilers, Pit Bills and Dobermans.

I also help with animal rescue here.

Many states (and I don't know about MN) have added various 'foreclosure rescue' statutes because REI were conducting business that regulators believed was not in the interest of good public policy.

She then "rescued" 3 dogs.

ONe of the BP turnkey guys who specializes in lower end Memphis stuff came to his rescues. but that would have been a perfect example of why some want to place their own tenants.
