There are very few sellers of notes right now, so who are you buying and selling too.You are going to be sadly dissappointed and realize after 3-6 months you probably wasted your money.Your best bet is to join some groups on FB or elsewhere and start to learn that way.Let me ask you this question: Have you spoken to any note investor out there to ask them about the environment today to actually get into notes? 

I am considering them as my real estate agent and property management company, so any feedback regarding how they work, how trustworthy they are, and how it is to work with them is greatly appreciated; thanks

My bet is both those will be redeemed prior to auction.  

Even still, investors will often want equity in the projects.Giving equity to private investors can hedge your bet.

In Metro Detroit area, police will not remove these types of occupants (they are afraid of scamming landlord having police remove legal tenants), calling them a "civil matter" forcing landlord to start court eviction process. thats a good question Drew.. but I bet if the police are aloud just a little bit of fact checking and do police work they can determine the fraud very quickly.. 

If the real estate is producing a steady return, you can make more aggressive bets with stocks or other alt assets.

Getting multiple contractors involved will be your best bet to get a reliable estimate, though you need to come up with a scope of work.

Out of state may be your best bet, everyone on this thread has suggested great markets.

@Robert Lum  you bet you can troll around a site like BP read their books listen to the pod cast of those that are successful and talk about their business's.. its inspiring and motivational.but if you really want to learn the nuts and bolts you need to get in the game.the best and least expensive way to do that is to simply take a pre license course in your state.. learn the laws ( the real laws not the BS that is talk about on line).. terminology etc. then go to work with a brokerage in the aspect of Real estate that interest  you.. there you will get REAL training by those that are successful you get on a team.. you get paid as you learn.
