It seems a bit daunting to think how I am going to retain all of this information.

It creates a better lending leverage for you and they retain some control of the investment on paper.

Then there is $9800 in retained value left. 

just a few I have seen in the forums include: due on sale clause, financing (especially later refinancing and programs not available), representing yourself (say in landlord tenant), continuing need for insurance for duty to defend  (ie to cover legal fees to defend against a case), 50 state survey , piercing veil, merits versus land trust, or benefits over just landlord policy plus umbrella, transaction fees, ongoing responsibilities and formalities to retain protections, etc..probably a few more specific questions too as the bigger pockets audience is varied and pretty sophisticated ....but these are some usual suspects (also search site on terms like LLC or due on sale, asset protection, etc for more...) best of luck and look forward to your piece...

Anyway my end buyer wanted me to write in a clause that said contract was contingent upon financing so that she had an exit, so I also wrote in that if buyer fails to perform my only remedy is to retain the earnest money deposit so that if she did back out due to financing I could.

However, unlike banks just selling REOs or bulk REO packages (if that actually happens), the RTC retained an equity interest in the properties.

As for preferred stocks, I am cautious there as well as I wouldn't be surprised to see Uncle Sam exercise his muscle and step in to tell banks that they CANNOT pay common OR preferred dividends.

I love 60's muscle cars and would rather have a muscle car than a Lambo.

I think it will profit those with enough financial muscle to withstand the gestation period of the investment.....I really will not want to wake up in 2018-2020 with regrets...why didn't I but when it was 2015!!!!

A more realistic goal is to be able to sell for enough profit so that the duplex remaining in your ownership will rent for a positive cash flow and you will have been able to get all your money out of the deal with a 75% loan to value mortgage remaining on the unit retained.
