Contracts for Deed for Mobile Home Parks

[Jacob Hanson]

I have a small mobile home park under contract in Minnesota.  It is my first mobile home park.  The seller uses Contracts for Deed to sell POHs that get abandoned.  The seller's strategy is basically to keep reselling the same homes on Contracts for Deed to get down payments and higher cash flow from the CD payments on top of the lot rent.  The seller does this by doing CDs for anyone that can put money down on the POHs.  So I have two questions.

1.  Is this (contract for deeds) legal in MN?  

2.  Ethics aside, this seems like a good way for higher cash flow, without owning/being responsible for the homes.  Am I missing something?

Thanks BP
