As @Bill F. mentioned, the best place to find the expert MH attorney who would be able to guide you on that would be at the Manufactured Housing Association in the subject state.  

I love the theory behind a subject to deal, however i'm curious how some of you guys handle the potential drawbacks of the deal.I'm not very worried about the due on sale clause, it seems that this happens so rarely that statistically it can almost be ignored. 

I have just one tenant who pays in cash now (used twenties from a cash job) and I get all the logistical difficulties, but really...it's CASH.In the brief interim of time between receiving my wad of greasy, stinking twenties in my hot little hand and the moment I stuff those bills into the slot of the ATM, I feel alive.

Yes, what you are describing is called purchasing a property subject to the existing mortgage, or Subject-to for short.

Furthermore, if the LLC is generating active income, more of the income would be subject to SE tax.

You can convince someone to sign their property over under a "Subject To" deal.

Or am I just better off buying property as a trust with a subject to and seller carryback?

And the way the report looks it can seem overwhelming with all the details broken up by subject/location then summaries... but when you start condensing it and putting value to it many times it is nowhere as bad as it seems.

That is very subjective .
