I’ve have two proposals from two companies that do this type of build.

Just make a proposal to the other owner er that’s good for you and fair to them, and see if they’re interested in your proposal.  

@Brian Carmichael Your proposal violates IRS self-dealing and prohibited transaction rules.

@Luke Rusten have personally used a higher price to get sellers to accept my seller financing proposals many times in the past!

We've been doing it this way in the construction industry for decades.Best way for you to know what's it gonna cost for your projects is get estimates/proposals from licensed contractors.

Also be mindful of existing or proposed restrictions - I don't recall anything extreme proposed in Ludlow or Dover, but Wilmington is being very aggressive in all but eliminating STRs.

That is not what I'm proposing here.The certification isn't an endorsement of the investment.

or is there never any such thing as a sincere policy proposal?

Most who propose this arrangement do so believing they are adding a layer of protection or separation between the property or themselves and the operation but that's total nonsense as well.

In the H.R. 3936, Built in America Act, it was proposed to extend the 100% bonus depreciation until January 1, 2027.
