I would look into the syndication world as that will 1, probably be the best legal structure and 2, will teach you how to raise the money. 

I am in the process of purchasing a new rental property and expanding on this initiative in next few years.

Of course, and we were already in the process of doing it.But we wanted to go faster and build it TODAY, not kick tires and experiment for a year.

Some pros with turnkey: you don’t have to source deals, no rehabbing, streamlined process, fully rehabbed property(with the good companies), some can come with tenants in place cash flowing from purchase. 

Can a private mortgage be structured to qualify as a standard mortgage, enabling the borrower to refinance it in the future?

I'm in the process of buying a single-family house to renovate and flip in the next few years but I'm always looking for deals and/or other investors to connect with.

I own small amount of RE already so I’m familiar with process. 

Would love to know if there's a part of this process I am missing should another chance like this come up again..Thanks! 

But a CRT simply to lower your tax bill will still end up with the bulk of the benefit going to the charity not you.These trusts are basically large properties in all different sectors that are owned in a trust structure originating in ...wait for it...Delaware. 

Once i’m done renovating, I could refinance and pull the profit out and use that to pay the debt off and repeat the process.
