Been looking at a structure which will be optimal for having a portfolio of rental properties, financial investments, and all the other general life stuff, which will assist in asset protection, as well as tax liability etc.Thoughts on this?

You could buy a $225K home for example 3.5% down is $7,875.00 but there is closing costs which I mentioned seller credit or use the rest of your $6K.You could also use a DPA down payment assistance which covers 100% of the mortgage and in some cases depending on the DPA closing costs as well.   

What documents do they require, what credit scores do they allow, how do they verify previous rental history, etc.?

Quote from @Gregory Martin: I don't know what's allowed in your market.

I understand that you wont be getting a "deal" with turnkey, but I think what I was concerned with was that the listed price was well above what Zillow/Trulia suggested that property specifically was worth, and the range of prices for that neighborhood. 

@Samuel Coronado10.35% for land is still really good as well.

Between me and Kevin S  I haven’t heard back from him if his side of the thread wa deleted as well  

Karen, I've talked to hundreds of investors about their experiences on both of those platforms, as well as many others.

There are only a handful of lenders that allow it and they may need to see the full trust or just the certificate of trust.

@Jacob RossTwo answers for you- more times than not - equal partnerships don’t work out nearly as well as going it alone.
