I'm wondering if anyone has advice on different elements of such a venture (did read good article from Mike Lacava from 2014), but wondering how best to size the build for my area, best type of lending to go after, other things to watch for in such a venture. 

We always have a notice of assignment as part of the closing package that satisfies the regs whether or not there has been an addendum in the contract. 

If you are accredited then you'll be able to receive marketing packages from sponsors and view them online through website like Realtyshares.

Zillow will not really work for selling, for packages you might try talking to net worth realty or own America and see what options they have.

This is way out of my element, as I am typically a value add investor. 

Then when you bring in other elements, like Anonymity--that can be like a moat or a dense line of trees keeping the invaders away from your assets.

Create a package for it and blast it around to investors on BP.See if someone is interested in buying it off you and you can do a FSBO

Rumor has it that they are doing packaging for amzn.

Check the new construction by KB Homes (Element) 2000 Sq.

If I had to do it all over again I would package together similar properties that I would likely want to sell all together.
