(I'm already seeing this in the towns I am currently invested)I know this hasn't really answered your question but I've been doing this for almost 5 years and it's working out well for me.

But having multiple banks working the deal I had one pull through for me.

So have to make sure you interview beyond just asking the simple "can you do this for me". 

For me as well as the seller.First, you have to define Sub to financing.Do you mean the reckless kind where you overpay for a property, take over the financing and borrow from others to cover closing costs and holding costs when you have no money, no credit, no income, no reserves and can't tell a warranty deed from a deed of trust and you close on the kitchen counteror do you meanbuying below market value, already having a nice income, having reserves, using escrow and title, already understanding the due on sale clause, have done a lot of creative purchases and know when to use and when not to use creative finance and how to recover if something goes amiss?

My track record makes buying SUbject viable for me.  

I'm in South Loop near the Loop, lake, Grant Park, CTA, and a variety of hospitals / schools, so renting out the room on a mid-term basis (32+ days) for a premium was the best strategy for me.

Any form of real estate, real estate syndications, or private lending is fine.

If you have 300k  equity its no brainer for me.

Tokenization of real estate assets can take numerous forms, but what you’re proposing is to separate the real estate “bundle of rights”, have the property owner sell one or more “rights” but not all of those rights, and represent the ownership of the rights that have been sold by tokenization utilizing block chain technology rather than the county “filing” systems currently in use.  

This has been a very helpful thread for me to consider Capital Syndicate.
