If so, how is that facilitated, are there service providers who handle it, and what are the approximate costs?

I planned to have my realtor facilitate for us. 

. :)  he had a company called California Wrap even.. and it was those transactions and many other Ca investors like my dad that then created the All inclusive Deed of trust.. to facilitate sub too in a much safer manner.. its a great document folks should google it.. its what we use to transfer title in CA on a wrap or sub too. 

You have to use a facilitator, so you can't do this on your own. 

@David Huynh Generally, expenses incurred to facilitate the purchase of real property are capitalized to the basis of that property. 

I commend you for taking on an investor, facilitator, role.

They facilitated everything a normal agent would do, they just didn't find the deal for me. 

I considered investigating acquiring credit cards or other lines of credit to facilitate this. 

Specifically, which lenders are still willing to work with Investors, which would prefer to work with "facilitators"?

What about the lenders and banks who authorized the lending practices that facilitated this?
