As long as you understand the wholesaling process and are able to work effectively with sellers/buyers/title companies there aren't really any "rules or restrictions" specific to the state. 

The only difference is he will hold the title unlike a true seller finance where he completely turns over the title.

The mortgage would be extinguished with the sale of the tax deed and then the quiet title action2).

Merely funding (transferring or acquiring) in a title holding trust is not, per se, a taxable event or avoidance device and the IRS treats as if vested in name(s) of person or entity who are beneficiaries.Buy the book from attorney Mark Warda from Jack Shea or others and read up on the topic.

Also Anyone have experience with doing quiet title on a foreclosure to get a warrenty deed?

@Rich Hupper, here is a thread that discusses IRR - even though the thread title is a misnomer:- https://www.biggerpockets.com/forums/311/topics/25...I don't know that "loss to rent" is any specific extra cost that you haven't already allowed for (but @Will Barnard might respond).

@Ryland Taniguchi  I have done a lot of work with SDRIA custodians over the years and I have never heard of any of them prepping RE docs  ... it would be a normal escrow with your escrow officer prepping your DT and if they are able your Prom note.they then send to the custodian for approval. then they fund.Once the nice things about working with lenders that have a true check book IRA they simply cut a check to title and its much smoother than the custodian approach.

A relationship with a title company representative can be a huge resource also. 

The problem is, it usually takes at least a few days to run title and actually buy a property.

Yes there is an adjustment for duplex when pricing the loan, please contact me as I can look at your title profile to see how is shown.Ben BaderIntercap Lending949-271-7009
