You cannot purchase the property personally and then assign or transfer to your IRA.Any self-directed IRA vehicle will likely take 2-3 weeks to establish, largely due to the timeframe involved in moving funds from your current institution to the new institution. 

Do you have a list of those lending institutions that provide such services so i can do my due diligence?

As @Jay Hinrichs points out, if one includes total returns then one starts understanding why there is so much institutional money flowing around in more expensive markets. 

. - will refer to an account as self-directed if you choose your own financial product investments rather than working with a financial advisor.A truly self-directed IRA will be held by a specialty institution such as @Carl Fischer 's CamaPlan, Kingdom Trust, IRA Services Trust, etc. 

I am wondering specifically in the context of if you’re trying to qualify for a mortgage/loan/etc from a bank type of institution?  

Fannie instituted that former requirement due to "buy and bail" schemes during the Recession, where people with underwater houses would buy a similar home for way less than their current loan balance, and immediately stop making payments on the underwater home.

Are financial institutions starting to make use of the DOS clause more today than they used to or is this still a rare scenario? 

My biggest or most unusual problems were: abandoned vehicles, a person escaped from a mental institution, tenants with pet rattlesnakes that escaped their container, a round trip visit to the dentist for a wisdom tooth removal, a one way bus ticket from Kansas to Georgia, cashing $25,000 worth of checks each week for a group of guys from out of state, etc.  

You might even get lucky and sell to an institutional buyer.

Greenville has super low inventory and lots of institutional investor activity.
