If the buyers feel like they should get more money, they can do one of three things:1) re-negotiate with you to amend your original contract2) walk away from the closing table and refuse to sign (basically bringing the deal to a halt)3) suck it up and sign.I can't imagine a closing attorney would hold money back for any reason, unless he had it in writing and signatures from both parties that money was to be held back... that seems beyond me. 

If your SDIRA held the note and you sold a partial would not the remaining payments be already owned by the SDIRA, no need to re-purchase? 

However, I have not had stable employment for the past two years, but have worked/held internships every summer and winter since starting college (September 2012).

Other investors who have held single family, multifamily etc. ( more intensive assets) are also looking for more hands off investments.

This portfolio consists of both my own properties held by my business as well as properties under our management owned by other entities and individuals.  

Many people when they graduate are held down and forced to rent because of an issue with receiving financing.

I held a broker license for about 30 years.  

Probate could present challenges.Is the property held in their name or in a trust or some other entity?

You can not use a property held in an SDIRA for personal use.  

There are ethical standards, etc. that agents are held to, but most of those (in Ohio, anyway) aren't a negative impact on our business as investors/wholesalers.In Ohio, we have a few companies that you can pay to get your licensing classes done.
