Currently the only degrees that are here is liberal arts, accounting, and business administration.

I went with Advanta IRA for the administration of my self directed "checkbook" Roth IRA.

Tenant shall pay a $50 administrative fee at the office for the processing of this request.

How far along in the administration process has the estate been in? 

My wife has worked as an administrative assistant for much of her adult life, and I’ve been working (for over 20 years) in ophthalmology (Retina specialty), as a technician and biomedical photographer.

Of course if a regular joe tried to hire a GC the going rate is 340-350 per SF not including administrative items.  

Ask the PR to see Letters of Administration or Letters Testamentary.If the PR cannot provide the document then the probate process (Administration) is still continuing then you'll know why one of the reasons the seller is stalling but keep in touch with the PR as you'll want to create a buyer/seller relationship..

Before I got into real estate, I completed a Master's in Public Administration - research for my capstone included affordable housing from a policy perspective.  

If you're eligible for a Solo 401k, you'll pick up quite a few benefits compared to the IRA LLC: Compared to an IRA, Solo 401k contributions limits are roughly ten times higher.There is no custodial requirement for the 401k.You don't need the additional expense and administration of an LLC to have checkbook control.There is a built in-Roth component whereas IRAs are either traditional or Roth, not both.A spouse can also participate in the same Solo 401k plan.The Solo 401k has additional tax benefits over an IRA when investing into real estate using leverage.The penalties for prohibited transactions are less severe, though it's best not to utilize this benefit :)

And make sure you don't look at a tax bill with exemptions you not going to get.You'll also have utilities (for that period of vacancy), and maybe other administrative (like the cost for CPA related to your rental and lawyer for LLC) and incidentals.You should include property management too - 10%.
