I don't want to talk too much about his story because I'll get emotional and stupid both about him and the painful history of my area, but again, he has been a critical part of our operation.Do you also have or have you lost important relationships with key specialists who are aging out of the work force?

They were mostly turn key. 

Properly screening tenants is key.

Usually, they offer cash for keys to the occupants.

If you're self-employed, the Solo 401k plan will likely work better for you.A few Solo 401k benefits: Compared to an IRA, Solo 401k contributions limits are roughly ten times higher.There is no custodial requirement for the 401k.The Solo 401k can allow you to borrow funds from the plan, unlike with IRAsYou 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 square footage is the key here though making sure I don't go over 1000 sf.

What key factors should I consider to determine if this is a good deal or not?

@Dmitriy Fomichenko in regards to 'converting' traditional funds over that are already in my SOLO401K to the ROTH component, if those 'funds' are say a rental that I paid 100K for, do I need to get an official appraisal of that property to covert things?

Should you do the move-in inspection when you had them the keys on the move-in day? 

Diligent follow up is also key.
