The undergraduates have been good but they are generally not very clean/neat people.

I really don't have any information or advice I can share with you, and it would frankly be really unprofessional of me to speculate on any past issues involving another party.  

I would Google really thorny condo questions and see what law firms were involved in cases that went to IL supremes, that would be a fairly good indication the attorney's had some experience.

Clean work.Are those porcelain tiles or?

You mentioned you purchased directly through a seller so I am guessing no agent was involved?

The reason why American business (this includes real estate businesses) have returned, on average, higher returns is because of the risk involved.

These tenants tend to be very good: clean, reliable, and professional.

It will be a project that involves some $$ investments.

My opinion is that it is all up to you and how involved you want to be.

Now that you have achieved the goal of paying down debt you can leverage your good credit to obtain either personal lines of credit or if you have equity in your personal home you may leverage that as down payment money on a acquisition loan or use that to purchase low costing investment property, depending on what market(s) you are looking to invest in.I've personally was in your same position and used personal loans to outright buy investment properties in various markets and I wish I would have known about lines of credit prior to getting involved with loans.
