In the one house that I still have some existing, it's only on an overhead light circuit with no insulation around it, and I minimize the load on the circuit by using only low voltage LED lights. 

Currently, I am self managing all the operations.

Property management is a "nickle" and "dime" business.  

In our experience, the #1 mistake landlords make when selecting a Property Management Company (PMC) is ASSUMING instead of CONFIRMING.

It's a big decision to self-manage.

I have contacts for long and short term managers in the Tampa/ St Pete/ Lakeland area. 

The asset management piece of investing is not focused on enough, in my opinion. 

Quote from @Marlena Hawkins: Does anyone know what insurance (liability, E&O etc.) is required for Property Management companies in DC and Maryland? 

Most property managers don't charge any markup.

If you are someone who has a bigger portfolio that you manage I would suggest appfolio or yardi.
