What should we do: wife and I are potentially taking an international rotation to Europe.

I also make sure the potential tenant sends me references from their previous landlords and I end up calling them.

It definitely has potential, but I agree with what @Dan Heuschele said.

Would very much be interested in also seeing potential opportunities in Ohio!

So you will have to weigh the importance of maintaining legal status and potential savings you may get out of a LLC.

For that range you should not be having problems as you should be in B grade other than maintenance for capex that is missed but that is only a year or 2 and not vacancy.  .75% in Baltimore should be A grade with lesser vacancy and only potential initial maintenance. 

If you know where to buy, Philly is a good potential house hack market.

At the moment there are some potentially intriguing properties on the market here that may meet your criteria.

Do you think that will deter potential tenants?
