Anybody ever started a mail drop store?

I have a building on the outskirts of San Antonio, but it is considered San Antonio as far as a physical address.
It’s about a 2400 square-foot property. It has two bathrooms, full kitchen, and open area and seven rooms that could be used as offices or I guess it could be a boarding house too lol. It’s off of a very busy road with lots of frontage and its own personal billboard on top of the building.
I’m having a hard time figuring out what to do with the property, whereas it is more on the outskirts of town. I even considered owner financing it to somebody more ambitious or at least has more time than me.

During pondering what to do with the property it crossed my mind, it could make a good mail drop store. Of course there could be some other local businesses that might would want to use or share a couple of the offices that would possibly increase revenue. 

Has anyone ever started a mail drop store? What was your upstart expenses and do you consider it a profitable endeavor or something that just waste time?
