Market for above-garage rental?

[Brittany Scantland-Lall]

Hi BP Team - If this is not the best forum for this - just redirect me :)

We have a SFH with a detached garage. The garage is a 2 car garage with a large shop space in front of the cars (basically a separate room). Above the garage, there is a fully finished room w/ a window AC unit. It runs the full length/width of garage (so 2 cars wide, 2 cars long). The prior owner had a pool table up there. We've used it as a workout space/art studio, but have never really put it regular, good use.

Having basically dived in and swam in several of the BP podcasts recently, I'm into the idea of maybe rehabbing that space for rental as either an office space or art studio space - either a co-working space, or just for one individual.

Does anyone have experience doing something like this? Is there a market for it? If not, and in the alternative, should we consider something like a mid-term rental for travel nurses? 

Either way, we will need to get it plumbed and reconfigure the entry (since it is through the garage).  We would consider new windows and possibly a mini-split to replace the window unit.  Much of the actual space could be cosmetically handled.

Any insight or experience with this kind of property would be welcome!  Thank you so much for your time!
