I think the less risky is a long term, but there are plenty of travel nurses that come through who would gladly do a short term (furnished, so something to consider) and won't wreck your place.

A bankruptcy that's not their fault, medical bills, foreclosure all could be reasonable.

I would not recommend doing this with travel nurses as they are already background checked.

When AirBnB first got hot in 2014 I used to sublease my rented 1/1 bungalow in Venice Beach when I traveled.

For example, travel nurses and digital nomads are typically looking for very different property types than a family relocating to an area.

Traveling nurses?

Unless you have large medical bills it's not going to make sense.

I've traveled a lot and the beaches in this area are top shelf. 

I bought in FL for appreciation and to break even at minimum as I didn't want to realize any add'l income in those properties annually but wanted appreciation and tax benefits. (2 bedroom units / close to the beach not not high-end luxury properties) Ohio for me right now = STR rents at 1.5-3x LTR rents, budget travelers & work travelers that are much more demanding.

We've backfilled plenty of pizza huts, boston markets, etc that have single tenant free standing buildings and generally these buildings are highly desirable for other uses as well, we are often shopping for a medical user for instance.2) There is usually another restaurant operator looking to backfill a space and not have the buildout cost associated with a shell space.like with all things in real estate its a spectrum, and what you are looking for in a return, flexibility, and budget will generally narrow what is feasible for you and your search.have you given any thought to the above (ie returns, budgets, other uses)?
