These are great ideas, and it's nice to know I'm not alone. 

I can tell you this:  If you do a nice job on the rehabbing, you will never be short on customers. 

Quote from @Jay Hinrichs: We live two blocks from McDonalds, my son worked at McDonalds, he had a car, the weather was nice, but he would still order from DoorDash.

They would make nice accent art pieces here and there.

Would it make a nice mid term rental if I need a revenue boost?

If I mainly want to vacation in Costa Rica and stay in a nice place, I rather make more money by investing elsewhere and rent a different villa every year, which is much more exciting from a lifestyle point of view, as I'll have variety.

I started with around $1,000, and my returns have been decent, usually around 8-12% a year, which feels nice compared to the ups and downs of the stock market.

I know a vacancy is tough and it can be hard to find tenants in the winter, but you have to weight the costs and benefits and decide.If it's harder to find renters in the winter, try offering a month-to-month lease just to get through the winter, then move back to a one-year lease in the spring.
