This tends to be more time intensive and more for someone that has a lot of time and limited income as you may find a "home run" type deal with some effort/energy.

I suggest your next lease have such a clause and that you make sure you can find the lease (but i have also somehow lost a lease recently).For where you are now, without a signed copy of lease i believe your options are limited.  

I just wanted to make sure there wasn’t a limiting factor of showings or interest.

The government of Costa Rica has a policy to limit development and doesn't invest much in infrastructure to bring tourism.

Quote from @Jonathan Greene: That's very limited information for someone to help you.

I moved to Reno Tahoe, NV where you can be 3 hours from the beach and there are low property taxes, no state income tax and limited new construction. 

Repairing to sell might recoup some costs, but given the market and your limited funds, selling “as-is” is likely the best option to minimize further losses.

You set the time limit for this clause, whether you want to be their source of funding for just the one project, for a year, for two years or forever. 

I would need to learn more about my options though as my experience is limited to podcasts and a few articles on that subject. 

The influx of tech jobs, manufacturing, mining, and Californians there is a strong population and combined with limited to no multifamily new construction we expect a severe housing shortage.
