Costa Rica does make a good portion of their income from tourism so there is some effect going on.

For that reason alone I wouldn’t touch anything that is not in a big city (Madrid, Barcelona, Sevilla, Bilbao), where I expect people to still relocate looking for better jobs, or in a nice area of the coastline, where you can count on either good tourism or well-off retirees.However, I believe there are opportunities in some neighborhoods and niches.

We've experiment with answering services vs. live inbound telemarketing operators.

Is it in an area with vacationer appeal and steady tourism - you mentioned a beach was close by.  

You should consider speaking with them and reading their, "Inbound Marketing" book to get a good background on what works.

From what i understand prices are down, but I couldn't get a handle on whether tourism was down.

We do have some nice industries like trona, tourism, agriculture, etc, but make no mistake we are an energy driven state.

Maybe someone can develop an app that provides bio-feedback and will send inbound callers with elevated blood pressure and/or heart rate to voicemail? 

Plus inbound calls close better than outbound always.  

I'm reluctant to touch anything that is heavily leveraged to tourism at this point due to future lockdown, travel bans, etc.
