I am betting that there aren't that many STRs that offer a setup like that in your area. 

I will win…of that I am supremely confident.

Win that person over with logic and patience, and DIRECTLY address his/her/(it's?)

well if Harris wins she is going to open up federal lands for housing..

You might not be able to get the full amount you were wanting back in the cash out, but I am willing to bet you could get something if you own it outright. 

I bet it’s less than 1/2 the cost of solar to go this route.

Transparency always wins.3)Make sure to have mattress and pillow protectors, top-notch cleaners that take pictures of every sheet as they lay it before guests get there, and consistent pest control.

The tenants know the mini split is their best bet for controlling temp on their side, but they do not want to not pay for the energy to run it and would prefer the gas gets used (gas is included in their lease.) 

Of course, this is just my opinion but I bet I'm not alone..If I'm an investor, I think the returns you're able to achieve in Costa Rica are higher than normal because you focus on these large properties and, as @Martin D. mentioned, prices in that country are too high and returns too low.

Yes, I think that will be the best bet.
