I was down there recently and spoke to this realtor. The deal was paid for 100% in Bitcoin and then immediately converted to cash. Really no different than any other currency conversion I would presume. The seller wasn't asking for Bitcoin, the buyer wanted to use Bitcoin.
I didn't ask the purchase price of the sale, but for that neighborhood, I would say you are in the $100k-300k range for just the lot.
You can build an amazing house for $100/sqft (granite, high end features, etc) and a very nice house for $60/sqft.
Have a full time live in maid for around $150/month. Very attractive place to retire! Or just move, if you have a portable job/income stream. Beautiful country, very safe, etc.. According to the UN rating system it rates right next to the US for safety. Surprising for the 2nd poorest country in the western hemisphere...
