Monitoring this trend closely is advisable as it may impact investment returns.

By the way, I realize it is not entirely passive but I have several rental properties of my own and I will be able to monitor the investments properly.

I'm sure there are several of them around the US, but it is one of the ideal places for someone looking to move who wants to work 100% remote - relatively low home/rent prices, no state income tax, nice weather, good traffic/road infrastructure, access to the beach, plenty of arts and activities, etc.The risk is in the property you choose to invest in, not the market you choose.

Grandma didn't have a problem plugging in her old-timey radio, so your buyer totally won't have any issues plugging in their TV, computer, stereo system, vacuum cleaner, flat screen monitor, cell phone, refrigerator, dishwasher, modern HVAC, washer and dryer, upgraded lighting package, and stove... and then running them all at the same time over undersized, out of code wiring with no grounding.Totally okay.

You need to seek out the intangibles and see what issues have come up with the park (i.e. infrastructure, code violations, tenants' perception, etc). 

At the time the area was booming in interest because of a proposed transportation/infrastructure advancement.

Will continue to research but wanted to know your thoughts on this setup vs the empty lots and bring your own RV (I imagine you have to foster a community and culture and trust over years when there is no permanent infrastructure in place so it might negate the smaller start up cost). 

The infrastructure is great compared to 90% of countries.

Additionally the local property manager is likely to know more about the stability of the currency and infrastructure in that country, which can help when making your decision.Another option would be to go through one of the larger domestically based hotel chains to see if they have any condos for-sale in a particular country.

which market analysis and projection media/resources do you refer to most frequently when you are looking for a new market and monitoring your current ones?
