@Mason AdelmanDavid Lindhal- emerging markets I would also read Don Campbell (these are Canadian based but highly applicable conceptually) 97 Tips for Canadian Investors as well as Real Estate Investing in Canada 2.0Read some property management books also, Mike Butler has a good one, the BP Managing Rental Properties one is fairly good, Douglas Gray has a great one (extremely thorough but Canadian based, again, concepts applicable).

You must be extremely detailed oriented and organized and have the right team and sytems.

That combined with tactical empathy are extremely powerful skills to have.

Hedging would be a bad idea in my opinion given that the local currency is at an extremely low level against the USD (especially as a result of the Covid crisis), which by the way makes properties in these countries a bargain for USD investors.

We definitely don’t intend to lay with our feet up for the next 60 years, but we are no longer dependent on income outside of our investments which is really nice and extremely freeing.

@Eric DeNardo - Wholesaling in Denver is extremely tough.

@Aaron Zimmerman - I think I'd tend to agree with @John Warren, that this probably isn't extremely necessary unless a professional recommends it. 

There are a handful of tools on the market that do the same thing, but we've been extremely happy with Smartbnb.

It would be extremely difficult for me to make an investment decision based on something so precarious, which is why I would never recommend purchasing in these areas with the intent of short term rentals.
