If you think that real estate is “overheated” just look at the last 12 months of the stock market, crypto currencies, etc.

I have no clue how Guyana's currency fluctuates so I can't help there.

The theories I hear regarding this one is that over time the dollar (or whichever currency you use) is worth less and less.

So I made the mistake of asking how their book their trades assuming it's in dollars or other currency.

Have you ever heard of a currency bubble?  

Lots of currency, debt, Trump stuff thrown in there that I don't fully understand at this point. 

Now some foreigners in years past tried to double dip and time the currency exchange rate in their favor to a weak U.S. dollar.

US$ is considered a safe haven currency and tend to move up in economic/market turmoil which makes GOLD against US$, not a good bet. 

Because I know that houses are more expensive in general in canada even after accounting for the currency exchangeAnd in your experience (how ever much that is) have you ever seen a fourplex for $100,000 to $150,000 in canada anywhere?

Another big reason is that a lot of Asian markets are not as open as the US and still have currency control and ownership issues.
