The constant change of the currency valuation to the dollar is a serious consideration. 

I wanted to ask, is there any currency fluctuation risk that you have to manage?

Engaging a real estate agent with experience in international transactions can also provide valuable guidance.Lastly, consider currency fluctuations and their impact on expenses and income.

It happens in real estate, the stock market, Crypto Currency and beanie babies. 

I day traded currency futures in a past life and always kept an online journal to keep me accountable, share what I was doing with the community and have a little bit of fun.  

Wouldn't it be a cheap way to do business, as long as our currency is worth more than other currencies?

I have no other assets except for gold - my money is made through trading currencies so I have no business to put up for collateral. 

And a lot of the shows come from Canada, so there's the USD->CAD dollar value difference (i.e. currency not clarified), plus the Toronto area, where alot of the shows focus on, is still an extremely competitive seller's market.

What will happen, hypothetically, once inflation o currency has pushed the small lenders out and the big lenders decide to become landlords instead of empowering the american dream and demand payment on their holdings?

Speculators get a bad name in the media but they provide a very essential function in ANY financial market be it stocks, currencies, commodities or real estate.
