So in the negatives about retiring in Ecuadorthread I stated that the ultimate negative was change. These kinds of changes are not limited to Ecuador they are true for many other countries and a simple example is Brexit if negotiations don't go well many people's lives will be turned upside down.
So what are some changes that expats should anticipate to help them better deal with situations.
Currency exchange is one you should be wary of and it is not in your best interest to plan and make a budget based on favorable exchange rates because exchange rates IMO are both favorable and unfavorable at some point and usually for periods at a time. I personally had to endure this at one point in my life when the US dollar (salary based on) took a hit against many currencies. Everything increased including my children's school fees which alone were substantial but we overcame that because my wife got a job.
Health insurance, as was pointed out in the negative thread. We all know that many people found it enticing when comprehensive health insurance was only $70 a month. And many planned their budgets based on that.
Changes in the law whether it's immigration or employment, usually people with proper qualifications and updated paperwork are able to deal with these situations. But many are also helpless look at Brexit, DACA, and other situations unfolding around the world to get an idea of the anxiety that people are experiencing.
Changes due to natural disasters if you are living in area but found out for example it's flood prone or whatever because of lack of insight.
So what's the solution to these changes that expats at some point must face? One of the obvious ones is to have a flexible budget and that is something that is completely in your hands. You can achieve this by having additional means to pay for increases or you can downgrade your lifestyle and there is no shame in that especially if you love the place.
I'm sure there are more examples of changes and solutions that can be discussed.
