Overpriced rent rates, price gouging.

It's not price gouging, it's supply and demand. It's hard to criticize people for taking advantage of the market. They are in the rental business to make money, not to provide discounted housing for gringos.

@Bart

I understand that, and you're entitled to your opinion.

The influx of and the ever increasing demand for local longer term rentals by extranjeros most likely is the main cause of increasing rent prices, as well as what the other user mentioned about a general price increases for most everything.

That said, the situations I encountered that I refer to in the subject line, were NOT cases of asking rental property owners to "provide discounted housing for gringos", as you noted in your reply.
