Yes and No. I described gentrification. No, I did not participate in it because I received a Portuguese salary from the start. I'm working at university where the salary levels are fixed by state institutions. (Which is a huge problem if you want to attract senior researchers from abroad, and also a problem because it causes talented people to emigrate.) The reason why I paid a rent that was then higher than usual was because landlords in Portugal assume foreigners are wealthier and therefore it was very hard as a foreigner to get an apartment at the low pricing that my Portuguese colleagues were paying.
