But it's not everywhere equally, as this rental cost index shows:

Rents in Aveiro are 30% less than in Porto, in Braga 1/3 lower. Lisbon is more than 40% more than Porto.

Porto is less Disney-fied by mass tourism than Rome, Paris, Florence, Venice, Washington, Miami Beach and London.

My basketball and tennis courts in Porto, Perafita and Matosinhos have not yet been Disneyfied.

Until the Portuguese government takes decisive action to increase the supply of affordable housing through a combination of market-engineering incentives and taxation of the wealth (local and expat) the real estate bubble has produced, real estate market failure will continue to hurt the average salaried Portuguese citizen. If I end up buying an apt in Porto after this bubble bursts as the ECB raises interest rates, I'd be happy to pay a 1-2% tax on its value to finance housing vouchers for locals so they don't give their votes to far right Chega/Ventura, the only big winner from real estate market failure. But most of Portugal's real estate investor class hasn't yet learned a simple principle: sawing off the tree branch upon which you sit never ends well.

I'm 68 and learned this simple idea more than half my life ago: the % of people who have an inherent right to grow old in the same world they grew up in is a very simple number: zero.
