This really depends on your personal context - how much do you earn, do you have a stable work contract, are you planning to stay in Lisbon for the next 5-10 years? Because if the goal is pure investment, prices in Lisbon have been in a bubble for a few years now, but if it's to live there, timing matters less than having financial comfort to pay the mortgage without stress. I'd personally say it's better to wait a year or two if you think it'll really stress you out, but you're right that the longer you wait, inflation keeps going up too (and then rents explode). What's your actual time horizon here?
