[paralelogram]

Try community housing. Since house prices are too expensive for a single person, try acquiring a building or a block as a collective (maybe 10-20 people). Gets you better conditions for loans, and if it's newly built, you can combine several amenities in one place, so you save a fair share of the burden you would otherwise have to get separately. (gardens, washing rooms, perhaps a garage and what not)

Easier said than done of course, and I'm not sure if Portuguese people are ready for it
