They probably do. My apartment was made in 1963, 63sqm (670sqft). "Zone price" (i.e. what the government considers the price of 1 sqm of development in a certain region) is 1100 euros, building age multiplier for that is 0.60 so we end with a 660 euro/sqm pric, for a total assessment of 41580 euros.

I'd be lucky if I got half of that If I actually tried to sell it at the moment.
