There's a property website which covers my local area, and every few weeks I'll do a search for the city-center, and sort by highest-price.

It's fun to look at the kinda house you could buy if you had €5 million in the bank. Even though I'd never have that much, and even if I did I wouldn't spend it on such a thing.

That's a habit I picked up when I lived in the UK and I played their national lottery once every month or so.

(/r/SpottedonRightmove/ is also a fun sub if you like this kinda thing; "right move" is a UK estate agents chain.)
