It depends on why you want to buy, if you are looking from an investment point of view, analyzing the bubble does make sense.
we have bought an apartment too, if everything goes as planned we would be moving in few months time,
It made sense to us as:
we were looking for a minimum of 4 rooms apartment around Zurich. Not older than 5 years to have wasching machine and modern amenities with in. On the ground floor to have a garden. Not so far from the public transport, don't want to rely on my driving skills every time
But the rent is crazy at the moment a minimum of 3.5 k and there is always a queue of tenants applying.
The same house would be around 1.8k to 2k chf including some sinking fund kept aside.
