Not great, not terrible. This means a year and a half. If it saves you 300 000 eur on purchase of your home, it paid for itself.
I am a Czech; property prices around Prague are hopping mad, but top German cities like Munich are just beyond belief. Buying a house in an expensive region means debt slavery till the end of your days.
Waiting to 2022 does not sound as bad in comparison. You can probably have a big, even though unkempt villa somewhere in Sachsen-Anhalt for the price of a garage in Munich.
For this reason I don't plan on buying in Germany unless I hit the proverbial lottery.
But rent slavery is not much better, having my entire extended family living in this High CoL environment makes moving hard on the kids aswell... Atm I have a hard time being happy with any of the combinations of tradeoffs we could make.
