I wonder why Der Spiegel keeps lying every day, with rents "capped", how is this possible?
Germany's legal code, which regulates the private rented sector, rents are capped at a % of valuation of the property. I have provided you with links which explains it to you very simply, as a real estate developer you understand.
I always thought it was a credible newspaper, still I suppose you know what you are talking about.
I would expect more from you.
The airport mess is just going to take even more money out of the city that it doesn't have.
Just follow the list of best cities to live in and the you will see prices move on up.
