The reason people do their DAMNDEST in Germany in areas where prices are rising to keep an old contract alive
is that each time a NEW contract is made it is ENTIRELY a matter of market forces.
Actually, it's mostly because of "protection times" due to older contracts. The older a rental contract the higher the contract termination period. For example, traditionally, rental contracts of over 20 years of age usually award a termination period of up to 1 year (i.e. time from required notice until actual termination of contract).
Money comes into play when a raise of rental payments didn't happen for several years during the contract time. In that case, especially since the maximum raise is restricted to 30% per year, it might be hard for the landlord to raise to the maximum technically possible with a new treaty (about 20% above maximum Mietspiegel numbers for the area, with the same equipment).
Mietwucher is very common and, sadly, has been somewhat "legalized" by courts in the last few years. Especially with new contracts it's very hard to do anything against it, that's why the Mietspiegel should be among required reading when looking for a new rental apartment.
