I rent in Germany, and it's not as absolute as Mummyoflittledragon says. There are minimum periods before which a landlord is not allowed to require you to redecorate if you move out. It's five years for most rooms, 7 for some. And of course there is a concept of wear and tear. Nobody expects (for instance) flooring to be replaced before at least 10 years.
Precisely because people can treat rented places as their homes (which they are), tenants don't want their landlord's furniture. They want their own. If you move out and decide to leave (e.g.) your kitchen in, it's often the case that an agreement is made with the next tenant who pays you a proportion of the value.
There's none of this ridiculousness with time-limited contracts. Almost all contracts are time-unlimited, with a minimum notice period of three months on both sides. After five years, that period begins to increase for the landlord, but never for the tenant. A landlord has to have one of a specified and small number of reasons to end the contract (your unreasonable behaviour, needing the property him- or herself - which is only possible for private landlords and is interpreted quite narrowly - or rent arrears). You can't even be thrown out if the landlord wants to sell. You might agree to leave, but you will usually have all your costs paid and perhaps compensation on top. The buyer would have to give you notice on the basis of wanting to live there themselves, and pass said stringent test.
It's brilliant. I would be very reluctant to buy here, especially outside the big cities. I'd be too worried about never being able to sell. I know people in extremely prestigious jobs who actively choose to rent.
OP, I have encountered plenty of the attitude you speak of among Brits. Assumptions about us because we rent (in wilful ignorance of the differences in culture).
