Can you elaborate on this more? Does a tenant have the right to force an owner to extend a lease, perhaps? From my experience, an owner does have more rights to the property and its use, purely because they are the owner. If a lease ends, they can increase the lease payment[1], and if the current tenant cannot afford it, they have to move. Is this not how it works in your country?
[1] Many (most?) places here do have a limit on how fast you can increase rent prices to help alleviate the problem of kicking someone out by pricing the unit out of their reach all of the sudden.
