Rental Contract - renewal
I have a rental contract which runs for the duration of a year. It says that the contract will tacitly be renewed after that period. The automatic renewal can be prevented if either tenant or landlord give notice three weeks before the date of renewal.
Furthermore, the contract includes a paragraph stating that the annual renewal triggers an increase of the rent of around a fifth of the rent. I would like to avoid such a significant increase in the rent. Before reaching out to the landlord to find a mutual agreement, I was wondering where I stand legally. From what I have read so far, the annual renewal is not a thing in Belgian rental law. And what about the significant increase in rent? Is it even legal to include that in a rental contract?
Thanks a lot in advance for your advice!
