Of course. If a landlord has had an especially difficult tenant, they will jack the rent up to incentivize that person to move. On the other hand.. of you are a great tenant, the landlord will want you to stay. They may even keep the rent stable for you. There are very few landlords who jack up the rent out of greed alone. If you have a personal relationship with your landlord, and it isn’t some corporate management company, you have every expectation of being able to stay for years if you are a good tenant.
