If, as a landlord, you intend to increase the rent on your property, then there are things that you need to do first. If it’s a period tenancy that’s on a rolling basis – say weekly or monthly – then usually you can only increase the rent once per year. If it’s a fixed-term tenancy then you can only increase the rent at the end of the fixed term or if your tenancy agreement allows this inside the fixed term. Again, this is something worth outsourcing to an agency if you can, as they have templates ready to go that cover you for most eventualities in a tenancy agreement, including in the unfortunate event that you need to evict somebody.
