Situation: couple renting apartment (had original lease, now Part IV) for 9 years. Never had rent increase.
Landlord requested meeting and is looking for a 4% increase on each year they've been there.
My understanding is that landlord can apply a 4% increase now on current rent only.
Have I misunderstood?
People involved are vulnerable but have no arrears and have been generally excellent tenants.
ETA: they are in a rent pressure zone.
