actually not always.
In commercial leases the property tax and renter tax is seperatly stated and chaged and if the renter defaults it is converted to rent due and owing.
In residential leases the rent and property taxes are included as seperate clauses in leases where the landlord is astute enough to put it in.
this is important as property taxes may go up and the landlord needs to pass that cost through to the renter.
It is not a question of “covering the cost in the rent” it is a question of drafting the lease to ensure the taxes are paid by the renter.
Depends on the individuals.
You get a renter who
(1) has a quiet lifestyle
(2) has never been late with the rent by one day
(3) takes care of the property like it was his own -
you do not necessarily want that renter to walk when you tell him you are passing through a tax increase.
I'm that kind of tenant. I have rented a home three times in my life, each time for 4+ years. I have only been hit with a rent increase once, when a new owner bought the property and decided he needed to recover his total purchase price in the next five years. I moved out in three weeks.
Last I heard he had been through four tenants in the next 30 months. Always did want to ask him how that was working out.....
