How to Raise the Rent on a good tenant

[Calum Bressington]

Hello,

I recently bought a property in Cleveland and inherited the tenant.  The tenant is amazing and has been there for a long time, she says she has no plans on leaving.  The property is rented at 850 a month with market rent average at 1300 and she covers all utilities and yardwork.  I don't want to be greedy but also that is a humongous gap. Should I just raise it a little per year to get it closer? How much is fair?

Thanks so much for your input.
