I increased mine by $20 a week, with another $10 a week in six months. If I were to increase it to the current market rate it would have been something like a $55 a week increase. I value the current tenant so I was ok with it. One problem that I keep having is the tenant always comes back with counter offers, so my rent keep getting further and further away from market rates. Next year I'm probably going to have to try to increase it more and see what happens.
