Let's see now! I have been doing rentals for over 18 yrs. and own several rental properties. What I would advise you to say to your Landlord is as follows: "If you are happy with your tenant, if the rent is always paid on time, if the tenant takes good care of the property, consider the fact that good tenants are very hard to find in this economy, therefore if at all possible " DO NOT INCREASE THE RENT! Point out that If the tenant moves out, and the property stays empty for a few months, then the landlord woud be losing a lot of money, much more then can be recuperated by a rent increase on the next rental.
