Rental rate increase

[Rick Zink]

I have never had a renter in one of my rentals long enough to raise the rate on them.  One of my houses I am charging well below market value I have recently learned.  The current renter is dependable...pays on time, takes care of the place, etc.

I would like to increase the rent but at the same time do not want to lose the renter as you never know who is coming next.  I do my due diligence prior but I am sure anyone with experience can tell you that you can only go so far and nothing is guaranteed.

Can someone maybe give me some pointers on approach/methods of raising the rent?
