I was a long term tenant(15+ yrs) in a building managed by Ballard Realty Property Management. I have always found the staff to be friendly, professional, and responsive. Emergency situations were taken care of right away and things that could wait a bit (like replacing the dishwasher) were still handled in a timely manner. The building and grounds were well maintained and Ballard Realty always provided sufficient notice if there was a need to enter, such as the annual fire inspection.
I had a great experience as a tenant and would recommend them to any one looking for a rental in North Seattle. The only reason I moved was because of work place relocation.
If you are a property owner looking for a quality property management firm, it would be worth your time to at least make an appointment to see what the Ballard Realty staff could do for you.
