I have a friend who is considering buying a waterfront property with some dockage in the Annapolis area. He was asking me if I had any idea what the maintenance costs on such a thing are, and I didn't really have a clue but figured I could ask some of you good folks online. I think the house in question has a pier with a few pilings for slips, and I think there is a small boatlift as well. I imagine there is some big outlay every 15 years or so to do big rebuilds and replacements, plus some annual work. Maybe the latter is trivial, I don't know. Thanks for any input.
