I know you've spent some time up here digging around the market. Did you find any houseboats that would work for you? I think a lot of people have trouble realizing that these are waaaaaay more house than boat. Whether that translates into a rent premium is what started this whole forum thread and still up for debate.
Yep. I was up there a week ago and will be putting some offers on a few houseboats pending an inspection. Buying these things is a lot like buying a collectible car. They are all very different, replacement parts can be a headache, rust is an issue, and values swing wildly up and down depending on the type of owner you're doing business with.
From a buy and hold perspective, houseboats usually don't make a lot of sense, although there are some exceptions to the rule, just not in Portland. The rental value is also iffy, when you consider the amount of maintenance, and in Portland the houseboat communities aren't where the higher rents are.
There IS, on the other hand, a market that houseboats work in. A couple of former partners and I have just started a new venture using a nightly/weekly/monthly rental formula. The numbers add up quite well when marketed and managed properly.
Ask me in four months how well it's working, I will be happy to share my experience.
