It sounds like you worked the numbers and it worked out for you. I'd say it makes sense.
I was paying $2150 for a summer slip in a working boatyard with no amenities. It was a realtive bargain. Winter storage which had to include everything involved in winterization, covering, bottom painting, haul, and re-launch was about another $3900.
The owner of the boatyard was pretty good about letting me do other maintenance or small repairs, which is unusual for around here, but anything else had to go through him. Anything that required an outside contractor had to be one of the people he uses. They were all good people, but charged extra becuase they had to kick back to the boatyard for coming in there.
I bought a piece of property last year for $60,000. The taxes are $700. The water and electric bills will be about $300 for the year. It cost me $270 for shrinkwrap, $270 for a crane to pick the boat up and block it up on the property, and another $270 to put it back in the water.
I figure the cost of all the supplies for winterization, bottom painting, and zincs to be about $400. I do the labor, which I wasn't allowed to do in the boatyard.
Figure in other incidentals and I'm looking at about $2500 a year to dock, winter store, and maintain the boat. That's a savings of about $3500 a year.
Not a bad rate of return on a pretty secure investment. Much better than I could get anyplace else.
If the property increases in value during the time that I own it, the return increases. Chances are good that it will increase because they aren't making any more waterfront property around here, and many marinas/boatyards have already sold off to residential developers over the years, with more likely to do so in the coming years.
If the boat needs any repairs that I can't handle, I can use anyone I want to do them. That increases the savings.
I had been looking for a piece of property on this particular canal for a few years and jumped on this one as soon as I got word of it. In all likelyhood, if I wanted to sell, someone would jump on it just like I did.
Had I not come across it, I was ready to by a dockominium in a local place.
The initial purchase price was lower for the dockominium, but the annual expenses were just slightly higher. They also let you bring in people from the outside for repairs or maintenance, but they have to be approved. Not a big deal, and probably a good thing so you make sure that competent insured trustworthy people are walking around in the marina. Overall, the numbers still worked out to be much better in there as an owner than anyplace else around here as a tenant.
It probaly varies from one region to the next, it sounds like price and availability of dock space and storage is very different in different areas of the country, but if you sharpened your pencil and the numbers worked out, then go for it.
