No idea - I wanted to buy a houseboat years ago but felt too out of my depth (if you excuse the pun) with all the complications involved with mooring valuations, maintenance costs etc. A small part of me still hankers after one - good luck with it!
Ooh interesting! I'm a trainee surveyor and have done a bit of valuation work...
If I was asked to do this I would look for the nearest comparable moorings that you might find prices for. I know it's a new development but are there any nearby or of a similar quality where you can get prices for?
Do you have to pay an annual rent? Or are there any nearby where a rent is paid? If so, an investor would value this by multiplying the annual rent with a yield to give a figure. The yield figure depends on the security of the rent ie a 50 year term would attract a high multiplier making the property worth more.
Sorry, that's explained really poorly so sorry if it's confusing.
I think it will be an annual contract for the mooring that is on offer. So there is limited security and no resale value. However i think it will be the sort of thing where you can roll the arrangement on to the next year if you stick to the rules.
