Although the beam is a bit narrow for a 30 foot yacht, it looks like it would be an excellent small cruising boat if the pictures do the boat justice. If the boat surveyed well, and won't require lots of additional money to fix it up, it could be a good deal.
When I look at the price
of a yacht, I don't look at the selling price
. I look at the real cost of the yacht after I have brought up to a state that I am happy with. It's easy to buy a yacht for a low price, and then put 5 or 10K into it very quickly. Little things add up.
When I survey
the yacht, I take a pad of paper with me and write down everything that will require money to make it right, or to render it suitable for the intended use/voyage.
If this yacht is in great shape and ready to go, it could easily be worth the price.
