I can help you out here.
I viewed that boat the other weekend. It's a 50 year old boat. My takeaway was that the engine seemed fair. However it needs new water tanks (currently leaking) and likely fuel tanks. New windlass system needed. Complete renovation inside, heads, rip out the old-fashioned twins in the master stateroom (what is this... I Love Lucy???) and install a queen single. Etc. Rub rails outside were rotted wood. Deck fiberglass needs to be shaved off and redone. I have no idea however of the running gear condition or bottom condition (blisters). Don't know the condition of the genset, but the owner states it runs but is too noisy to sleep with, for airconditioning. The engine room does not have any modern acoustic insulation, so you'll need to do that.
Very much a project boat. Even if you do all the work yourself you'd still be in another $50k on top of the purchase price.
Or you can just buy it cheap as it is, put zero dollars into it, and just use it for a couple of years as a fun big pile of junk like the current own has been.
Don't mean to bust your dreams, but just offering you a reality check.
