^^^ this is a good list.
I get to about the same place by a slightly different thought-path. My triage model is
-- structural issues? are there significant ($$) issues in hull, deck, core, internal structures, rig, evidence of water ingress, etc? unless you're looking for a project boat, those are probably deal-breakers
-- systems issues? engine, steering, electrical, potable water, etc? May be major, may be manageable, but you definitely want to know about them in order to make an informed decision
-- maintenance issues? stuff needs re-bedding, sails are old, rigging is worn out, engine is rusty, hoses are crusty, cushions need recovering, interior/exterior wood needs work, gelcoat has scuffs and stains.... These can be pretty "normal" for an older boat, but can be indicative of the quality of care the boat has received.
-- upgrades and mods? new-ish electronics, well-installed can be a plus. 1980s instruments, mounted either side of the companionway, all at different angles (I've seen it)... ugh. My OCD kicks in and starts thinking "that's a $5,000 project to undo it and do it right" Same for "remodeling" the interior to suit an esoteric use-case. If the stove has been taken out and replaced with a countertop butane burner, for example.... it can mean there are significant issues somewhere else.
-- cosmetic issues? probably should be the lowest priority in terms of deciding whether or not a boat is "the one". Unfortunately, many buyers put "oh, she's pretty" on the top of the list and forget to really notice the other things.
