Great topic Craig66.
Your suggested question
as below is what all buyers should ask - but maybe not for all the categories you have listed...........of course it depends on the $value of the yacht...............a Cav30 in the $50k range was the most I got to buy and sell............
If you were to keep the boat what do you foresee needs to be attended to?See useful links here - there are many other links obviously.

Of course could add heaps more..............
Standing rigging renewal - what wire was used (standard 316ss or a compact wire such as Hammapro), and were the diameters and breaking loads equal or greater than the original, including turnbuckles etc. Any standing rigging damage from unexpected events - ie complete knock down of the boat from a murderous gust and mainsheet not able to be uncleated, or forestay turnbuckle bend due to hitting a wharf just above bow height............are the chainplates of suitable load rating, and the bulkheads they are bolted to of same rating, no wood rot in the bulkhead or corrosion in the chainplate bolts. Same for forestay and backstay securing.
Mast - how old. Any galvanic corrosion holes under stainless bands (gooseneck, kite pole snotter, spreaders, other). Such corrosion is a big kahuna if the Duralac usually used in older masts breaks down........Tefgel is the go now. Is the mast straight laterally, and with a fair continuous curve fore and aft - assuming a swept back spreader fractional rig. Masthead crane ok? Mast at base not showing buckling signs? Mast base to deck ok, secure.
Hull - do you mean ingress not egress?
Hull above waterline - cabin top handrails fitted and load rating as designed? (Many teak handrails on older yachts are way beyond their use by date........). Pulpit, pushpit, stanchions and lifelines ok? Secure? Not bent? Many yachts have bent stanchions due to prior close encounter events.........these are easily straightened at numerous pipe rolling companies around the country - they have the formers to ensure the tubes don't get damaged in the process ........hatches not damaged and sealing? Companionway hatch secure and sealing? These are easily fixed.
Hull below waterline - osmosis..............is there any............see prior threads this may not be a show stopper if it is slight but if it is rampant then walk away.....................skin fittings - must be marine bronze suitably sealed / adhered in, with marine bronze valves attached then double ss utilux clamp reinforced hoses onto the valves. Hull floors in way of keel - lateral and fore and aft structural grid, any crazing of the grp. Any grounding events and consequences to the hull structure.
Most buyers as a pair - him and her - want a proper toilet with pump out to holding tank included, and hot shower. For the Cav30 I bought / sold this could have been fitted but wasn't.............for the 2 Santana 22's I bought / sold this wasn't possible obviously...........not sure why persons who are only going to day sail a yacht are obsessed with bathrooms............so use the one you have at home then go sailing...........return home and use it again..............not rocket science.............
