[My question is this - how do you get an honest survey on a surveyor's boat by a surveyor who lives in the same area? lol Sounds like there could be some conflict of interest.
A conflict of interest is when the surveyor owns the boat. Knowing the guy that owns the boat is not. If you are dealing with a professional surveyor then there should never be a problem. Sometimes you buy a boat in a small town and everyone knows everyone. My first one went that way. The surveyor was the best one I ever hired. It cuts both ways and a professional surveyor has to keep a professional reputation or they don't get insurance
business or any respect. It's like hiring a CPA to review some company records. If you fell better you could spend an extra thousand dollars and fly a surveyor in. In the end they never find all the things and you have to have one to buy insurance
I think at this point your list sounds pretty nice. It probably comes down to specific boats and specific problems more than fundamental problems. None of these boats have bad reputations or serious reasons to exclude them only based on the brand name. To be honest I can't think of a long list of boats that only based on the name are "bad".
I would make a list of actual boats that are for sale
in your area. Once you see a few up close and compare the numbers you can tell quickly which are the ones to go after. Making a list of all potential boats then seeking them out is a painstaking process. You can only buy a boat for that is for sale
