Trusting a "Recent" Survey?
I've been reading that the cost of a survey is usually borne by the buyer, yet I sometimes see ads for used boats claiming recent survey done, and so I wonder why the seller would be in posssesion of the survey? Someone flipping the boat, or, is it common practice in order to reduce the cost of multiple surveys that the prospective buyer offers to split the cost with the seller?. A survey in the possession of a buyer who didn't purchase is pretty much a useless piece of paper, but could be helpful to the seller for the next prospective buyer (provided survey is favourable or repairs have been documented as being completed), or for renewing insurance perhaps?.
Also, if a seller has a survey, how recent should it be to be considered trustworthy by the prospective buyer- for insurance purposes and to save commisioning a new survey?
Thanks (sorry for the muddled wording)
