I've offered to inspect boats for sale in my area for distant buyers, by contacting the broker and requesting a walk-through.
I did this twice for internet friends, was upfront to the broker with my intent, which was to have a preliminary look - poking into bilges, taking photos and generating an overall assessment of the condition - not necessarilly evident in the online listing.
I emailed my opinion with the pics, so the potential buyer could decide if the expense of traveling the distance would be worthwhile. Naturally, hiring a surveyor as the next step is not recommended, which should be done only upon an actual inspection by the prospective buyer.
