For example, if you have some awesome vintage furniture inherited from your grandmother sitting in a storage unit, you can rent this out to photographers for their “styled shoots” which are becoming all the rage. If your furniture is more modern but you still can’t bear to get rid of it – perhaps a home stager will be interested.
Obviously with such a hugely valuable niche where people will be spending on average around $30,000 to $60,000 on a boat, there will be tons of information and reviews available, right?  Wrong!  In fact, MOST of the boats that I was interested in had zero reviews to be found anywhere on the internet.  Zero.  And all the manufacturers showed was a few pictures, sometimes a sales video, and an abbreviated spec sheet.  That’s it.  I scoured the internet for unbiased reviews of boats and did not find anything helpful at all.
