What about operating in bigger markets, like cars, trailers, RV's, etc. ?
Or are those markets too competitive? Having sold cars on Craigslist before, I know that there are people who are offering low values, fast sales, shortly after posting in hopes of finding a desperate seller, so maybe these people make profit much less likely for a trader.
Laws vary, but you can only flip a few cars a year, like a dozen or so, before you're required to get a dealer license. These generally cost thousands of dollars a year and come with a lot of paperwork overhead.
