Value of a 1,300+ site park

I’m Steve, a commercial real estate appraiser working on valuing a couple of mobile home parks in my area that are each over 1,200 MH sites a piece in South Florida. I’ve been doing some studying on economies of scales adjustments per site and even expense ratio and cap rate considerations for such a large site. Has anyone here had experience, possibly from an investor’s point of view, of purchasing a 1,000+ MH site park? Any thoughts or general rules of thumb that purchasers of such large parks would take into account. Any thoughts that you might have, I would be more than happy to receive for consideration. Thanks for your help.
