Airbnb on leased land? Financing options

[Rivers Ford]

So I’ve got an amazing Airbnb property that I’m looking to purchase. It’s priced about 200k lower than its comparable properties but it’s in a campground where they lease you the land. This property will cash flow about 70k a year in my area as I’m at the beach and this campground has mini golf, water park, etc. my lender tells me it’s impossible to get financing for this even with portfolio lenders he knows and the only option is to purchase with cash which unfortunately is not an option for me. Has anybody ran into this or know what next steps I should take. By the way my lender is a rockstar and has several short and long term rentals.
