As devil's advocate, if EBIT or EBITDA were negative or just slightly positive (as in a new course or one which requires repositioning membership) this wouldn't give a fair value. On the flip side, you can't pay for "blue sky" (potential future earnings) either. Given the current market 6x EBIT is the maximum one can play and still service the amount of debt required to leverage the deal (if one can find a lender willing to give about 50% of the negotiated sales price).
Buying a golf course asset to reposition it to another use is land speculation, not even land evelopment and is risky for all but the most seasoned or iron willed investors.
Run the numbers on what reasonable expected revenues would be, what it would cost to operate the facility annually, then throw in real estate taxes and long term equipment leases costs. What is left is Net Operating Income (NOI), of which you can use about 70%-80% of to service your debt, which tells you how much the bank will lend you and how much equity (your money) you need to put into the transaction. If everyone is comfortable with the numbers, you can make the deal, if not keep looking, its real estate, there's always another deal out there.
