I'd love to see a high quality golf course with no homes built for $2.5M including land, clubhouse, maintenance facility, grow-in, and equipment that makes $400,000 a year. Especially in Atlanta. I don't think they exist.
I can, however, give you a long list of courses that owners thought would cost $2.5, ended up costing $5.0M, and are making $200,000 per year, which is a scorching 4% return on investment, considering the risk.
Speaking of risk, developing a private club is even riskier.
