We live on roughly 1000 sq ft lot in an older three bedroom, two bath home without a lot of amenities inside or out. The neighborhood is mostly well kept but is an older neighborhood of not what you would call high value homes.
Zillow estimates the value of our property at $500,000. That's way high but at least gives a marker to start from.
When you figure Mar-a-lago is 20 acres (871,200 sq ft), has a very large exquisite building on it plus other structures, a well kept golf course, beautifully landscaped, magnificently appointed and maintained, located in one of Florida's highest rent districts, I think most of us couldn't imagine what that would be worth to a buyer with unlimited cash.
