Yes, that's a putting green in the photo. I took the photo this weekend as I was viewing a home. The seller loves golf so much that if he misses a day, he has his own practice range in the backyard.
More and more, sellers are turning their backyards into more than just some pretty landscaping and a pool. Owners are looking to make the land "theirs", either through golfing, rose gardens, swimming ponds, Japanese rock gardens, etc. If you have the acreage, I have seen shooting ranges, horse pastures, extravagant fire pits, and dirt bike trails.
But the main goal is to actually use the land for something the owner can enjoy. Too often, backyards become just a green grass landscape. Take hold of your backyard and turn it in to something extraordinary...like a putting green!
