A sprawling 25,000-square-foot residence in affluent Saratoga Springs, N.Y., will be auctioned later this week through Platinum Luxury Auctions.

The reserve price is $4.9 million — not bad, considering the mansion was recently offered for $8.6 million. The five-bedroom home sits on eight acres.

It includes, well, everything: indoor and outdoor pools; fitness center with sauna; indoor basketball court; a multi-row home theater and a one-lane bowling alley.

If those don’t seal the deal, then the eight-car garage, tennis court and 1,200-square-foot guest house on top of it all will.
