This baroque 8th-floor penthouse condo in the Campton at Post Oak building at 4950 Woodway Dr. north of the Galleria has been available for rent at $9,500 a month since last September (marked down from the whopping $11,500 it began with in August). But there a few things you might want to know about the 3,948-sq.-ft. pad before you sign any lease: First, the unit’s owner since 2010 is Minnesota Vikings running back Adrian Peterson — who (in case you’ve been on a news blackout for the last several months) last November pled no contest to charges of “recklessly assaulting” his 4-year-old son with a wooden switch, and was suspended from the NFL for the remainder of the season. Second: Peterson hasn’t been paying his taxes on the property; after court proceedings at which Peterson failed to appear, a tax auction was approved by a district court a few days before Christmas.
