LOSS: BEYONCE'S MOM Sells Texas Mansion at $500k Discount

Beyonce's mom really wanted out of her Texas-sized Houston mansion, so much so, she was willing to knock $500,000 off the listing price to get it sold, TMZ has learned. We broke the story ... Tina Knowles tried to unload her 8,885-square-foot pad last September for a whopping $3.499 Million ... but it sat on the market for nine months with no takers. She finally sold it this summer ... but for a whole lot less than she planned, accepting an offer of $2,962,500.
