Gladys Knight – $720K, Las Vegas

$720K is a lot of money but it sounds like a way-too-cheap amount to pay for Gladys Knight’s Las Vegas home. It turns out a Spanish couple was able to close a very good deal when buying this property, which was originally acquired by Gladys in 1997 for the slightly inferior price of $695K. With 6,500 square feet of space, the luxurious house includes 6 bedrooms, 4 bathrooms, 4 fireplaces, and an open modern kitchen. Additional features include a recording studio, wood-covered ceilings, granite finishing, and an outside pool area.
