This gem would be MINE! All mine. This is an impressive house mansion. I can't figure out what's more amazing: the price, the location in Dupont Circle or the fantastic interior. This is 1824 R St, NW. It has eight bedrooms, nine full baths and two half baths. It's 10,000 square feet, has an elevator, an outdoor terrace and a five car garage and it's listed for $15,500,000. Of course, this beauty is appointment only.
