• This million-dollar New York Ave. NW townhouse, whose notoriously botched 2014 renovation caused it to collapse and block traffic for days. [Redfin]
• This Washingtonian “Listing We Love,” a $6 million, 6-bedroom Georgetown house with a solarium, heated pool, and brain-melting wallpaper. [h/t Washingtonian]
• A $280,000, 467-square-foot Dupont studio. [h/t PoPville]
• This $950,000, nearly 11,000-square-foot lot on Mississippi Ave. SE in Congress Heights, zoned MU-4 for mixed-use residential development. [Redfin]
