Pretty brisk business in the brownstone neighborhoods and a head-scratcher in Manhattan Beach.

This 4,100-sf townhouse was originally listed for $4.5 million in February, according to StreetEasy. Asking dropped by a quarter mil about 5 months ago. House has two units, one of which is a 5-bedroom triplex. Deed recorded 9/02.

2. MANHATTAN BEACH $3,050,000
150 Hastings Street GMAP (right)
3,532-sf house on a 6,000-sf lot half a block from Manhattan Beach Park. Property Shark records show it last traded for $800,000 in 2005—quite the meteoric appreciation.

3. BOERUM HILL $2,700,000
253 Dean Street Street GMAP
20 ft x 42 ft townhouse with an owner’s triplex and rental unit. The property sold quickly: It was listed for $2.495 million in late May. The Los Angeles-based person who signed as a trustee for the purchase has the same name as someone who’s reportedly dating a star of the TV show “Grey’s Anatomy.” Coincidence? Deed recorded 9/03.

4. CLINTON HILL $1,895,000
298 Lafayette Avenue GMAP
3,496-ft, 2-family house priced at $1.995 million when it was an Open House Pick this May. Deed recorded 9/03.

5. CARROLL GARDENS $1,830,000
16 4th Place, Unit 1 GMAP
Triplex condo in a 19th century townhouse. Listed in April for a hair above the closing price, according to StreetEasy. Deed recorded 9/02.
