Purchased for $1,635,000 in May of 2014, the two-bedroom Onyx penthouse unit #406 at 415 De Haro Street, in the flats of Potrero Hill, returned to the market listed for $1,735,888 last September, a sale at which would have represented appreciation of 6.2 percent for the well-finished condo over the past 34 months or roughly 2.2 percent per year.

Reduced to $1,695,000 in October and delisted for a few weeks, the “stunning top floor, corner view residence…designed for buyers with exceptionally high standards” was re-listed for $1,575,000 in January, with 1,274 square feet of space, two external storage units and deeded parking for one car.

And yesterday, the sale of 415 De Haro Street #406 closed escrow with an “over asking!” contract price of $1.635 million, the same price which the seller had paid for the penthouse three years ago (and 5.8 percent below its original list price from last year).
