Perhaps an unfamiliarity with the real estate market in Prospect Lefferts Gardens is what led to not a single correct guess for this week’s Pricespotter apartment, a one-bedroom duplex on Hawthorne Street. The asking price: $835,000. The closest guesses: $830,000, from BK1985. For that price, a buyer would get more than 1,200 square feet of space, split up into a ground-level rec room, and an upper-level floor with a kitchen, bedroom, and living room. There’s also a bit of outdoor space. Common charges are $570, and it’s under the 421-a tax abatement through 2026.
