You know that brownstone prices in this neighborhood have skyrocketed in the last several years, and so have rents — a fact that you might appreciate as the owner of this “classic” five-story townhouse currently configured with two “high income-producing” rental units. Of course, if you prefer, you can convert the home — located on Sixth Street just “a few steps” from Prospect Park — back to its circa-1900 “late Romanesque Revival” glory as a single-family mansion. It features four parlor floors, “grand-scaled” rooms (including 10 bedrooms and six bathrooms among its 4,788 square feet), “soaring” ceilings and original architectural details. There’s also a “deep” garden, two decks and a full cellar.
