Financiers continue their relentless creep into the formerly creative neighborhood known as the Upper West Side.

The late writer (and rabbi) Chaim Potok’s one-bedroom, one-bathroom apartment has just sold to a finance type.

The charming home takes up a full floor in a brownstone at 136 W. 81st St. Located by the Museum of Natural History, it features 11-foot ceilings, lots of light and a working fireplace. The buyer paid its full asking price of $615,000.

Potok was best known for “The Chosen,” a New York Times bestseller, which was published in 1967.

The seller’s brokers were Andreas Mann and Bradley Miles, of Douglas Elliman, while the buyer’s brokers were Elliman’s Andrew Anderson, Bruce Ehrmann and Christopher Morales.
