Billy showed us at least two dozen houses in the Rittenhouse area, many on short notice from us. We used those visits to focus our needs and to pick up useful knowledge from Billie about neighborhoods within easy walking distance from the square. He was unfailingly responsive, always pleasant to work with, eager to help us evaluate each place we looked at. When we finally decided what to buy, Billie negotiated a favorable adjustment in our offering price with the seller. Not incidentally, he returned our calls promptly. I recommend Billy Grewal without reservation.
