For Del Cerro, I’d suggest Kassy Kaiser, who has been “farming” my parents in Del Cerro forever. She knows the territory. La Mesa, Stan Sexton, although I believe he’s been maligned on OCrenter’s blog. We live in La Mesa (third home) and used Stan as our buying agent in either 86 or 87 for our first home. No problems. We did the last two sales on our own. Google for contact info.
