Our Story

Located in the heart of San Mateo at 55 East Third Ave, Sterling150 LLC was founded on a singular vision: to bridge the gap between high-level real estate investment strategy and boots-on-the-ground property management.

The Bay Area real estate market is notoriously complex. We noticed that property owners were often forced to choose between massive corporate management firms that treated them like a number, or smaller operations that lacked the financial sophistication to truly maximize ROI. Sterling150 LLC was built to provide both.

Today, we manage a diverse portfolio of residential and commercial properties across the Peninsula. We treat every asset we manage as if it were our own, deploying strict preventative maintenance schedules, rigorous financial accounting, and aggressive marketing strategies to ensure our clients' investments remain profitable and secure.
