Real stories from property owners and residents who trust Sterling150.
"Finally, a property manager who actually answers the phone. I used to dread dealing with my rental properties because something always went wrong and my old manager was impossible to reach. Switching to Sterling150 changed everything. They handle the midnight maintenance emergencies, keep the tenants happy, and my direct deposit hits like clockwork every month. Absolute peace of mind."
"Finding reliable tenants in the Bay Area is stressful, but the team made it look easy. They handled the marketing, screening, and leasing seamlessly. What I appreciate most is their transparency—no hidden fees, no surprise upcharges on repairs, just honest, solid management. They treat your home like it’s their own."
"As a tenant, it’s rare to find a management company that genuinely cares about you. When our water heater went out on a Saturday morning, Sterling150 had a tech out to fix it by noon. They make paying rent and putting in requests incredibly easy. It's truly the best rental experience I've had in years. I can't recommend them enough."

Sterling150 LLC is proudly headquartered at 55 East Third Ave in San Mateo, CA. While San Mateo is our primary hub and area of deepest expertise, we actively manage residential and commercial properties throughout the broader San Francisco Peninsula and Bay Area. We conduct detailed market evaluations to ensure we can provide premier, localized service wherever your asset is located.
Yes. Anthony Addessi and the Sterling150 team possess extensive backgrounds spanning both residential and commercial real estate sectors. For commercial clients, we handle complex lease negotiations, CAM (Common Area Maintenance) reconciliations, vendor management, and long-term asset value protection, ensuring your commercial space remains highly profitable and compliant.
We believe in total financial transparency. Our fees are generally structured as a flat percentage of the monthly collected rent, which means we only get paid when you do. We do not hide behind hidden fees or mark up vendor invoices for maintenance. For multi-unit complexes or large portfolios, we offer scalable, customized pricing structures. Please contact us directly for a comprehensive financial consultation.
Protecting your investment starts with who lives in it. Our screening process is incredibly rigorous. We conduct nationwide criminal background checks, full credit history reviews, eviction database searches, strict income verifications (requiring tenants to make at least 2.5x to 3x the monthly rent), and we speak directly with former landlords to verify rental history. This ensures a stable, reliable tenant base.
We provide a 24/7/365 emergency response system. Tenants can easily submit routine maintenance requests through their dedicated online portal, which allows us to track the issue, dispatch a vetted, licensed contractor, and resolve it promptly. For emergencies (like a burst pipe), our on-call team responds immediately to mitigate damage. Owners are kept informed every step of the way according to pre-approved financial thresholds.
We utilize industry-leading property management software to provide you with an interactive Owner Portal. From there, you can view real-time financial data, monthly cash flow statements, maintenance invoices, and end-of-year tax documents (like 1099s). Monthly owner distributions are transferred swiftly and securely directly into your designated bank account via ACH.
