From Rent Ready to Rent Profitable

Your property. Our priority. Communication that delivers results
Why Hire Us

Property is more than just bricks and mortar—it’s a reflection of hard work, aspirations, and the foundation of your financial future. You face real challenges as a property owner: concerns about maximizing cash flow, placing qualified tenants, and avoiding hidden fees. Too many property owners lose precious time, money, and opportunities because they’re stuck with subpar management or are overwhelmed by doing it all themselves; can you imagine the weight lifted off your shoulders if you no longer had to field late-night tenant calls or navigate the maze of Texas rental laws?

 Imagine partnering with someone who not only understands the complexities of property management, but also shares your commitment to creating a life of abundance and security. Well, we’ve built our business on solving these pain points with precision, care, and dependability.

I’m Bobbye Joe McMillan, owner of Cornerstone Property Management, and for over 30 years, my team and I have been helping landlords and homeowners like you build and maintain wealth through real estate. As a San Antonio native and a mother of four, I’ve rooted myself deeply in this community, cherishing the values of hard work, trust, and family. Beyond managing properties, I serve as a dedicated advocate for landlords, bringing my expertise to the Property Management Committee for the San Antonio Board of Realtors. This role allows me to stay ahead of industry trends, ensuring our clients benefit from the best practices and strategies in property management.

What sets us apart is not just what we do, but how we do it. From finding great tenants at full market rent to managing maintenance and paying you on time every month, we handle every detail with professionalism and care. Our pillars—communication, experience, and dependability—ensure you’re always informed, confident, and stress-free. We know your property isn’t just an investment; it’s a cornerstone of your legacy. That’s why we approach every relationship with integrity and a laser focus on growing your wealth while protecting your assets.

Let’s build something extraordinary together. Schedule a 1-on-1 strategy session and take the first step toward financial freedom today.
