Years Of Experience in Real Estate
A family legacy of dedication and innovation
At Cornerstone Real Estate and Home Loans, our journey began with a vision to transform the real estate industry by uniting all aspects of property services under one roof.
Founded by Carmen Rodriguez and her son Joel, our Vacaville-based team has been assisting clients with the care and dedication of family for over 50 combined years.
1988
The Beginning
Carmen Rodriguez, inspired by her father, her faith, and her journey as a young immigrant, obtained her real estate license.
She quickly built a reputation in the industry for putting her clients’ needs first, guided by a commitment to respect and exceptional customer service.
2003
A Pivotal Year for Joel
Joel obtained his Salesperson license and began working alongside his mother, Carmen, at Century 21 as a Realtor.
Recognizing the opportunity to support Carmen’s clients, Joel transitioned into the mortgage industry, bringing his expertise to enhance the services Cornerstone offers.
2004
Cornerstone is Born
Carmen and Joel founded Cornerstone Real Estate and Home Loans with the goal of creating a seamless, one-stop-shop for real estate and mortgage services.
This innovative approach was designed to provide a smoother, more efficient process for all their clients.

Expanding Expertise
Maggie, Joel’s wife, joined the Cornerstone team as a mortgage broker, strengthening the company’s comprehensive services.
After a period dedicated to raising her family and earning a psychology degree, she returned to contribute her unique blend of industry knowledge and academic insight.

Establishing a New Home Base
Cornerstone purchased a building in downtown Vacaville at 543 Merchant Street, symbolizing the company’s growth and dedication to providing top-notch real estate and home loan services to its clients.
