About Us
Meet the Team
Our services are provided by highly educated licensed professionals with extensive experience in real estate investments and property management, as well as the related fields of tax and accounting.
Our tax and accounting backgrounds have taught us that it’s all about the details, down to the penny. Many property management companies overlook the little details, or ignore what they perceive as burdensome rules and regulations. That’s not our style. These kinds of oversights can, and often do, lead to increased expense and liability for property owners. We pride ourselves on the attention we pay to details, which sets us apart.
