We believe we are your source for assessing solutions because we are flexible enough to encompass your needs while remaining stable in all environments.



Patriot Properties, Inc. was incorporated in May of 1985, founded by a group with vast experience in the appraisal and revaluation field. The founders had several principles on which the new corporation was founded which separated it from other companies. Aside from a dedication to timeliness & quality work, the owners of the company all work directly on client projects. This philosophy results in more responsiveness to client needs and closer application between the client and corporate objectives. Patriot Properties, Inc., developed a new state-of-the-art "CAMA" software system, which accurately fills the needs of county and municipal clients. This CAMA system has evolved and been refined over the past 34 years. The data processing staff works closely with the project supervisor and client to customize software products for each installation. Data processing conforms to the project's requirements, not the converse. These two (2) differences make for a highly sensitive and responsive environment for the client.

In the 34 years since the founding, Patriot Properties, Inc., has installed software or provided services for over 200 counties or municipalities. The company's original CAMA system was a multi-user DOS based assessing system developed in 1985. In 1995, a Windows® product, AssessPro for Windows, was released and is now the primary product in the Patriot Properties' software line. As Patriot Properties celebrates its 30th year of incorporation, CollectPro, our billing & collections application has been an increasingly important addition to our product line.

Patriot Properties, Inc., has been in business over 30 years and serves more than 230 clients Nationwide with a staff of 55 employees. Quality control by the working partners has remained a constant priority since the company's founding. We have toll-free "800" telephone lines to our fully staffed technical support group from 8:30 a.m. - 5 p.m. Monday through Friday. We provide unlimited toll-free support. We pride ourselves on our level of customer satisfaction and our timely response to client needs. This support function, however, is made easy due to the ease of use of AssessPro.

In our years of service to government, Patriot Properties, Inc., has converted data from dozens of different assessing systems and has interfaced with more than 25 different tax collection systems and numerous other Governmental Software Applications.
