How we work.

1 We work closely with the client to define the appropriate scope of the assignment. We are dedicated to providing the best appraisal product to fit our client's needs, with the utmost competency, integrity, and without bias. No matter how big or small the project is, we have years of experience in performing the appraisal on time and on budget.

2 With a strategic relationship with a national data provider, we are able to quickly gather the necessary data to perform the appraisal, no matter where it is located throughout the country. Through on-the-ground inspections, analysis of local data and consultation with local experts, we gain the geographic competency to understand the market and perform the appraisal. Through the use of GIS, we are unmatched in our capabilities to perform large, multi-county/state assignments.

3 We work with our clients to determine the end-products that are required. We pride ourselves in providing clear and concise appraisal reports, whether it is a summary or full narrative report. With our mapping capabilities, we are able to provide detailed maps, whether contained within the appraisal report or in a separate mapbook, depending on the needs of the client. Our clients are provided an appraisal report that leaves no question as to scope, presentation of data, analysis and our opinion of value.
