DwellingCost.com is a developer of tools and data sources for real estate professionals. The concept behind DC was born out of the dissatisfaction that a group of appraisers had with the sources of replacement cost data available to them. They felt that the current services were not refined enough in specific geographic areas and that the levels in quality ratings were too broad. So they embarked on a journey to develop a cost service that would better serve the needs of real estate and insurance professionals.
