As appraisal companies and mortgage servicing firms gather in Grapevine, Texas, for the Mortgage Bankers Association‘s National Mortgage Servicing Conference & Expo this week, appraisal firm Coester Appraisal Group is announcing the development of a smart phone app that will allow appraisers and servicers the convenience of checking home appraisals through smart phone devices. Rockville, Md.-based Coester Appraisal Group said the app is in the beta testing phase and will be available free of charge later this year. The app will work with multiple operating systems, making it compatible with Apple iPhones, BlackBerrys and Google Android systems.  Through the solution, servicers and appraisers will be able to order and check appraisals by simply accessing a direct link on their smart phone devices. With the Dodd-Frank Act expected to be a hot topic at this week’s conference, Coester is toting the app as an affordable solution to Dodd-Frank reforms that will require “customary and reasonable” appraisal fees.
