The main purpose of the VA Appraisal Modernization Act is to improve the process and fees associated with appraisals for housing loans that are guaranteed by the Department of Veterans Affairs (VA). The act aims to ensure that appraisal fees are fair and reflect current market conditions, particularly in areas where demand for appraisals is high or where appraisers are scarce. Key provisions of the act include the establishment of a new section that defines appraisal fees and introduces annual adjustments based on home price increases.
