Share Appraisal Notices Hit Hill County Mailboxes, Property Values Soar Property owners across Hill County should be receiving their new 2021 property appraisal notices from the Hill County Appraisal District. The notices were mailed on Monday, April 19, and Hill County Appraisal District Chief Appraiser Mike McKibben said that for most, the news will be a mixed blessing. "While it is of obvious benefit to own property that is increasing in value, there is also a distinct downside," McKibben said. "As property values rise, more than likely, so do property tax bills. The vast majority of property owners are going to find themselves with higher property values this year."
