The nationâs second fastest-growing county will see a double-digit rise in property values for a fourth straight year. The Comal Appraisal District, which assesses and certifies values of taxable properties for 32 taxing jurisdictions in Comal and adjacent counties, predicts 2021 values will rise between 14% and 19% over last year, based on assessments as of Jan. 1, 2021. âThis is the fourth year weâve seen double-digit increases,â Rufino Lozano, CAD chief appraiser said. Lozano said more people and fewer available homes and businesses fueled market values even before COVID-19, bolstering what has long been a sellerâs market. âThey are getting whatever theyâre asking for, and in some cases even more,â Lozano said. âThat was the case for 2020, but weâre definitely going to be looking at doing something different for 2021.â
