According to Gilbert Davila, principal at Popp Hutcheson PLLC, an Austin-based law firm specializing in property taxes, the hikes are primarily attributable to basic increases in construction and investment in self-storage properties across Texas. Based on how pricing for commercial real estate in Texas has generally skyrocketed in recent years, appraisal districts are now able to derive very low cap rates for many of the properties they assess. In addition, Davila says appraisal districts are only just beginning to have access to comprehensive data to use in valuing properties in this sector. "Prior to the last couple years, appraisal districts weren't very aggressive on self-storage owners, and now they're playing a game of catch-up" he says. "However, we should be past the worst of the exponential increases and should see more stagnant property tax valuations for the year 2018."
Davila also points out that many self-storage owners are now protesting their assessments in court. Because Texas law requires all properties within a certain jurisdiction to be assessed equally and uniformly with facilities of similar sizes, this litigation should help lower the median level of valuation for self-storage assets.
