How do you mitigate against the risk of a huge property tax increase? The property I’m looking at won’t get reassessed just because it sold, but the county could theoretically call for a county-wide reassessment any time. This property hasn’t been reassessed in 30 years, and the assessed value is extremely low. But I assume the assessed values of all the properties county-wide are low, relative to their market values (since they haven’t been reset in 30 years). So how can I predict what my taxes will go up to if/when the county does reassess?
