Using Tax Assessments as Appraisal Comps

[Andrew Hoban]

While obviously, tax assessments and home appraisals are two different things, they aren't supposed to be wildly divergent, right? Suppose I'm doing a BRRRR deal and my after renovation appraisal comes back significantly lower (eg ~10-20%) than the tax assessments on comparable properties, can I use that assessment as additional evidence to an appraiser that a bigger value is warranted?
