<prompt> Human: Will this matter at all when I try to sell? Is it worth it for me to protest, even if it means my property taxes wont decrease?  <response>: Its just your tax assessment. Your property taxes will decrease next year. Challenging the assessment by asking for a higher valuation will likely be a source of humor for your tax assessment board.It _may_ have an impact on your sale value, but unlikely unless assessments are done regularly and other properties around you did not change.I can tell you that assessment is almost a joke where I am western PA, except the once-every-several-dozen-years that its done and everyone complains when their property taxes go up 40. When I bought my house, it was valued at something like 60k. A year later, the county won a court case against the state that allowed them to re-assess. My assessment when up to 100k. That was not a fun year.Best bet? Ask a Realtor.
