Lancaster county property owners have been receiving their new assessments in the mail this week!My own home went up $10,000 in value. So be it as I think they had it pretty low! But my 2 rentals are another case! They both increased about $15,000 and I don't believe I could get the old assessed value if I sold them now.Oh dear, what to do!. You can protest in the month of June but you will need supporting documents such as a purchase agreement or appraisal to make head-way. Good luck, property-owners!!
