I’m a bit confused but I’ll go to the SD County assessor’s website for answers. I thought you had to apply for a reassessment by May 30th. We did that and got a letter back agreeing to our request. It was exactly what what we asked for: 20 percent reduction. On the assessment request form, they ask you exactly what you think your house is worth (and comps, as you mentioned). A friend bought a home right at the peak and paid more than $650K. She and her husband also applied for reassesment and said on the form that they thought the house was now worth $400K. I was amazed when she told me the assessor agreed to exactly that amount.
