Comparable properties do not have to exactly match your property. Look for properties that are most similar, then note their differences and adjust the value of the other property to reflect those differences.
For example, if your property has an obscured view, and the only similar property that sold has a much better view, discount the sale price to the amount you believe someone would be willing to pay for the lesser view. If your property has deteriorated conditions that would make it difficult to sell, provide contractor estimates of the “cost to cure” those conditions. Photos are a particularly effective support for arguments regarding condition. Additional evidence, above and beyond what is required for a complete petition, may be submitted up to 21 business days prior to your hearing.
