I use three approaches to assess value:
Sales Comparison – Compares your property to similar homes that have recently sold, adjusting for any differences in size, amenities, etc.
Cost Approach – Values a property by determining what it would cost to replace the improvements, subtracting any deterioration or depreciation from that, and then adding the value of the site.
Income Approach: Estimates what an investor would pay for a property based on the income it produces.
