Calculations are based on property listings that exist within Southwest Florida MLS. Only properties in Collier County, excluding Marco Island, are included. *Counts for breakdowns of available inventory for prior years are unavailable. **Median Sold Prices are unavailable for periods with zero sales reported. In order to compile congruent data from multiple sources under the new Matrix system, a new method of calculating days on market was adopted. Therefore, historic comparisons of this data will be released when adequate time has elapsed allowing for such comparison. The median refers to the middle value in a set of statistical values that are arranged in ascending or descending order, in this case prices at which homes were actually sold. Data entry anomalies and non-Naples zip codes may result in minor discrepencies. However, these anomalies are statistically insignificant. Single Family Homes are tabulated using properties with a building design of Single Family, Villa Detached, or Manufactured. Condo units are tabulated using properties with a building design of Low-Rise, Mid-Rise, High-Rise or Villa Attached.
