This is when the appraiser, drawing on all the work done, applies professional judgment to reach the property's market value.
Consolidating the information
Before setting the final value, the appraiser reviews the inspection data, the market analysis, the researched samples and their unit values, the homogenization, and the simple and weighted average calculations.
Calculating the appraised value
Appraised Value = Unit Value × Reference Area
- Land — total lot area.
- Urban built properties — private or built area.
- Rural properties — total or usable area.
The PTAM presents the central value and a range representing the reasonable negotiation interval. The adopted value must be technically justified, explaining the chosen unit value and how the property compares to the samples.
Reference date: the value has a limited validity over time. The document must state the inspection date and the issue date, and it is recommended to use it within a reasonable period — generally up to 6 months.
