There are no very specific regulations for carrying out agricultural appraisals in Costa Rica, except for the accounting standards and the considerations of the financial institutions if they request them based on internal regulations (manuals).
In case that these property valuation reports are required for other purposes, they must comply with the respective regulations, as in the case of appraisals for agricultural surveys, expropriations, etc.
The more complex the property, the more there is to know. With a farm, you are dealing with many acres of land. A dairy farm is different from a timber conservation farm, for example, and that is why various aspects or factors that intervene in the approach of each farm must be considered.
