Condominiums can usually be valued quickly using the sales comparison approach due to good comparable data availability, which reduces the time required and thus the costs.
For single-family houses, the land often has to be valued separately and a more detailed property inspection is required, which is reflected in the higher fee.
The specific costs also strongly depend on the intended purpose: an appraisal report of court-standard quality for inheritance or divorce matters is more elaborate than a private condensed appraisal report.
Location also plays a role: in regions with sparse comparison data, such as rural areas, the research required for additional comparable properties can increase the effort for both types of property.
A non-binding preliminary estimate of the expected costs can usually already be provided during the initial consultation based on the key data of the property.
