Expert
assessment

Any real estate agent can make a valuable opinion, but only an Appraiser can make an estimate of market value.

The valuation expert applies engineering methods that require a correct diagnosis of the valuation or depreciation of the real estate and must be both:

Technician to make a technical judgment of the value (type of construction, architectural quality, condition of the building and equipment, etc.).
Economist: the exchange value of a good also depends on the supply and demand (thus the economic context) as well as the technical qualities of the good.
Lawyer: the expert must have knowledge of private law (easements, rent law, etc.) and public law (town planning law, expropriation law, etc.)
Tax advisor: the expert must keep abreast of the tax regulations and its evolutions in order to assess their impact on the functioning of real estate markets.

A Real Estate Expert may act as part of an amicable expertise, or as part of a judicial intervention and is then appointed by a court to which he is accredited.

The Expert can intervene to fix the market value of your property in the following situations:

Sale or purchase real estate
Mortgage: Mortgage guarantee
Succession, donation, sharing
Liquidation of community of property
IFI statement
Expropriation
Fixing or revising of a rent
Tax adjustments
Eviction procedure
Evaluation of a rental value
Etc....

In any case, an expert in valuation of market value will intervene only within the framework of a signed mission order after acceptance of a written cost estimate.
