Real Estate Valuation Experts


The real estate valuation expert is a technical specialist who searches for value. Rather than acting in the market, we observe it.

The Code of Commerce is an economic law; it is not a social law like you find in housing. This gives landlords contractual freedom when setting the initial rent, fees and conditions.
This is the paradox of commercial real estate law: rather than protecting the user, the Code of Commerce protects the property rental business. It protects the capital represented by the premises, hence the importance.
Real estate valuation experts frequently intervene during lease renewals, either to establish the rental value and search for potential grounds to lift the rent cap, or to determine the amount of eviction or occupation compensation due.
