Real estate diagnostics for free !
In order to get 2022 off to a good start, for any new EXCLUSIVE sales mandate signed with your GSI agency between January 1 and April 30, 2022, we REALLY offer you the diagnostics necessary for the sale of your property.

The various real estate technical diagnostics required in the event of a sale are grouped together in a single file called the Technical Diagnostic File (DDT). This file must be attached to any promise of sale and to any sale of a dwelling.

Supported diagnostics for sale:

The loi Carrez diagnosis for all condominium lots for residential or commercial use (except cellars, garages, parking spaces and generally lots or fractions of lots of less than 8m²)

The Private Asbestos Identification Report for properties for which the building permit was issued before July 1, 1997,

The state of the Interior Electricity Installation (for installations over 15 years old),

The ERP – State of Risks and Pollution – which since August 3, 2018 replaces the ESRIS – State of Risk Easements and Information on Soils – and adds information on Radon. Since January 1, 2018, ESRIS has replaced the ERNMT – State of Natural, Mining and Technological Risks.

The DPE: Energy Performance Diagnosis concerning all the buildings built,

Operating mode
The diagnoses will be ordered by our agency from our network of referenced partners, paid directly by us. These diagnoses will remain the property of SAS GSI.
