2025 price evidence
What the property mix changes
The 2025 median house sale was 41% above the flat median, while the house median per square metre was 24% below the flat figure. This is a comparison of two different groups of sold properties, not an estimate of the premium for converting one property type into another.

How to read the evidence
How to use this evidence
Start with a question, not a single headline number. For Brittany, compare the same property type and time period, note how many records support an aggregate, and treat a regional median as context rather than a valuation. A large source count improves coverage but does not remove differences between communes, condition, land, tenure or unusual sales.
Questions this page can answer
What market evidence is available?
The page identifies the aggregate DVF coverage for Brittany, including the relevant years and number of source rows.
How should two areas be compared?
Use the same property type, period and calculation, with sample size visible. Do not compare unlike regional definitions as if they were one market.
What risk context is available?
GASPAR provides commune-level screening context where shown; it is not an address-level determination.
What must be checked before acting?
Verify the precise property through the notaire, Géorisques, planning records, diagnostics and an appropriate survey. This site deliberately leaves unknown facts unknown.
