How is the renovation potential of Witternheim computed?

From 100% public data: DVF property transactions (DGFiP), Filosofi incomes (INSEE), SIRENE business fabric. No personal data, no individual property valuation — a reading of the town-level market.

What does the energy-sieve letting ban change?

The French Climate Act progressively bans letting the least efficient homes: EPC-G since 2025, F in 2028, E in 2034. Affected properties trade at a discount and represent high-leverage renovation stock (MaPrimeRénov', energy-savings certificates).

Is a discount vs the department always an opportunity?

Not on its own: a lasting discount without market momentum or local demand can signal decline. It is the combination of discount + re-appreciation + solvency that distinguishes renovation potential from a merely depressed market.

Why Witternheim can be renovation ground

A town discounted versus its department, whose property market is re-appreciating and where local income can fund the works, combines the three conditions of profitable renovation: a low entry price, latent post-works upside, and local demand able to absorb a renovated home. The letting ban on EPC-G homes (2025) then F (2028) accelerates this stock.

Method: what the score measures

The score combines property discount (DVF DGFiP, town median price vs department median), 3-year price momentum (smoothed residential transactions), solvency (Filosofi median income relative to the department) and local competitive saturation (SIRENE). Weights are recalibrated on the real transaction history — indicators to inform your decision, town by town.
