Public real estate intelligence

Compare investment zones with verifiable data

A few zones to compare

Loading the preview…

Five readings, one method

Cash flow

Compare a reference rent with an indicative purchase price without confusing gross yield with net cash flow.

Rising zones

Read annualized growth across complete years, with a sufficiently large sample.

Balance

Observe zones that are not dominated on either gross yield or growth, without a composite score.

Entry ticket

Relate a median price per square meter to a 50 m² reference property, without personalizing the budget.

Buy or rent

Compare the purchase price with the published reference rent as a duration indicator, not a recommendation.

What these figures say, and do not say

The data is aggregated at commune level. It describes neither an individual property nor an investor’s situation.

A zone may be absent when its history, sample, or published rent does not support a careful reading.

The displayed yield is gross and excludes notary fees, charges, vacancy, tax, and works.
