chathome.lu Price Index — July 2026

What does the July 2026 index show?

The July index puts the unweighted median of 20 publishable commune apartment medians at 8 418 €/m².[^1] Luxembourg City has the highest observed median at 11 670 €/m², supported by n = 802 sale listings. Dudelange has the lowest at 5 380 €/m², supported by n = 87.

Among communes with publishable sale and rent medians, Pétange has the highest indicative gross yield in this snapshot at 6,4 %. Its sale median is 6 766 €/m² from n = 72 listings; the rent side uses n = 7 listings.[^1] Gross yield is a simplified ratio of annualised median asking rent to median asking sale price, before vacancy, financing, maintenance and tax.

Why can commune medians differ?

The index measures the active stock offered in each commune, so its composition matters. A commune median can differ because the mix of apartment sizes, conditions, energy performance and micro-locations differs; a change in that mix can also move a later monthly median even when like-for-like homes have not changed price. The dataset therefore describes the observed asking-price distribution but does not assign a causal effect to any one local factor.

The gap between Luxembourg City and Dudelange is 6 290 €/m² in this snapshot.[^1] That figure is a comparison of commune medians, not the expected discount on a particular apartment. Buyers should compare the relevant segment sample and the underlying property characteristics before applying a commune benchmark to one home.

Which communes are directly comparable?

The table below keeps the segment sample next to each median. It is a focused cross-section, while the full Luxembourg Price Index contains every currently covered commune and links to commune-level evidence.

How is the index calculated?

The published Price Index method uses active, catalog-visible residential listings only. For each commune, offer type and property type, ChatHome divides the asking price by usable floor area, removes implausible residential values and publishes a precise median only at n ≥ 5. This issue was computed 2026-07-06; the national headline is the unweighted median of the 20 publishable commune apartment-sale medians.[^1]

What are the limits of this snapshot?

Asking prices are seller expectations, not completed transaction prices, and the index does not value a specific property. Coverage reflects active listings ChatHome could verify on the computation date. The first month establishes a baseline, so month-over-month movement begins with the next issue; a real methodology change will receive a new version rather than a cosmetic date update.
