Where our figures come from.

On a site about tenancy law every number has to be right. So here you find, for each amount and percentage, the source we use and the date it refers to. What we cannot take from a reliable source, we do not publish: a gap is better than a guess.

Rent limits

Source: the Dutch government, maximum rent limits as of 1 January 2026. The property value (WOZ) counts in full up to 186 points and for one third above that.

Maximum rent increase

The 2026 percentages come from the Dutch government, announced in December 2025: rent controlled a maximum of 4.1 percent from 1 July 2026, mid-rent 6.1 percent and free sector 4.4 percent, both from 1 January 2026.

Cost of a procedure

Source: the Rent Tribunal. A tenant pays 25 euros, refunded when they win. A landlord pays 500 euros, with a higher rate for repeated breaches.

Housing associations and landlords

Association names are checked against the official register of the Dutch housing association authority, which is decisive for spelling as well as for mergers and splits. Where we have a verified figure for the homes an association owns, we show it with its reference date and with the unit stated: a home is a home, while a rental unit also counts garages, storage rooms and commercial spaces. We never present a regional total as a municipal figure.

Commercial and institutional landlords are only named for a city when a local source confirms they own homes there.

Market figures

• Average property value: 439.000 euros. Source: Statistics Netherlands, published June 2026.
• Average free sector rent: 1.882 euros a month, and 20,94 euros per square metre. Source: Pararius Rent Monitor, second quarter 2026. These cover newly listed free sector homes only, not sitting tenants or social housing.
• Housing stock by ownership: 57 procent owner-occupied, 28 procent housing associations and 14 procent private rental. Source: Statistics Netherlands, 1 January 2024.

Our own figures

The win rates per case type come from our own analysis of published Rent Tribunal rulings in cases against private and commercial landlords. We publish them as rounded proportions, not as a prediction: every case stands on its own.
