Terms for your rent increase review

Have your rent increase reviewed. Scope and a fixed quote are agreed in advance.

Your rent increase review

LeaseCheckNL places the contract, chosen index and invoice beside the recalculated amount. We agree the properties, years, documents and delivery date in advance.

Fixed quote before work starts

You receive a fixed quote for the agreed assignment. Work starts after you approve the scope and price. A first email request does not take a payment or create an agreement automatically.

What the result means

A numerical difference is a reason to review the same contract clause, period and invoice items. It does not by itself prove overpayment, an incorrect invoice or a right to a refund.

Responsibilities and limits

You remain responsible for source selection, the applicable contract rules, CPI series, reference dates and further action. The result is not a legal, tax, financial or property judgment. Ask a qualified adviser if a clause or its legal effects are unclear.

Optional calculation example

The website example calculates locally in your browser. It does not upload a contract or review its meaning. The example is optional and is not required to request the service.

Data sharing and contact

Do not send contracts, invoices, personal data or confidential information with your first request. We agree a secure delivery route before sharing documents. Slimmezaken, operating under the Genantis name, Dutch Chamber of Commerce number 81946104, Amsterdam. alex@genantis.com.
