A construction deposit (bouwdepot) is a portion of your mortgage that is reserved specifically for renovation or improvement costs. Instead of receiving this amount directly, the funds are held in a separate account linked to your mortgage.
The money is released as you submit invoices or receipts for approved renovation costs. This allows you to finance renovation costs as part of your mortgage, rather than paying entirely from your own savings.
Construction deposits are commonly used when purchasing older properties that require upgrades or modernisation.
