Self-employed income can be used for a Dutch mortgage if a lender can establish a reliable income figure for the affordability assessment. This is known as the toetsinkomen, or assessment income, and is not the same as your turnover or the amount you invoice.
For a mortgage with the National Mortgage Guarantee (NHG), self-employed applicants who have been running a business for at least 12 months can have their income assessed through an Inkomensverklaring Ondernemer (Entrepreneur Income Statement). This assessment is carried out by an NHG-approved expert and does not automatically guarantee mortgage approval. Outside NHG, income assessment methods and acceptance criteria can differ between lenders.
Your business history, recent performance and financial records all help determine which income can ultimately be used.
