About Orange Fox.
Orange Fox helps English-speaking buyers understand a first Dutch mortgage estimate before they use it for a viewing, offer or adviser conversation.
The site is built for people who want the numbers to be clearer before they speak with a mortgage adviser, lender, buying agent or valuation professional.
Request a mortgage/adviser checkThe calculator is a starting point. The follow-up route helps turn the estimate into a clearer next question.
Why this site exists
A mortgage calculator can feel precise, but the first result is only a starting point. Dutch mortgage decisions can depend on income type, debts, student loans, lease obligations, property value, energy label, interest-rate period, lender policy and personal circumstances.
Use the calculator to see the monthly payment, buyer-cost gap and own-funds position before a viewing or offer conversation.
The page keeps the assumptions visible because a calculator can look more certain than it really is.
Use the result to prepare a practical mortgage/adviser check instead of treating the estimate as a lender decision.
The site can educate and route a lead. It does not give personal financial, tax, legal or bank advice.
Who is behind it
Dirk-Jan Bonenkamp is the primary expert behind the project. He is an Eindhoven-based certified appraiser, NRVT taxateur, NWWI taxateur and licensed valuer with residential property and valuation experience.
His role gives the site a practical property and valuation lens. The site should not be read as a bank calculation or personal mortgage advice.
Violetta contributes the English-first, expat-friendly and practical buyer perspective behind the project.

The first request should stay light: income range, target budget, timeline, buying alone or together, obligations, and the question you want checked. Do not send sensitive documents in the first request.
