For an expat mortgage in the Netherlands you generally need your passport or ID with BSN proof, your last three payslips, an employer statement, your employment contract, your most recent income tax return, a BKR credit overview and bank statements showing your own funds. If you are self-employed or benefit from the 30% ruling, a few extra documents come into play. Getting this paperwork right before you start looking at properties saves weeks of back and forth later.
Every mortgage file in the Netherlands, expat or not, starts with the same core set of documents. Lenders want to see who you are, what you earn, what you already owe, and how much you can put in yourself.
The base package typically includes a valid passport or ID together with proof of your BSN (burgerservicenummer, the Dutch citizen service number), your last three payslips or income specifications, and an employer statement confirming your role, salary and contract type. On top of that you will usually need your employment contract itself, especially important if you are on a temporary contract or still in a probation period, your most recent income tax return and assessment, a BKR overview listing all your existing loans and credit, and bank statements that show your available own funds, with any gifts or family loans clearly visible as separate transactions.
There is no requirement to hold Dutch citizenship or a permanent residence permit to qualify. Salary generally needs to be paid in euros, since most lenders will not accept income in a foreign currency, and your partner, if you are buying together, needs to reside in the Netherlands as well.
| Document | What it proves | Notes |
|---|---|---|
| Passport/ID + BSN proof | Identity and tax registration | Required for every applicant |
| Last 3 payslips | Current income level | Longer history often needed for variable income |
| Employer statement | Confirms role, salary, contract | Some lenders can use UWV data instead in pilot arrangements |
| BKR overview | Existing loans and credit obligations | Includes credit cards and buy-now-pay-later balances |
| Bank statements | Own funds available | Gifts or family loans need a visible, traceable transaction |
Beyond the standard file, expat applications add a layer of documentation around your right to live and work in the Netherlands. Lenders want this sorted early, not discovered halfway through underwriting.
This usually means proof of your residence permit, an expat-specific employer statement, and, if you are on a temporary contract, an intentieverklaring: a letter from your employer stating the intention to extend your contract or make your position permanent. Minimum residence requirements differ by lender, some accept as little as one month in the Netherlands, others want six months or more, so which lender you approach can genuinely change whether you qualify today or need to wait.
If you have credit history from your home country, some lenders will ask for evidence of it, since a clean Dutch credit file with no history can be treated cautiously by certain banks. None of this changes the borrowing rules themselves: expats can finance up to 100 percent of the purchase price, or 106 percent when energy-saving measures are included, on exactly the same terms as Dutch nationals. The extra documents exist to verify your situation, not to give you worse conditions.
If your salary includes the 30% ruling or expat allowances, expect a separate stack of paperwork just for that piece of your income.
You will typically need your 30% ruling decision letter from the Belastingdienst, plus documentation showing any structural allowances such as housing, relocation or international assignment allowances written into your employment contract or employer statement. Many lenders count these allowances toward your qualifying income, but only when they are documented as structural rather than one-off, and lenders differ noticeably in how generously they weigh them.
Worth knowing before you get your hopes up: most lenders calculate your borrowing capacity based on your full gross salary, as if the whole amount were taxable, so the 30% ruling mainly boosts your net income rather than the maximum amount you can borrow. Some lenders also stress-test what your affordability looks like once the ruling ends, so keep any documentation of your ruling’s start date and expiry within reach, it will come up in the conversation about your maximum mortgage.
If you work as a freelancer or run your own business, the document list grows, and a few of the standard expat shortcuts stop applying to you.
Self-employed applicants generally need three years of annual accounts, three years of tax returns and assessments, a profit forecast for the current year, and proof of registration with the Kamer van Koophandel (the Dutch chamber of commerce). Many lenders, especially for NHG-backed mortgages, also require an Inkomensverklaring Ondernemer, a certified income statement from an accredited bureau that costs roughly 250 euros excluding VAT for sole proprietors and around 445 euros for BV owners.
One point that catches people out: the 30% ruling only applies to an employment relationship, so if you operate as a self-employed sole proprietor (eenmanszaak), you cannot use the 30% ruling or the related tax-free reimbursement for extraterritorial costs, since both are payroll-based mechanisms. If you are a director-major shareholder (DGA) employed by your own BV, the ruling may still be available to you, provided you meet the standard conditions around recruitment from abroad, expertise and salary threshold.
Once every document is in and verified, the process moves faster than most people expect, but it still follows a fixed sequence rather than skipping steps.
The average mortgage application takes about four to six weeks from submission to final approval. Alongside your mortgage documents, you also need to plan for kosten koper (buyer’s costs), typically 3 to 6 percent of the purchase price, paid from your own funds rather than financed. This covers items like the valuation report, notary fees and advisory costs, several of which (valuation, notary fees for the mortgage deed, advisory fees) are tax-deductible, while transfer tax and estate agent fees are not.
After signing the preliminary purchase agreement, you will typically need to arrange a 10 percent deposit (waarborgsom), payable either from your own funds or via a bank guarantee. If you want a clearer picture of how your specific documents map to a realistic timeline, it helps to talk it through with an advisor rather than guess based on general rules; you can see the advisory team or get in touch directly through the contact page.
