10 questions about residential property valuations in the Netherlands

TL;DR

Choose the kind of home valuation that fits your situation by starting with the purpose, property, value date and report recipient. A WOZ value, a market valuation and a mortgage report can concern the same address while serving different decisions.

Start with four fields: purpose, value date, evidence and recipient. Then confirm that the report is recent enough for its recipient and that the file contains the property facts supporting its conclusion.

Quick navigation

• Report type: market value, WOZ, mortgage or NHG report conditions.
• Dates: value date, property-condition date and the recipient’s deadline.
• Evidence: property records, comparable sales and independence.
• Next steps: report reuse, quote scope and safe document handling.

Before ordering a valuation report for the home purchase, ask your mortgage adviser which report your lender accepts and when it must arrive.

Once your offer is accepted, account for valuation timing in a home purchase when setting the inspection date and financing deadline.

If your lender asks for an NHG file, compare the NHG physical valuation report requirements with the recipient’s brief before you set the valuation date.

You may already have a report from an earlier purchase or refinance. Before paying for another, establish whether its date, purpose and report type still meet your lender’s requirements.

The Dutch government describes a general borrowing boundary of up to 100% of the home value, while income, debts, interest and other obligations still affect a mortgage decision. A valuation can inform the property-value part of that decision; it does not decide affordability.

What changes the valuation you need

Rijksoverheid and the Waarderingskamer set out the WOZ timing distinction. NHG sets dated conditions for mortgage reports, while NRVT material covers independence and investigation. National CBS figures add context for movement over time, not a value for one property.

When you brief a valuer, state whether you need a property valuation for a specific purpose, such as a purchase or refinance, and name the intended recipient and date. For a lender file, confirm its report type, NWWI review path and evidence requirements.

Keep five checks together: purpose, value date, evidence, recipient and report age. They help you compare fit; they do not rate a named valuer or replace the assignment terms.

10 questions to settle

1. What does a residential valuation actually answer?

A valuer forms an opinion about value for a stated purpose and date after considering the property and relevant evidence. The conclusion is meaningful because the file explains what was considered and what limits apply. A quick online indication can help with orientation, while a formal report answers a different need.

2. Is a WOZ value the same as market value?

Your WOZ value is set for municipal taxation and uses a value date one year before the tax year. If you are selling or refinancing now, you may need a market valuation for a later date. Compare the purpose and valuation date before treating two amounts as equivalent.

3. Which dates should I give the valuer?

Name the valuation date, the date of the property condition and the date by which the recipient needs the report. The Waarderingskamer distinguishes the value date from the state date, while market conditions keep moving between those moments. A report can be factually sound and still be a poor fit for a later decision.

4. How much can a valuation affect a mortgage?

The Dutch government states that borrowing for a home is generally limited to 100% of its value. Income, existing debts, the interest rate and other obligations still influence the amount a lender will accept. If the valuation comes in below your agreed price, discuss with your mortgage adviser how much of the gap you would need to cover with savings.

5. What is special about an NHG file?

The NHG 2026 conditions set a standard purchase-price or cost limit of €470,000 and a higher €498,200 limit when the energy-saving conditions are met. Those limits are separate from the report rules. In the physical-report context, NHG requires an independent valuer, accepted NWWI review and a report no older than six months from the valuation date.

6. Which property details belong in the file?

Give the valuer the address, property type, rights, floor area, condition, alterations, leasehold or ground-right details and relevant association records. The exact list depends on the property. Missing facts can limit what the valuer can assess and make a comparison with other homes less reliable.

7. How are comparable properties used?

Comparable sales are evidence, not a price menu. The valuer needs to explain why the homes are comparable and how differences in location, size, condition, rights, timing and quality affect the conclusion. NRVT disciplinary material stresses the value of own investigation and complete reference data. Distance alone is a weak selection rule.

8. When does independence matter?

Independence matters whenever another party relies on the conclusion. NRVT describes objectivity and independence as foundations of the valuer’s work. A requested outcome or a copied earlier report can weaken the reasoning. NWWI review may also matter when the named recipient requires an accepted NWWI review path.

9. Can I reuse an existing report?

Ask the intended recipient whether it accepts the report’s date and scope. A renovation, different lender or changed market evidence may require a new valuation even if the report is recent. The six-month NHG condition applies to that mortgage context; other recipients can set different requirements.

10. Can a valuation answer a personal tax or mortgage decision?

It can supply one piece of evidence. Tax treatment, borrowing capacity, affordability and contract choices belong with the relevant qualified professional. The report should state its purpose and limits so one value opinion is not mistaken for a wider recommendation.

Comparison cards: which answer do you need?

Orientation. You want a first sense of value before deciding whether to sell, buy or commission a formal report. A dated indication can help you decide what to do next, but a lender or buyer may not accept it.

Formal market-value assignment. You need a valuer to inspect the property, weigh relevant evidence and explain the conclusion for a stated date and purpose.

Mortgage or NHG file. You need the named recipient, report type, NWWI review path, report age and document list confirmed before the appointment. The lender still assesses income and debts separately.

Municipal WOZ assessment. You want to understand or challenge your tax valuation. Compare the municipality’s property details and reference sales with your home, using the dates and procedure that apply to the assessment.

What to include when requesting a valuation

Tell the valuer why you need the report, who will receive it and when it is due. Mention any renovation or ownership change since the previous valuation and send property records through the valuer’s secure channel. For a purchase, include the financing-condition deadline. Ask for the total fee and whether it includes inspection, report review, corrections, delivery, follow-up and VAT.

Common questions about the decision

Does a higher asking price prove a higher value?

No. An asking price expresses a seller’s position. The valuation conclusion depends on the property, date, evidence and purpose.

Does the 2026 CBS price index give my home’s value?

No. CBS reports that the national existing-home price index was 153.6 in 2026 Q1 on a 2020=100 basis, with a 5.2% year-on-year increase. That is national movement context, not a Rotterdam address-level conclusion.

Can I send every document through a public form?

Describe what you need to know before sending documents. Keep passports, contracts, bank details and other personal information out of the public form unless a qualified recipient gives you a secure channel.

When your plans change

If you first wanted an estimate before selling and now need a refinancing report, tell the valuer about that change. The property can remain identical while the report requirements change with its intended use.

What these checks can tell you

The mortgage and NHG figures describe dated rules, while the CBS index shows national price movement. Neither determines a Rotterdam home’s value, ranks firms, sets a fee or decides your mortgage or tax outcome. Confirm current report conditions with the intended recipient before commissioning work.
