Market Value, WOZ Value and Appraisal Value: Three Different Questions

TL;DR

Market value, WOZ value and appraisal value can all relate to the same Amsterdam home while answering different questions. Market value describes a market-based opinion under stated assumptions. WOZ value is the municipality’s tax assessment. Appraisal value is the conclusion in a commissioned report for a named purpose and date.

When you review a report, compare its purpose and date with the valuation report structure before you rely on the conclusion.

If you are separating market, municipal and appraisal values, compare your purpose and value date with market and WOZ value before treating the figures as interchangeable.

Start with the decision, not the number. A mortgage file, tax assessment, purchase discussion and estate division each need a different check. An asking price and a previous sale price add context, yet neither automatically answers the current appraisal question.

If the assignment requires a registered professional, keep the signatory’s NRVT registration beside the recipient’s requirements before you compare the report.

Keep the value questions separate

Ask the lender which report it accepts, who may prepare it, what acceptance review applies and how recent the value date must be. When a lender is involved, NHG report checks are one part of confirming report type, acceptance review and value-date requirements.

The conclusion comes after a defined property valuation process, including assignment, inspection and evidence review.

Why the same home can have several relevant values

Value is tied to a question, a date, an evidence set and a decision-maker. Change one of those and the meaning can change. This is why a public figure from a municipal register can sit beside a professional report without the two figures needing to match.

The most useful comparison uses five fields:

1. purpose;
2. value date;
3. method and evidence;
4. party responsible for the conclusion;
5. the decision you need to make.

Market value

Market value is a value concept used for an opinion about what a property could reasonably achieve in a market under the assumptions of the assignment. The opinion uses property facts, rights, market evidence and a stated date. Comparable sales can support the reasoning, with adjustments for differences in location, type, size, condition, finish and tenure.

Market value is a reasoned opinion. The eventual transaction can reflect urgency, negotiation, special conditions or information that differs from the appraisal file.

Use it when: the question concerns a market-based opinion for a purchase, sale, lending file or another named decision.

Check: what value date, assumptions and recipient does the assignment name?

WOZ value

WOZ value is the municipality’s assessment for property-tax purposes. The municipality applies its own assessment process and value date. The national government explains that the value date is 1 January of the previous year for the annual assessment. That time difference is one reason a current market discussion and a WOZ figure can diverge.

Use the municipality’s WOZ communication and the official WOZ channels when you need to check or challenge that assessment. A private appraisal can provide evidence for a different purpose, while the municipal procedure remains the place for a WOZ objection.

Use it when: you are dealing with a municipal assessment, property-tax bill or a WOZ objection.

Check: which assessment year and value date are on the notice?

Appraisal value

Appraisal value is the conclusion in a professional report for the agreed assignment. The report should identify the property, purpose, date, evidence, reasoning and limitations that support the conclusion. The recipient then decides whether the report meets its own file requirements.

The phrase can cover different assignments. A mortgage report may have lender or acceptance review conditions. An estate file may need a date tied to a legal or administrative event. A private report may support a decision between buyer and owner. Ask the appraiser to name the value concept and the intended use in the brief.

Use it when: a named recipient needs a documented opinion for a defined decision.

Check: is the report current for the recipient’s rule, and is the stated purpose the one you need?

The five-field decision framework

Write the question in this format:

I need [type of value] for [decision], for [recipient], at [date], and I have [records].

Then test the answer:

• If the municipality is responsible, start with the WOZ notice and municipal procedure.
• If a lender or reviewer is responsible for acceptance, ask for its current report conditions.
• If you need a professional opinion about the property for a private decision, define the assignment with the appraiser.
• If the question concerns defects, commission a building survey alongside any value question.

This framework prevents the common mistake of using the most visible number as the right number.

Three Amsterdam situations

Buying an apartment

The asking price expresses the seller’s position. A commissioned appraisal can test the property, rights, market evidence and purpose at a stated date. An apartment file may also include VvE information, the division deed and planned works.

Reviewing a WOZ notice

Start with the assessment year, value date, property description and municipal evidence. A private report can explain a market question, yet the objection belongs in the municipal channel.

Figures that sit nearby

An asking price is a marketing position. A transaction price is a recorded result with its own conditions. A WOZ value is a municipal assessment. A market value opinion is a professional analysis under an assignment. An insurance rebuild figure answers a different question about rebuilding cost. These numbers can inform a conversation without becoming interchangeable.

Questions you may have

Should market value equal the WOZ value? There is no reason to expect a match because purpose, date and method differ.

Can an asking price prove market value? It shows what the seller wants to achieve. Comparable evidence and analysis for the named assignment are still needed for a market opinion.

Can a private appraisal change a WOZ assessment? The municipality controls the WOZ process. Use the evidence and procedure required for the municipal question.
