Read the three report elements and the 10 percent building-report threshold in context. ## TL;DR: Five checks before the work starts Put four things in one brief: the property as it stands, the work, the cost evidence and the intended result. In the listed NHG situation, a report can show current market value, the adjustments and market value after adjustment. A separate NHG building-report condition can use a 10% comparison between estimated immediate costs and market value. 1. Define the current property and the intended completed state. 2. List each work item, its cost evidence and any approval needed. 3. Ask the lender which report format, value points and building checks apply. 4. Commission the valuation with the work plan and documents attached. 5. Review assumptions, cost treatment and value after improvement before submission. If your Amsterdam decision also involves [mortgage valuation requirements in Amsterdam](/en/mortgage-valuation-amsterdam/), keep its lender requirements separate from the property question here. If you are also deciding on [purchase valuation in Amsterdam](/en/purchase-valuation-amsterdam/), keep that purchase purpose separate from the mortgage or valuation question here. ## Are you planning an Amsterdam renovation? If you are planning work on an Amsterdam property, you need to distinguish current value, planned costs and possible value after improvement. A clear brief helps the lender or other recipient understand the work and the evidence behind it. ## Before you start Have a written scope, drawings or specifications, a budget, the intended completion state and the report recipient. Note whether the work needs a permit, VvE approval or leasehold consent. Ask the lender whether it needs current value, value after improvement or both before you book an inspection. Use this renovation brief: “Address [ ], current state [ ], work items [ ], cost evidence [ ], approvals [ ], intended completed state [ ], current value/value after work [ ], recipient [ ], format [ ], valuation date [ ].” ## What a renovation valuation answers A renovation valuation connects a property at the valuation date with a defined work plan. It can describe the current market value, the adjustments and a market value after adjustment when the valuation purpose and applicable conditions require those elements. The [NHG rules for renovation valuation reports](https://nhg.nl/media/gtaickpv/vn-nhg-2026.pdf) set out that structure in the listed NHG context. The [NHG rule for reporting regular renovation costs](https://www.nhg.nl/faq/woning-waarde-verbetering/moet-een-reguliere-verbouwing-in-het-taxatierapport-zijn-opgenomen) says regular renovation costs should be visible in the report unless the pre-renovation value already supports the requested mortgage. This is a reporting and finance question. It is separate from the question of what a future buyer may pay for the finished work.

### Three figures, each with its scope **3 report elements:** current market value, the adjustments and market value after adjustment. They describe the valuation purpose's structure. They do not add up as three separate amounts. **10%:** In the listed NHG maintenance situations, a building report is needed when the average of estimated immediate costs is more than 10% of market value, or when further building research is needed. The comparison uses the stated NHG context. It does not predict the market response to an extension, kitchen or insulation package. Keep cost, current value, post-work value and building condition in separate columns. A lender outside the cited NHG situation may set different requirements. A sound [valuation report](/en/report/) keeps the property, purpose, valuation date and recipient visible, so you can test whether the conclusion fits your decision. When you compare quotes, relate the [valuation costs in Amsterdam](/en/costs/) to the scope, inspection, delivery conditions and follow-up you need. ## Requirements and constraints Prepare these fields before commissioning: - **Current property:** address, type, usable area, condition, legal context and known defects. - **Work plan:** item, quantity, specification, sequence and intended completion state. - **Cost evidence:** quotation, estimate, contingency, funding source and uncertain items. - **Approvals:** permit, VvE decision, leasehold consent and any building research. - **Report brief:** purpose, value points, format, recipient, validation and date. The [NHG requirements for a physical valuation](https://www.nhg.nl/faq/woningdefinitie/welke-eisen-stelt-nhg-aan-een-taxatierapport-van-een-fysieke-taxatie/) describe independence and accepted validation in the relevant physical-report context. Ask who prepares a building report, who validates the valuation and which document each person needs. ## Step-by-step: prepare the renovation records ### 1. Describe what exists Record the property type, floor area, construction period, leasehold, apartment structure, VvE position, maintenance and known defects. Use dated documents and mark any field that needs verification. ### 2. Describe the work Turn broad intentions into items: remove, repair, build, insulate, install or finish. Add drawings, specifications, contractor quotations and a schedule. State which parts are optional and which parts are required for the intended result. ### 3. Confirm approvals and finance conditions Ask the municipality, VvE, leasehold owner or lender which approvals apply. Ask the lender whether a physical or another report format is accepted and whether value after improvement must be shown. ### 4. Commission with one written brief Send the current property details, work plan, cost evidence, approvals, intended value point, report recipient and valuation date. Keep the accepted brief with the application. ### 5. Review the finished report Check the current value, listed adjustments, value after adjustment, cost assumptions, building-condition comments and report limitations. Ask about a mismatch before the document is used for finance. ## Scenarios and variations ### A high renovation budget Cost and market value measure different things. A €120,000 budget does not imply a €120,000 increase in market value. Ask which features, evidence and assumptions connect the work to the post-work figure. Keep contingency and optional upgrades visible. ### Immediate costs near the 10% mark Use the calculation named by the NHG rule: estimated average immediate costs divided by market value, multiplied by 100. If the result is close to 10%, ask which cost estimates and market-value figure the recipient will use, and whether further building research is needed. ### An apartment renovation Separate private work from work affecting shared elements. Add VvE minutes, approval, reserve-fund information, drawings and the deed of division. A private budget cannot grant permission for a shared structural change. ### A work plan changes after the inspection Record the old and new scope, cost difference, approval status and effect on the intended completed state. Ask whether the report needs an update or a new valuation brief. If you still have a question about the property, purpose or date, [contact Taxateur Amsterdam](/en/contact/) with the question and without personal attachments. ## Common mistakes and stalled preparations - Calling a budget a value increase: label cost and post-work value separately. - Sending a wish list without specifications: add measurable work items and drawings. - Leaving approvals until after the valuation: identify the municipality, VvE or leasehold question early. - Treating 10% as a universal building rule: state that the cited threshold belongs to listed NHG situations. - Omitting current defects: record them so the starting state is understood. - Changing the work after commissioning without telling the recipient: compare the old and new brief. If the preparation stalls, create a table with work item, evidence, approval, cost and unresolved question. Give each question to the person who can answer it and date the response. ## After the report: review and repeat Keep the report, work plan, quotations, approvals and lender instruction together. Revisit the application when the schedule, cost, property, report recipient or valuation date changes. A completed improvement may need new evidence if another decision uses the property later. ## FAQ ### Does renovation cost equal added property value? No. Cost records what is spent. Market value reflects the property, work, evidence, condition and market response at a stated date. ### What are the 3 report elements? In the listed NHG post-adjustment situation, they are current market value, the adjustments and market value after adjustment. ### When does the 10% building-report condition apply? The cited NHG condition concerns listed maintenance situations where the average estimated immediate costs exceed 10% of market value, or further building research is needed. Ask the lender whether it applies to your application. ### Can a valuation show value after renovation? It can when the valuation purpose and recipient require it and the work is described clearly enough to assess. Ask which report elements are needed before commissioning. ### What if the renovation has no final permit? Find out which approval is required and record the status. Tell the valuer and recipient rather than presenting the intended state as completed. ### Do I need a building report as well? A building report and valuation answer different questions. Ask the lender or other recipient which building evidence it needs and who should provide it.
