Value Before and After Renovation Taxatie
Value Before and After Renovation Taxatie for Dutch homes. Prepare condition, energy, renovation, and document details before your residential valuation.
Condition factors explained
Taxatie is the Dutch word used for a property valuation or home appraisal. In a mortgage setting, it usually means a formal residential report prepared for a stated purpose.
Condition and renovation details should be shared before inspection, because they affect what the appraiser needs to review and how the report explains the property.
Condition and document checks
Condition details can change the questions an appraiser has to answer. Prepare known defects, renovation plans, energy label information, maintenance records, inspection reports, and any available foundation information.
For renovation financing, the value assessment needs more than a general idea. Quotes, specifications, drawings, and a clear work list help the appraiser understand what will change and which value question has to be answered.
Energy upgrades can be helpful, but they should be documented. Solar panels, insulation, heat pumps, and energy labels are easier to assess when ownership, age, invoices, and technical details are available.
Condition evidence
Prepare known defects, maintenance notes, inspection reports, energy label data, and renovation plans before the appointment.
Renovation detail
For renovation financing, send quotes, drawings, specifications, and the intended work list before the value assessment.
Foundation context
The 2026 model report gives foundation risk more attention, so available foundation information should be gathered early.
Energy upgrades
Solar panels, insulation, heat pumps, and energy labels are useful only when the details are clear and documented.

Prepare the file before inspection
A better first check starts with the documents and wording already in your inbox. Use this list before you request a callback.
Save the exact wording
Keep the message from your mortgage advisor, lender, notary, or broker. The small words around NWWI, NHG, validation, deadline, or report type can matter.
Gather property evidence
Collect the purchase agreement, property address, energy label, renovation notes, apartment or VvE details, and any inspection or condition information.
Check timing early
The usual report turnaround is 5 working days after intake. Urgent handling can be 3 working days or less where feasible and costs EUR 60 incl. VAT.
Ask before you assume
Commercial properties and new-build valuations are outside the current scope. If your case is unusual, ask your advisor what evidence is accepted before you book.
How condition details are reviewed
Condition and energy details help the appraiser understand the home before and during inspection. The details matter more when the property is older, renovated, or partly unfinished.
Known defects
Share known defects, repairs, maintenance notes, inspection findings, and foundation information early. Surprises during inspection can slow the report.
Energy details
Energy label, insulation, solar panels, heat pump information, invoices, and ownership details help explain upgrades without guessing.
Renovation evidence
Quotes, drawings, specifications, permits where relevant, and a clear work list help separate current condition from planned work.
Apartment condition
For apartments, VvE health, maintenance planning, reserve level, common areas, and service costs can matter alongside the private apartment condition.

What to send in the first message
A condition-sensitive request should be honest about what is known and unknown. Known defects, repairs, energy upgrades, renovation plans, and inspection findings are useful when they are shared early.
Property and purpose
Share the address, property type, and reason for the valuation. Mention whether the file is for a purchase, refinance, renovation financing, sale decision, personal matter, or another residential property question.
Deadline and recipient
State who needs the report and by when. If a lender, mortgage advisor, broker, notary, legal advisor, or tax advisor is involved, say which person or organization will use the value.
Original wording
Copy the exact Dutch or English wording you received. Keep terms such as NWWI, NHG, NRVT, taxatierapport, validation, WOZ, market value, and inspection visible instead of rewriting them loosely.
Available files
List what you already have: purchase agreement, ownership information, energy label, VvE documents, renovation plans, inspection notes, photos, or any lender checklist. Missing files can be added after intake.
Questions before you request a valuation
Do renovations always increase value?
No fixed uplift can be promised. The valuation considers the work, evidence, market response, property condition, and purpose of the report.
What condition documents help?
Inspection reports, repair notes, renovation quotes, energy label details, VvE files, and known defect information can all help the appraiser assess the home.
Does foundation risk matter in 2026?
Yes. The renewed 2026 residential model report gives foundation information more attention, so available foundation documents should be shared early.
