Homeowners, lenders and advisers can match the work, evidence and report date to a construction loan or another decision. ## Table of contents - [TL;DR](#tldr) - [What this valuation needs to answer](#what-this-valuation-needs-to-answer) - [Why current and future value must be separated](#why-current-and-future-value-must-be-separated) - [Facts behind renovation finance](#facts-behind-renovation-finance) - [A renovation valuation path](#a-renovation-valuation-path) - [Common mistakes and edge cases](#common-mistakes-and-edge-cases) - [FAQ](#faq) ## TL;DR Use a current-value report when the lender needs the home as it stands and a post-work value when the brief calls for the finished scenario. Plans, permissions, budget, condition and market evidence must support the scenario; renovation cost alone does not set the new value. Separate three facts: the current condition, the planned work and the value after work. A budget shows intended expenditure. It does not prove that every euro of cost creates the same amount of market value. Plans, permits, specifications, timing and condition evidence let the appraiser explain the assumptions. NHG's current guidance is a useful example of why method matters. It says named hybrid valuations do not include quality improvements in the value determination, while other energy-saving routes can require a physical valuation and a renovation specification. The rules depend on the product and lender, so treat the example as a prompt for questions rather than a universal answer.

Once you name the decision, the rest of the valuation becomes easier to follow. For a renovation loan near Eindhoven, compare [existing residential evidence from Oirschot](https://taxatieeindhoven.com/property-valuation-oirschot/) with the planned works before you include any assumptions in the brief. ## What this valuation needs to answer A property valuation reports an opinion for a defined purpose and value date. In a renovation file, the purpose can be to support an additional loan, a construction loan, a building deposit or an energy improvement. The assignment may need one value, two values or a value with stated assumptions about completion. The appraiser does not approve the loan, certify that a contractor will finish or guarantee the final market response. The lender decides whether the report and the proposed work fit its credit policy. [Mortgage valuation report requirements](/en/guides/when-is-a-valuation-report-needed-for-a-mortgage/) connect the report to that lender question. Here is why the distinction matters when you are arranging the report. ## Why current and future value must be separated Current value describes the home as it exists on the relevant date. Value after work is a scenario that depends on the work being completed to the stated specification and on the market conditions used in the valuation. A report should make that distinction visible. Cost and value are related evidence, but they are not the same measure. An extension may add useful floor area, while specialist work, poor layout, permissions, quality, timing or local buyer demand can affect how the market responds. Ask what assumptions the conclusion uses. The value date matters twice: it anchors the current opinion, and it can anchor the post-work scenario. If the lender's rule is based on a later completion date, ask how the report handles that timing. Do not assume a report written before work remains current after the work is complete. ## Facts behind renovation finance ### Current condition Record the home's existing layout, size, finish, maintenance and defects. Photographs, plans and an inspection can help. The starting condition is part of the valuation evidence. ### Work specification Describe the work in a way another party can understand: scope, materials, floor area, energy measures, contractor or self-build approach, permissions and expected completion. “Modernise the house” is not a usable specification. ### Budget and direct costs List the budget by work package and identify what is included. A lender may request invoices, a building report or a cost schedule. Costs can be revised, so date the budget and retain the assumptions. ### Value after work This is a reported scenario, not a promise. It depends on the completed work, evidence, assumptions and market conditions. Ask whether the lender needs this scenario and how it will be tested. ### Physical and hybrid methods The lender or scheme can decide whether the case can use a physical inspection, a hybrid method or another method. NHG's guidance shows that a hybrid method does not answer every improvement question. ### Building deposit A building deposit is a financing mechanism with conditions set by the lender. Ask how money is released, what invoices or checks are needed, and what happens to a remaining balance. ## Questions that belong with this decision NHG valuation requirements apply where NHG is involved. Energy-label valuation matters when energy evidence changes the assignment, without turning a label into a guaranteed price effect. The evidence file needs property valuation documents, and property valuation cost factors tie quote differences to actual work. If the work is part of a refinancing, refinancing valuation sets the narrower purpose. ## A renovation valuation path ### 1. Ask the lender for its case definition Confirm whether the request is a renovation loan, construction loan, energy budget, mortgage increase or another product. Ask which value, method, report model, inspection, documents and validation method are required. ### 2. Write the current-state brief Record the property identity, current layout, floor area evidence, condition, defects, leasehold or homeowners' association limits and any work already started. Include the value date the lender specifies. ### 3. Detail the planned work Attach drawings, specifications, permissions, quotes, budgets and a realistic timeline. Separate work that changes the home from loose contents, maintenance or work that the lender does not finance. ### 4. Choose a provider for the accepted method Ask what the provider will inspect, whether the report includes a future-value scenario, which assumptions it records, who signs it and how corrections are handled. Confirm acceptance with the lender before the appointment. ### 5. Review the report and the depot conditions Check current value, value after work where requested, costs, assumptions, value date, report recipient and any direct-cost or building-deposit notes. Ask the lender how invoices, inspections and remaining funds will be handled. Keep these points in view when you ask for the report. Before you book, check the mistakes that can create extra work or leave you with the wrong report. ## Common mistakes and edge cases ### Treating the budget as added value A €50,000 budget is evidence of planned expenditure, not proof of a €50,000 increase in market value. Keep the two figures labelled separately. ### Starting work before the report brief is clear Work already underway can change the evidence and the lender's process. Ask what must be documented before demolition or construction starts. ### Using a hybrid valuation for every improvement The method may not include the planned quality improvements. Ask the lender and read the named scheme conditions. ### Ignoring permissions or homeowners' association rules An extension, split, structural change or façade alteration may depend on permits, leasehold terms or association decisions. Share those constraints. ### Leaving self-build work undocumented Record who does the work, which costs are purchased, what specification applies and how completion will be evidenced. Lenders can require their own checks. If cost, timing or acceptance still concern you, ask the provider to state each condition before the appointment. ## FAQ ### Does a renovation loan always require a valuation? No universal answer applies. The lender can require a valuation, building report, cost specification or another form of evidence. Ask for its current case definition. ### Does the appraiser value the finished home? The assignment may include a value-after-work scenario. That scenario depends on the stated work and assumptions. A completed home calls for a different inspection question. ### Can a hybrid valuation include renovation value? It depends on the scheme and case. NHG states that quality improvements are not included in the value determination for its named hybrid method. Confirm the current lender rule. ### What documents should I prepare? Prepare plans, specifications, permits, budgets, quotes, current-condition evidence, energy information and homeowners' association or leasehold documents where relevant. The lender or appraiser may request more. ### What happens if the work costs more than planned? Ask the lender before spending beyond the approved scope. A cost overrun can affect the building deposit, loan structure, completion evidence and the value scenario.
