Buyers, homeowners, lenders and advisers can use this checklist to spot the mistakes that lead to the wrong report, a late delivery or an avoidable extra charge. ## TL;DR Most selection mistakes begin before the appointment: the purpose is vague, the recipient is unknown, the property facts are incomplete or the quote leaves work unstated. Fix those points first, then compare people, price, timing and acceptance. For an NHG physical valuation, NHG currently requires an independent maker, validation by an accepted validation institute and a report that is no more than six months old from the value date. That example shows why the right appraiser depends on the report's use. Other lenders and recipients can apply different conditions.

Once you name the decision, the rest of the valuation becomes easier to follow. One selection mistake is treating a local price signal as universal. If you are comparing a property near Eindhoven, test the actual property and purpose against [residential evidence from Eersel](https://taxatieeindhoven.com/property-valuation-eersel/) rather than treating one local figure as decisive. ## Why the order of checks matters A quote is an offer for a defined task. If the task is vague, two prices can cover different inspections, searches, report types, validation steps or delivery dates. Comparing the amounts first creates a false sense of precision. Use this order: 1. **Purpose:** why is the value needed and who will use it? 2. **Acceptance:** which registration, method, model and validation conditions apply? 3. **Scope:** what work, evidence and output does each quote include? 4. **Timing:** when will inspection, draft, validation and final delivery happen? Matching each provider's scope is the third check, and [valuation quote comparison](/en/guides/how-to-compare-property-valuation-quotes/) keeps that comparison reliable. The errors below are the ones that make it unreliable. Now bring the property facts and the planned decision into one brief. ## Prepare the brief before contacting providers Have these facts ready: - the property address and type; - the reason for the valuation; - the report recipient and any written requirements; - the intended value date or transaction date; - known leasehold, apartment, renovation or special-property details; - the required delivery date; and - documents already available, such as plans, permits, invoices or an earlier report. This is a starting file, not a promise that every document is needed. [Property valuation documents](/en/guides/property-valuation-document-checklist/) help separate available evidence from information the provider still has to obtain. ## Mistake 1: choosing from the price before defining the purpose The same word, “valuation”, can describe different work. A lender may need a report with a named model and validation. A seller may first want a price discussion. A court or tax authority may need a valuation for a different date and question. **Prevention:** write one sentence that begins, “The report will be used by…” and name the decision. Ask every provider to confirm that use in the quote. ## Mistake 2: assuming every report is accepted everywhere Professional status and report acceptance answer different questions. An appraiser can be suitable for one purpose while a lender requires a particular validation method or a current report model. **Prevention:** ask the recipient or adviser for the current written requirements before selecting a provider. The NHG example shows why [NHG valuation requirements](/en/guides/nhg-property-valuation-requirements/) must not be turned into a universal lender rule. ## Mistake 3: skipping the independence check NRVT guidance describes threats such as prior involvement with the property, personal or business ties, financial dependence and pressure to reach a chosen value. A provider should be able to explain how a possible threat is assessed and recorded. **Prevention:** ask whether the provider or firm has advised, brokered, inspected, managed or valued the property before, and whether there is a connection with another party. Prior involvement makes [appraiser independence and conflicts of interest](/en/guides/appraiser-independence-and-conflicts-of-interest/) a necessary question set. ## Mistake 4: comparing prices for different scopes One quote may include inspection, research, report writing and validation. Another may exclude a site visit, special research or the validation charge. The lower amount then represents a different task. **Prevention:** put the scope into a short comparison block. Record the method, inspection, evidence sources, report type, validation, fee inclusions and delivery point for each quote. Mark unknown items as questions rather than treating them as included. ## Mistake 5: ignoring the report date and delivery chain A final report date can hide earlier steps. Inspection, draft review, validation and lender submission each consume time. A report that arrives after a decision deadline may require rework even when the valuation itself is sound. The NHG six-month condition is a useful example of date sensitivity. NHG measures age from the value date in the stated physical-report context. It does not mean that every report can be reused for every recipient for six months. **Prevention:** ask for dates for inspection, draft, validation and final delivery, then confirm the date window with the recipient. Appraiser selection under a tight deadline turns the target date into separate checkpoints. ## Mistake 6: confusing an online estimate with a formal report An online estimate can provide an early sense of market direction. A formal report answers a defined valuation question with a stated method, evidence and recipient. Kadaster likewise separates information products that help estimate a home's value from a current valuation by a professional. **Prevention:** ask what the output is called, who may rely on it and whether the recipient accepts that method. The distinction between online and physical valuation matters before a quick result is treated as a report substitute. ## Mistake 7: sending an incomplete brief Missing plans, permits, leasehold details or renovation evidence can create follow-up questions and delay the report. It can also make a completed improvement look like a future plan or leave an assumption unresolved. **Prevention:** send the available file with clear dates and label known gaps. Do not create or alter evidence to make the property fit a target value. Ask which missing item affects the scope or timing. ## Mistake 8: treating ratings as proof of assignment fit Reviews can help you ask about communication and process. They cannot verify independence for your transaction or acceptance by your lender. Appraiser reviews and ratings are most useful when four signals are weighed instead of turning the star average into a ranking. **Prevention:** use review evidence to form questions, then obtain the answers in the quote or call. ## Three scenarios ### A mortgage report after an accepted offer The first question is the lender's acceptance method. Confirm the required report type, validation and freshness before comparing fees. The date of inspection and value date belong in the brief. ### A seller deciding on an asking price The first question may be transaction advice rather than a lender report. A broker's price indication and an independent valuation have different roles. Ask which output you are paying for and who needs to rely on it. ### A home with planned renovation Separate current condition from proposed work. Ask whether the report needs a value after improvement and which plans, budgets or specifications support that scenario. Do not compare it with a quote for current market value alone. ## Aftercare: confirm the choice in writing Before accepting, keep a one-page record of: - purpose and recipient; - appraiser and required registration; - independence answer and disclosed safeguards; - method and report type; - included work, validation and fees; - inspection, draft and final dates; and - documents still outstanding. Read the quote after the call. If a verbal promise is absent from the written scope, ask for correction before paying or scheduling. ## Troubleshooting a bad fit ### The cheapest quote is missing information Ask whether the missing item is outside scope or simply unstated. Compare the revised answer with the other quotes only after the scope matches. ### The provider cannot name the recipient requirements Pause the order and obtain the requirements from the lender, adviser or other recipient. A general statement that “all reports are accepted” is too broad to settle the question. ### The deadline has moved forward Ask which checkpoint can move, whether validation is included in the new date and what happens if the report misses the recipient's cutoff. The answer belongs in writing. ### The property has a special feature Describe the feature early: leasehold, monument status, split ownership, ongoing construction, rental use or a complex apartment structure can change the evidence and experience needed. Use these questions to test whether the proposed work fits your situation. ## FAQ ### Is the cheapest property appraiser the best choice? Price matters after purpose, acceptance, scope and timing match. A lower quote for a different output is not a useful price comparison. ### Does a registered appraiser guarantee lender acceptance? No. Registration and lender acceptance are related checks with different scopes. Confirm the report and validation conditions with the recipient. ### Is an online valuation always a mistake? No. It can be useful for an early estimate when the recipient accepts it for the intended decision. Confirm the output and acceptance before relying on it. ### What should I do when a report is late? Ask for a written status, the remaining steps and the new final date. Check with the recipient whether the report can still be used and whether a new value date or report is needed.
