Whether you want to sell, have inherited a property or simply seek clarity about your assets: the question What is my property worth? usually stands right at the beginning. The good news is that today there are several routes to an answer, from the quick online calculator through the free appraisal by an agent to the paid expert report. They differ markedly in accuracy, effort and cost. This guide shows you calmly and honestly which route suits which situation, which factors really determine the value and why a well-founded assessment protects you from costly mistakes. As an arm of Wolfgang Richter GmbH, we have accompanied owners for more than six decades in Düsseldorf and throughout NRW.
The three routes to a value assessment at a glance
There are essentially three routes to an answer to the question of what your property is worth. Each has its merit, but for very different situations.
- Online calculator: You enter some key data and receive a figure or value range within a few minutes. Quick and free, but only a rough first orientation.
- Free market appraisal (Markteinschätzung) by an agent: A locally knowledgeable professional looks at your property, takes condition and location into account and gives you a realistically achievable price. Close to the market and, for sellers, the most practical route.
- Paid expert report: A surveyor determines the value according to fixed rules. Time-consuming and expensive, but usable for authorities and courts.
Which route is the right one depends above all on your goal. If it is about a sale, you do not need an expensive surveyor. If it is about settling an inheritance or the tax office, an online figure is not enough. The next sections place the three routes in context for you.
Online calculator: fast, but only a rough orientation
Online valuation calculators are offered by portals, banks and agents. They process your details on location, size, year of construction and condition and compare them with data from similar properties. The result appears in seconds and usually costs nothing.
The appeal lies in the speed, the weakness in the accuracy. The providers themselves describe their results as a first orientation or guide value, not as a reliable market value. In practice, online estimates can deviate noticeably from the price later achieved depending on the property and data situation, and significantly so for unusual properties.
The reasons for this are understandable:
- No viewing: condition, modernisation status, floor plan, noise or brightness cannot be checked by any algorithm.
- Micro-location is generalised: neighbourhood, floor level, view or orientation barely feed in.
- Data quality: incorrect or embellished entries distort the result immediately.
- Special cases: period buildings, collector's properties or large plots are hard to press into a standard model.
As a rough ballpark, an online calculator is useful. You should not build a sales decision on it.
Free market appraisal by an agent
The personal market appraisal by an experienced agent is, for most owners, the most practical route and the one closest to the market. The decisive difference from the calculator: the property is actually viewed.
Typically it proceeds like this: in the preliminary talk the key data and documents are clarified. The agent then views the property on site, assesses condition, fittings, layout and micro-location and compares this with current offers and actual sales in the area. The result is a reasoned assessment of the realistically achievable price together with a recommendation on the pricing strategy.
Why is this free? A reputable market appraisal is for the agent the first step of a possible collaboration. If you seriously want to sell or let with support, the agent will gladly provide this assessment without obligation, because the work only pays off through a later successful sale.
Pay attention to quality: a good assessment is data-based and honest, not embellished. A deliberately too high price provides a good feeling in the short term but harms the sale. This is exactly where a locally knowledgeable provider specialising in Düsseldorf and NRW pays off.
Paid expert report: when it is worthwhile
An expert report by a qualified surveyor is the most thorough but also the most expensive route. It determines the market value (Verkehrswert) according to fixed, legally regulated procedures and is thus usable for authorities and courts.
One distinguishes two forms:
- Full report (Verkehrswertgutachten): comprehensive, with property description, location analysis and traceable calculations. As a guide, around 0.5 to 1.5 percent of the property value is often cited, so for a value of 500,000 euro about 2,500 to 5,000 euro.
- Short report (Kurzgutachten): more compact and cheaper, often in the range of about 700 to 1,000 euro, but legally usable only to a limited extent and intended more for your own orientation.
A full report makes sense or is even necessary when it matters legally: in cases of inheritance and gift vis-à-vis the tax office, in divorce and equalisation of accrued gains, before a court or in a dispute within a community of heirs. For a normal sale, by contrast, it is usually oversized. A well-founded market appraisal suffices here.
Which factors determine the value of your property
No matter which route you choose: behind every reputable assessment stand the same value-determining factors. Whoever knows them understands the result better and recognises unrealistic figures.
- Location: by far the most important factor. The macro-location (city, district, infrastructure) counts just as much as the micro-location (neighbourhood, noise, transport links, view).
- Size and living space: square metres, number of rooms and floor plan. For very large areas the price per square metre often drops somewhat.
- Condition and year of construction: modernisation status of roof, windows, heating and bathrooms. A maintenance backlog leads to noticeable deductions.
- Fittings: quality of floors, bathrooms and kitchen, plus balcony, garage, lift or accessibility.
- Energy efficiency: the energy certificate is mandatory when selling, and energetically good properties achieve higher prices, while weak energy classes are under pressure.
- Market situation: supply and demand as well as the interest rate level at the time of sale. The same value can be more or less achievable depending on the market phase.
We base our assessments on our own valuation system, which we secure with official sources such as the standard land values (Bodenrichtwerte) and data from the expert committees (Gutachterausschüsse) for Düsseldorf and NRW.
Market value, asking price and sale price: three terms, one difference
In conversation about property values, three terms are often confused. Separating them helps to classify every valuation correctly.
- Market value (Verkehrswert): the professionally determined, objective value. Legally it is defined in Section 194 of the Building Code (Baugesetzbuch) as the price that would be achievable in ordinary business dealings without unusual or personal circumstances. It is the neutral basis.
- Asking price: the price with which the property starts in the listing. It can strategically lie slightly above or below the market value but is no proof of the actual value.
- Sale price: the price on which buyer and seller finally agree and which is notarised. That is the only really hard figure.
In practice the sale price often lies below the asking price because negotiation takes place. In highly sought-after locations, however, it can also exceed it. The goal of good preparation is to keep asking price and market value close together, so that you give away no leeway and lose no interested parties.
Why a well-founded assessment decides between success and loss
The price is the most important lever in a sale, and both directions can become costly.
In the case of an overvaluation the property is set too high. It stays on the market for a long time, interested parties become suspicious, and after several price reductions less is often achieved in the end than with a realistic starting price. A property listed for too long quickly comes to be seen as burdened.
In the case of an undervaluation the property does sell quickly, but below value. Even a distance of a few percent from the market value can mean a loss in the five-figure range at today's prices. A low starting price also does not automatically lead to a bidding war that recovers the value.
This is precisely why the second step after the online calculator is worthwhile. A well-founded, locally knowledgeable assessment gives you a dependable basis for probably the most important financial decision of the coming years. No reputable party can give a guarantee for a particular price, but a realistic and well-reasoned assessment most certainly.
