Property Valuation
Online Value Analysis
quick online appraisals
Need to know the value of a property, but can't wait weeks for an appraisal? A data-driven online valuation provides a reliable value assessment in just a few minutes. This allows you to make informed decisions without costly delays.
With access to Google, BORIS, and Deep Research.
Quick online assessments use AI and official data (e.g., from appraisal committees) to deliver a reliable property valuation in minutes.
The accuracy is high: Modern systems analyse millions of data points and often achieve a deviation of only 5-10% from the actual sale price.
For heirs, sellers, and investors, an online appraisal is the ideal first step to quickly obtain a well-founded, cost-efficient basis for decision-making.
Are you facing an inheritance, a sale, or an investment decision and urgently need a realistic property valuation? The traditional route via a comprehensive appraisal often takes weeks and incurs costs of up to 1.5% of the property value. Modern, fast online appraisals offer an efficient alternative. They combine artificial intelligence with official market data to provide you with an accurate valuation within minutes. This article shows you how this technology works, what data it is based on, and how you can use it to create a solid foundation for your financial decisions.
In a dynamic market, time is a critical factor. Property prices in Germany increased by approximately 94% between 2010 and 2022. Those who wait for a traditional appraisal often lose valuable weeks, during which market conditions can already change. A manual appraisal can easily take 14 to 21 days. This delay can be the difference between a good and an excellent price when selling. A quick online appraisal provides an initial, well-founded value assessment in under 5 minutes. This speed enables owners and heirs to take immediate action. The digital method is not only faster but also often the first step to a comprehensive online value analysis. The efficiency of digital processes is therefore key to making the right decision at the right moment.
Modern online evaluations use Automated Valuation Models (AVMs) based on artificial intelligence. These systems analyze vast amounts of data to estimate the value of a property, minimizing human error. An AVM processes not only basic data such as year of construction and living area but also unstructured information like property photos or textual descriptions. AI identifies patterns and connections that remain hidden to humans, thereby enhancing accuracy. For example, analyzing over 2 million listings can reveal price trends for specific features. This technology does not make an evaluation by qualified appraisers obsolete, but rather more efficient. It provides a data-driven preliminary assessment that serves as a solid foundation for further steps.
The accuracy of an online appraisal hinges on the quality of the underlying data. Reliable systems use the same sources that experts rely on. This primarily includes the purchase price collections from official appraisal committees. These bodies receive a copy of the purchase contract from every notary, ensuring comprehensive market data collection. Another crucial factor is the land value, which indicates the average locational value of a property. Through the nationwide portal BORIS-D, these values, updated at least every two years, are accessible to everyone. A good online appraisal integrates these official data and combines them with current offer data from over 100 different platforms. This creates a comprehensive picture that significantly strengthens the reliability of online evaluations. The following list shows the most important data sources:
Purchase price collections: Collections of all real transactions maintained by appraisal committees.
Land values: Officially determined property values, available through portals like BORIS-D.
Location data: Analysis of micro and macro location, including infrastructure and demographics.
Building data: Year of construction, size, condition, and energy performance indicators from official documents.
Comparison objects: Current offer prices of similar properties from over 100 online sources.
This variety of data forms the basis for a precise and quick evaluation.
The most common question is about reliability. A purely online tool without an in-person appointment cannot replace a legally binding market value appraisal. Its strength lies in providing a quick, data-driven market price estimation. Studies show that AI-supported systems can even surpass the accuracy of traditional methods, as they consider more data points. The deviation with high-quality AVMs is often only 5-10% from the final sale price. For an initial orientation, such as when considering a sale or assessing an inheritance share, this precision is more than sufficient. For more complex cases like a divorce or submission to the tax office, a live evaluation via video or a short expert opinion is the next logical step. The online evaluation serves here as a cost-efficient preparation.
A quick online assessment is the ideal tool in many situations. It provides a sound basis for decision-making when speed is essential and the costs of a full appraisal (up to €6,000 for a value of €400,000) should be avoided. Here are typical scenarios:
Intention to Sell: You receive a realistic price range and can plan your sales strategy based on market data, rather than relying on gut feeling.
Inheritance: Co-heirs quickly receive a neutral and objective valuation of the property, which can avoid disputes. An initial assessment is available within minutes.
Asset Overview: Owners can determine the current value of their property for regular review of their financial status, which is sensible with a price increase of 94% over 12 years.
Purchase Interest: Prospective buyers can quickly assess an offer and check whether the asking price corresponds to the market value.
For these cases, the efficiency of online platforms is a clear advantage. They create transparency before high costs arise.
A quick online appraisal is more than just a rough estimate. It is an intelligent tool based on the analysis of millions of market data points and official sources. The technology allows heirs, owners, and investors to obtain a valid valuation in minutes, where previously weeks of waiting were necessary. The biggest advantage lies in the combination of speed, data foundation, and cost efficiency. You receive an objective basis to minimise risks and make informed decisions. If you are facing an important property decision, take advantage of the option for a digital initial assessment. With tools like the ImmoGPT chat or a free initial assessment from Auctoa, you immediately get the clarity you need for the next steps.

Yes, your data is treated with strict confidentiality and processed in accordance with the General Data Protection Regulation (GDPR). The assessment is solely for your information and will not be shared with third parties without your consent.
Can I sell my property with an online appraisal?
Yes, the online appraisal is the perfect starting point for a sale. It provides you with a realistic price indication and a data-based basis for negotiation. For the final offer price, we recommend discussing the results with an expert.
What is the difference to a broker appraisal?
An online appraisal from Auctoa is a neutral, data-driven analysis without sales interest. A broker often evaluates a property also with a view to a potential sales mandate. Our assessment serves as an objective digital compass for your decision.
What do I do if my property is very specialised?
For unique or very complex properties, purely automated assessments reach their limits. In such cases, we recommend a hybrid solution like our live video appraisal, where an expert digitally records the specifics of your property and incorporates them into the assessment.
