Questions and answers

What can AI do for a property appraiser?

Datawonder uses AI for the writing and looking up around an appraisal: writing up inspection notes into report text, gathering property data and sources in one file and automating scheduling and reporting back to clients. The appraiser reviews the draft and determines the value. AI does not take over that judgement.

Can AI write up my appraisal report?

AI can produce a first draft of the sections that come back in every report, based on your inspection, your notes and the property data. You read that draft, correct what is wrong and sign. Datawonder builds it so that you see which source a passage comes from, so you can check quickly.

Is there software that supports land valuations?

Yes. As its own work, Datawonder has built a land valuation application that brings property data and sources together and produces a draft the appraiser only has to review. The application was not commissioned. It shows what is possible and is a starting point if you need something similar.

Can AI gather property data and sources for an appraisal?

Yes, from the sources you now consult by hand, as far as they can be retrieved digitally. Datawonder brings that data together in one file per property, so you do not have to search separate systems. Which sources can be connected depends on what they offer: with a properly documented API it is almost always possible.

Does AI determine the value of a property?

No. In the software Datawonder builds for appraisers, the appraiser determines the value. AI gathers data, writes up texts and prepares the file. The valuation and the responsibility for it stay with the appraiser.

Can scheduling with clients be automated?

Yes. Datawonder can automate scheduling inspections and reporting back to clients, so confirmations, reminders and status updates go out by themselves. A voice agent can also put appointments in your calendar by phone. You keep time for the work on site and for the judgement.

What about privacy in appraisal files?

Appraisal files often contain personal data of owners and clients, so the GDPR applies. Datawonder records up front which data the system may see, where it is processed, how long it is kept and which data processing agreements are needed. Where possible, personal data stays out of the AI.

How do I get started with AI in my appraisal practice?

With the part that comes back in every file and takes the most time. In a free thirty-minute intro call Datawonder looks at where that is. After that you get a quote with a fixed price, per phase or for the whole project, so you can start small and only expand once it works.

What does the Landwaarde demo show?

It shows fictional cases for market value, compensation, Dutch WOZ valuations, financing and financial reporting. The application connects property details, evidence, calculation models, checks and reporting. It is Datawonder’s own work, not a client commission.

Does Landwaarde determine the valuation automatically?

No. Calculation models support the reasoning and show results based on the assumptions entered. The appraiser assesses sources, explains the judgement and determines the final value.

Are the screenshots real client files?

No. All people, locations, amounts and evidence shown belong to fictional demonstration files. The screenshots were captured directly in the working application.

Can I use this demo for real files straight away?

The demo shown stores data locally in the browser. Before use with real files, we agree on configuration, access, security, storage and backups. The screenshots do not promise an immediately available hosted subscription.

How do I start improving my valuation workflow?

In a free 30-minute call, we discuss one recurring step in your workflow, the information it requires and the judgement that stays with you. You can then choose a fixed-price proposal, per phase or for the entire project.
