Could an AI agent really appraise my flat over the phone? I called Nextimmo’s new voice-powered valuation tool to find out.
I recently got a valuation on my apartment from a woman called Victoria. I’m not planning on selling any time soon, but I was curious to test Nextimmo‘s new remote property valuation service, powered by artificial voice intelligence.
The press release sounded promising: no more cumbersome forms—just a five-minute call with an AI agent.
The call didn’t get off to the best start. When I gave my address, Victoria—the AI agent—misheard and began referencing Thionville. As a Brit, I don’t like to interrupt, even with an AI. But in this case, I had to. Once back on track, I briefed Victoria on the size of my flat, the construction year, its condition, and added features such as a balcony and parking.
“Our aim is to make life easier for sellers while providing them with high-performance, accessible and intelligent tools,”
Rudolphe Aben, Nextimmo managing director
The conversation flowed smoothly in French until, without warning, Victoria switched to English. The shift may have been triggered by my accent—perhaps an implicit sign that the AI struggled to interpret my French.
After a few further misunderstandings, Victoria delivered a valuation range. I’ve never sought a valuation of my home before and don’t plan to. But given the current market and high interest rates, the estimate sounded ambitious. Still, since I’m not planning to sell, who’s to say? Perhaps it’s spot on.
Nextimmo, which was launched in 2022 by a team of co-founders from Immotop, released the phone valuation platform in mid-July. Callers can opt for a five-minute simple estimate or a more in-depth estimate, which takes roughly 12 minutes, in French, English, and German. The intelligent voice agent gathers and transmits information to a calculation algorithm which is fed from a property value database. Its final estimate is based on a number of factors, including rental yield, advertised prices and notarial deed prices.
“This new solution saves real time and enables everyone to obtain an estimate effortlessly, whether at home, in the car or at the office.”
Rudolphe Aben, Nextimmo managing director
Nextimmo describes itself as a hybrid real estate firm, blending a traditional agency with technology to enhance the customer experience.
A spokesman told Silicon Luxembourg that the firm is planning other models in the future, including an AI receptionist to help buyers or tenants search for a property on its website, to be launched in September.
While the service is unique in Luxembourg, Nextimmo is among a growing number of Luxembourg companies using AI in meaningful ways. While no official data exists on how many AI agents are in use across Luxembourg, broader European trends suggest adoption is accelerating, especially in areas like customer support, productivity tools, and document automation. Their advantages include 24/7 access and the ability to handle several calls simultaneously.
As more real estate services embrace voice AI, Nextimmo’s tool feels like a promising—if slightly rough—first step. It offers a glimpse into a future where getting a property valuation might be as easy as ordering a pizza. But whether these tools can match the nuance of a local expert remains to be seen.
