Alice replies within a few hours. No commitment required.


We walk you through every finding.

Your inspection isn't just a checklist—it's a conversation. Alice explains every defect in plain English, shows you what to worry about and what's cosmetic, and gives you the confidence to negotiate or walk away.

We also review the WEG collective finances—Hausgeldabrechnung, maintenance reserves, and planned special levies (Sonderumlagen)—to flag hidden costs beyond the walls.

Your report is your negotiation tool. Every defect comes with a repair cost estimate—clients regularly use our findings to negotiate €10,000–€30,000 off the purchase price.
Case Study · Altbau, Charlottenburg

The apartment looked great. The building didn't.

The apartment itself was in good condition—but we don't just check your four walls. Walking the staircase to the top floor, we found mould and a saturated damp wall. That's a building-wide issue, not a cosmetic one.

Top floor: Mould & saturated damp wall
Basement: Unresolved sanitary issue—insurance claim rejected

Without checking the WEG documents, the buyer would have had no idea the building insurance had already rejected the claim. Potential collective repair costs: €20,000+, outside the Erhaltungsrücklage—meaning a Sonderumlage for every owner.

This is why we check the whole building—not just your apartment.

"We contacted Alice for a survey before putting down an offer to buy an apartment, and she was fantastic. She checked everything, did a water damage check with specialized gear, read through the building's meeting minutes and documents. The report was meticulous and detailed, delivered within 24 hours. We highly recommend booking her!"
