Editorial context
Working with a provider in Basel – what matters
Before appointing a real estate agent in Basel, owners should establish which services their particular property requires. With a provider such as IMMOROSSI, which lists sales, lettings, valuations and investment property brokerage, these tasks merit separate consideration. Selling an owner-occupied apartment involves different documentation and buyer outreach from marketing a tenanted apartment building.
A market appraisal should be understandable in terms of its evidence and scope. Clients should ask how location, condition, age and comparable sale prices are assessed, and whether an initial online estimate will be supplemented by a site visit. For investment properties, it is also worth clarifying which tenancy and property records are needed for marketing.
Before giving instructions, owners should request a written breakdown of fees and services. Where a percentage-based success fee is subject to a minimum charge, the percentage alone does not determine the cost. The calculation basis, tax treatment, payment timing and any separately charged expenses should also be clarified. A separate quotation is useful for lettings.
Other points to agree include marketing channels, handling of confidential property information, viewing arrangements and regular progress updates. Owners seeking discreet marketing should discuss its scope explicitly. Finally, responsibilities for coordinating the transaction and the support included for notarisation and handover should be clear. These points provide general guidance rather than legal advice.

Absolut empfehlenswert. Die Zusammenarbeit mit Herrn Rosario Perri war stets sehr angenehm und wir wurden die gesamte Zeit bestens betreut. Hier wird man zuvorkommend, transparent und stets mit grosser Freundlichkeit und einem Lächeln unterstützt. Alle unsere aufkommenden Fragen wurden schnell und unkompliziert beantwortet und alles notwendige möglich gemacht. Wir Danken nochmals herzlich für diese wunderbare Erfahrung.
op Betreuung beim Immobilienkauf – absolut empfehlenswert! Der gesamte Kaufprozess meiner Immobilie verlief dank der hervorragenden Unterstützung absolut reibungslos und stressfrei. Von der ersten Besichtigung bis zum Notartermin wurde ich professionell, transparent und sehr engagiert begleitet. Besonders hervorheben möchte ich die ehrliche Beratung und die schnelle, klare Kommunikation. Alle Fragen wurden stets geduldig beantwortet, und ich hatte jederzeit ein gutes Gefühl bei jedem Schritt im Prozess. Auch die Organisation war erstklassig: Termine wurden flexibel abgestimmt, Unterlagen vollständig und rechtzeitig bereitgestellt, und ich wurde durch alle Formalitäten sicher geführt. Man merkt sofort, dass hier mit viel Erfahrung und Kundenorientierung gearbeitet wird. Dank dieser kompetenten Begleitung habe ich meine Wunschimmobilie gefunden und erfolgreich erwerben können – ohne St
Der Verkauf unserer Wohnung hat unkompliziert und unerwartet schnell geklappt. Der Erstkontakt mit Herrn Rossi und auch die folgende Kommunikation waren immer unkompliziert und freundlich! Herr Rossi hat sich von A bis Z um den Verkauf unserer Wohnung gekümmert und alles gut organisiert. Auch die Vorschläge betr. Notariat etc. waren perfekt und top seriös! Wir würden uns auf jeden Fall wieder an IMMOROSSI wenden. Nochmals vielen Dank Herr Rossi für Ihre tolle Arbeit!
Herr Perri hat mich sehr gut beim Verkauf meiner Liegenschaft begleitet. Er war immer verfügbar, alles unkompliziert, und hat alles von A-Z wunderbar gemanaged. Kann ich nur empfehlen.
Ich weiss gar nicht, wo ich anfangen soll – wenn ich könnte, würde ich 10 Sterne geben. Die Zusammenarbeit mit Rossi bzw. der IMMOROSSI AG war von Anfang bis Ende einfach top. Extrem unkompliziert, sehr schnell und trotzdem immer ruhig und professionell – genau die Kombination, die man sich wünscht. Kein unnötiges „Bla Bla“, sondern klare, effiziente Umsetzung. Das Inserat war praktisch sofort online, und innert kürzester Zeit war ein passender Mieter gefunden. Ich habe im Vorfeld auch mit anderen – teils bekannteren – Anbietern gesprochen und Offerten eingeholt. Im Nachhinein kann ich sagen: Das war Zeit und Geld, die man sich sparen kann. Rossi macht das wirklich auf einem ganz anderen Level. Verlässlich, strukturiert und gleichzeitig menschlich – das ist heute selten. Ich kann ihn von ganzem Herzen weiterempfehlen. Wer eine effiziente, ehrliche und professionelle Abwicklung möchte

Services in this field explained
A valuation estimates the price a property can achieve on the market, based on location, condition, size, fittings and comparable sales.
What does a valuation cost? Many agents offer an initial estimate free of charge. A formal market value report by a certified surveyor is paid; the fee depends on the property and effort.
When you sell, an agent handles valuation, exposé, viewings, negotiation and the notary appointment.
Who pays the agent's commission? When flats and single-family houses are sold to consumers, the commission is generally split between seller and buyer (§ 656c German Civil Code).
When letting, an agent takes care of listing, viewings, tenant selection and the tenancy agreement.
Who pays the agent when letting? Since 2015 the “orderer pays” principle applies to residential lettings: usually the landlord pays when they hired the agent.
