Agent: “Good day, this is Anna Weber from Müller Immobilien GmbH. Am I speaking with Mr. Mustermann?”(Pause)
2
Agent: “Exactly. A few days ago, you showed interest via our online listing for the 3-room apartment in Prenzlauer Berg. I wanted to ask if you would have time to schedule an appointment?”(Pause)
3
Agent: “Great. I still have appointments this week on Wednesday at 4 p.m. or on Friday at 10 a.m. Would either of those times work for you?”(Pause)
4
Agent: “Friday at 10 a.m. is currently best, because there are more viewings scheduled afterward. If you prefer, we can move the appointment to 11 a.m. – would that be okay?”(Pause)
5
Agent: “Great, then the appointment is set for Friday, June 6 at 11 a.m. The address is Schönhauser Allee 45, Prenzlauer Berg. I’ll send you a confirmation by email shortly. Do you have any other questions about the apartment?”(Pause)
6
Agent: “The monthly utility costs are approximately 250 euros, including heating and water supply. There isn’t a private parking space in the building, but there’s a parking garage on the street, where we can help you arrange a spot if you like. Is that okay for you?”(Pause)
7
Agent: “The deposit amounts to one month’s rent. Move-in could be as early as July 1st, if everything works out and you decide to proceed. I’ll summarize all of this in the email. If anything is still unclear afterward, you’re welcome to call me anytime.”(Pause)
8
Agent: “You’re very welcome. See you Friday, Mr. Mustermann. Have a nice day!”(Pause)
