I am currently selling an unoccupied condominium in Vienna.
As it was a small flat, a prospective buyer who had recently bought a flat in the same building was quickly found. However, he offered a much lower purchase price than the seller wanted.
The customer really wanted this flat and improved his purchase offer, stating that this would be his last offer. In addition, the purchase offer was only limited to one day, which is extremely short.
After a long back and forth, the seller was prepared to accept a lower purchase price if the prospective buyer increased his offer by a further EUR 5,000.
I managed to persuade the interested party to increase his purchase offer again, the chances were then good that this would be accepted, but with a longer time limit of at least 3 days, as the seller was on holiday.
I also informed the interested party that I would have 3 viewings in this flat on the same day to show that the demand for this flat was very good.
In the evening, I had 3 viewings in a row. However, I was really shocked when I couldn't unlock the front door in front of the customer. The whole thing was more than embarrassing! The key, which had last effortlessly locked both security locks, no longer fitted into the bottom lock.
In the meantime, the next interested party had joined us.
I excused myself and went to my car (where I kept all the property keys) to see if any keys had been dropped. On the way there, I quickly called the owner, who was in the sauna on the boat. His wife picked up the phone and I explained the emergency to her. It only took a few minutes before I had the seller on the phone.
During the conversation it turned out that the same key locks in both the upper and lower security locks and gave me the telephone number of a neighbour who also had a key to the flat.
When I got back, my third prospective buyer had arrived and a lot of people had already gathered in front of the flat door. They all wanted to help me unlock the door.
