The occasion was a housewarming. I found that Richard had recently moved. They used to live in more or less the same area. Now they could afford a bigger and nicer house. But it wasn't quite his own. Richard explained that houses were very expensive there. So he had made a down payment of 30% (percent) and borrowed the rest of the money from a bank. He would have to pay back the loan over 30 years.
The table was already set for company. Soon friends and neighbors started arriving. The party was a great success.
