answer: #Person1# advises to sell the current apartment and buy a new apartment. Then #Person1# and #Person2# decide to take out a loan.
documents: #Person1#: Our current apartment is valued at RMB 700, 000. We can sell it and put that money towards buying the new apartment.
  #Person2#: Yeah, but we still need RMB 500, 000. Maybe we can use some of our savings to pay part of it.
  #Person1#: And we can take out a loan to pay the rest.
  #Person2#: Great, so we can afford the new apartment after all!
  #Person1#: Uh huh. . . but we're going to have to cut back on our shopping from now on.
