We thought about moving to London a few years ago, and even then _all_
houses that were close to the underground (i.e. its stations) tended to
be very expensive. ;-)

There is "expensive" and "expensive for what they are"
[accommodation-wise].

In the context of the OP's question, I guess we are talking about houses
(of any kind) over 3/4 million.
