I don't think anyone can claim one way _or the other_ on this issue. Once you live in a place that is being used in some part to park mainland Chinese money, like I currently _do_, you really start to wonder why there aren't readily available statistics on this problem.
I don’t know enough to make a declaration. But I do know that she was renting the downstairs (it was a 2 unit apartment) for the past decade to the same people. Once this is a ghost house, no one will live there, thus one rental off the market. Is some demand artificially constrained?
