Some high real estate value east coast suburbs experienced a phenomenon of Chinese cash buyers, buy a house larger than any personal need, park wife and kid away from CCP. Hedging political risk.
If I recall, around 2016, near me, this process cooled off somewhat.
I personally observed the uptick in middle aged Chinese women walking in the neighborhood, usually alone, often limited English.
More than one real estate agent remarked at the time that houses in a certain area of town were going for crazy amounts, as in nothing to support the valuations, all cash, and those offers were coming from Chinese people. It was an area of a few blocks. Couple blocks away, it was still a strong market, but there was no runaway increase. It is all the same schools, same zip code, etc.
At this time, there is an informal Chinese running group in town. I have no idea if any Chinese speaker who was not Chinese would be welcome.
BTW, cash offer means buyer just transfers funds (not literal greenbacks) at the time of close, no mortgage. If you have some other way to borrow, you can do that, but it has nothing to do with the real estate deal. The money goes in a trust account of some kind (lawyer or title company) and a representative hands certified checks around at the closing table.
