Not every moral issue can be encoded in monetary exchange, because of (among other reasons) unequal access to capital.
In general, yes, seeing trends in ethnic groups moving because they can no longer afford what was their home, even if to make way for another ethnic minority, is probably a bad thing.
I agree in principle, but the estimates for my own home on Redfin would beg to differ. The value of my condo at the time I purchased it seems to fluctuate every month. When I bought it I was below Redfin’s estimate by a few thousand, now it says I overpaid by like 30 thousand.
Just to be clear, I was referring to the estimate of the property at a certain fixed point in time (my purchase date) changing over time. I do expect current market price to change for my home. I was just saying that these sites will estimate a value that differs and shifts, even estimates of periods during which actual market price is an available data point. March 2017 may look like a great investment when you checked in January 2018, but really bad when you check in October 2018.
Anyway, I agree with you that the market is just what people are willing to pay.
Encroaching is such a strong word. Are they occupying property illegally or are they buying it at market price?
