the higher prices are affected by the corporate buying of single family homes. for every home a corp buys, that's one less for individuals to buy. if the number of buyers remains the same but fewer homes are available, prices go up--seller's market. yes, prices go up adjusted for..., but inventory more competitively sought. the other issue is that the average buyer is looking to buy with financing while corps are paying cash. that makes for such a smoother transition for the seller that it is hard for them to turn down cash offers.
after corps, we have foreign buyers also coming in with cash offers. i know of one specific house that is empty for the majority of the year purchased by foreign owners specifically for their kid to live while attending college. the kid chose to not go to that school, so the house sits empty except for when some property manager comes by to "check in" on the place.
so while this thread is discussing still showing decent ownership percentages, those numbers are glossing over some of the "trends" in modern real estate.
