From reading the list it’s clear it’s from living in a low cost suburban low rise 1960s-80s apartment complex — which tend to be the defacto standard for international graduate students - average frame construction, low cost electric appliances, cheap to replace mid pile carpet, the cheap vertical blinds, the cheapest glacier bay dual valve faucet [1] - all very efficient to manage and turn over. They have convenient parking and decent amenities for the price. In the rust belt/northeast these complexes are 90 percent (made up number) international and some domestic students and old people (there isn’t much difference in these places and most “senior living” places outside of what’s on the sign out front)
