Probably depended a lot on where you lived. Both my parents and in laws bought their long term homes in the early to mid eighties. Both were in the suburbs and were 2500sqft 4bed/2.5ba homes. My dad has mentioned that because he worked for Prudential that he got a special friend price on his mortgage at 10%. However, by the end of his mortgage he was paying less in mortgage then I was paying to rent a 3bed 1500 sqft house.McMansions weren't really a thing back then either. 1000 sq.ft. cottages and ~1500 sq.ft. bungalows/split levels/two stories were the norm for single family dwellings. The 'burbs were a thing (I remember "subdivision" and "survey" being slang for new housing developments) but they were nothing like today's sprawl. Look at old homes in established neighborhoods- a narrow lot with just enough room between your house and the neighbors' house for a driveway, but not always enough space to fit a car and still be able to open the doors.
We've had it really, really good in the McMansion era from about 1990 to present day...
... and it just occurred to me that population sprawl is an ironic tangent to take in a thread that is about a modern day plague.
