I was curious about this, so here's a bit more detail.
Interest rates were quite high (and surprisingly variable, as a modern observer) in the early 1980s, peaking at almost 20% and spending a lot of time in the teens [1]. However, the median house price [2] was still low relative to median household income -- at the interest rate peak of 18.9% at the end of 1980, the median house sale price was 66k, and the median household income was 21k [3], for a ratio of about 3.1. In 2022 the median house sale price was about 450k, and the median household income was $71k [4], for a ratio of about 6.3!
I think the mortgage rate difference does mean the 80s were still worse if you took out a long mortgage at the given rates. However, 1) you could also save for much less time and buy a house with a smaller mortgage, and 2) there seem to have been a lot of since-closed loopholes [5] like assumable mortgages (from my limited understanding: you essentially take over the current owner's mortgage, along with its lower rates from when they bought house) that meant a lot of people were technically buying houses with much lower effective rates.
So ... I question the claim that the early 80s were easily as unaffordable as now.
