I bought my 1st house in 1982. It was the much discussed 1200 sqft 3 bed/2 bath, in my case in Mission Village (near the stadium). It cost $87K and my 12.75% FHA mortgage was over $900 at the time.
I just looked in the same neighborhood and I think you could buy the same house with improvements for under $400K. Given current interest rates, I think it is more affordable today than it was 30 years ago.
