I think it's hard to compare the interest rates today with those back then. Although interest rates are lower today, property prices have increased many times over. I believe they cancel each other out in the end.
EXAMPLE: Here in Berlin, the parents of a friend paid about 120,000 DM for a semi-detached house with a 350m2 plot of land (the land itself). Today, you have to pay around €120,000 and up for the same plot in a similar location. The low interest rates don't help me much there. Today in Berlin, the price per square meter of land is €400-500. Back then, it was about 300 DM, which is about €150.
