Medchal,
I agree that for the normal person, real estate is not a plausible "investment". But let's not forget that by default, real estate created a huge amount of wealth for the normal homeowner.
The S&P/Case index went from 62 to 190 in the 1987/2006 timeframe.
This means the normal person who didn't even consider their home as an investment at the time invested 20% as a downpayment, leveraged it 5:1 and ended up earning approx 1500% on their original investment. This was a huge amount of wealth that people were able to use for 'other investments', retirement or healthcare.
As of right now, this index has fallen into the 130 range so for now it's game over.
