Quote from Ghost of Cutten:
Don't forget to consider the capital gain. If your home appreciates 5% per annum, and you put down 20% (200k), you will turn that 200k into 2 million in 15 years. That's better than 15% per annum, and it's totally tax free. It also requires zero effort and you get to enjoy ownership over renting, and it's diversified from your trading/investing gains.
LOL, where do homes appreciate 5% every year for 15 yrs?
and no, the $1m gain in your example is not totally tax free. the limit is $250k/500k single/married.
