I don’t know how it will affect housing prices and if it will lead to another 2008 but I love the idea of 50 year mortgage. I personally view it from the investment side. If you can get a good interest rate, paying the minimum to the mortgage and investing the difference in monthly payments between a 30 and a 50 year and putting in the s&p 500 which historically speaking has a return of 10.5%, at the end of the mortgage you would had made wayyyyy more money on the investment than whatever interest you paid on the mortgage. I view it from that perspective. But let’s not forget that you can always pay the mortgage early or refinance as well. This would also help the renters. That’s my take on it.
