#1 reason to consider is for family…aging parents, grandparents, kids growing up / schools, etc.
The only financial reason we can even come up with is that we don’t have any real assets and there is some chance (although pretty small) that the world economic system could go haywire with all of this money printing, etc going on.
The #1 reason to not move forward would be the uncertainty in the economic outlook currently–there is some chance (certainly more than the chance of the above…in fact it may be closer to even odds) that we are in a longer term deflationary environment which will erode value in housing over time and given the debt bomb we could see some spasms. Again, per above, Helicopter Ben may just fire up the money printing machine.
