At sub 3%, I wish I could get a 45 year mortgage. I have a very healthy emergency fund and would like to use the extra money to invest more.
Sub 3% when inflation is at or above that number is amazing.
An investor with any type of discipline or luck can get a better return.
This is the first house I ever financed where I brought money to the table. Now I wish I had that 20% down payment to invest.
