The situation may different where you live to here in the U.K. but I think renting is a mugs game. You pour money into someone else's pocket every month with nothing to show for it. We own two properties, one we live in and one we rent out which helps with income especially as we are both retired.
If you both curl your toes tomorrow I assume the mortgage will be covered by a life insurance which will pay off the outstanding debt leaving you a property to bequeath to your relatives, children or even a good chariy. (WTB&TS - ?? No, only joking!). Salaries will rise in the future and the mortgage will not sem so great.
I remember when we got married we bought a house and the mortgage was £30 a month! Relatives thought we were crazy. Over the years however, interest rates fell and house prices continued to rise. Interestingly rents also continue to rise.
Just a few personal ramblings
