I get the not-buying movement. Not only do you avoid the commitment, but there is also the benefit of not having 6 figure debts to pay down. Let's be real- buying a home is one of the biggest financial decisions a person will make during their lifetime. It's a huge purchase. While banks and mortgage lenders want you to have 20% down, most folks don't have that initially. If you don't have that up front you can end up paying a high amount of mortgage insurance just to get your rates down (PMI, it's called). It can be a LOT to take in and it's not a surprise that more people are shying away from it. Also who wants to be paying on the same gosh-darn mortgage bill for the next 30 years anyway??!
If you are not currently saving for retirement or are not on track to meet your retirement goals, I would not recommend spending exclusively on debt, mortgage or otherwise. Even while you are paying off your student loans, you should still be making contributions to your retirement accounts- the earlier you start the easier it is! Frugal Rock is pretty lucky in that we had the ability to pay down our other debts in the past few years and since early 2015 have been car loan and student loan free. While luck has been part of it (finding good jobs, not having a lot of unexpected expenses), a solid plan to pay over and above the minimum also helped us pay those off early. It's felt so good, that we have no plans of taking out car loans in the future. As mentioned in an earlier post we are putting about 20% of our income towards retirement and are saving additionally on top of that- with an ultimate goal of early retirement (though hashing out that age is still uncertain).
