Total nonsense. If someone has, say, a student loan, paying it off over many years before buying a house is simply stupid. And killing yourself by eating **bleep** is even worse idea - your heath will deteriorate, so your work will be affected, so your career will be affected etc. Or, if you are lucky not to get fat and sick, you will waste your youth. Enjoy life, have vacations. Buy affordable house as soon as you have 3.5% using FHA. Yes, you pay mortgage insurance, but IT IS CHEAPER than if you had to put so much cash out. Even when I have 20% down, I still use FHA and use the 20% in another investment. This works, as long as the value of the house goes up or as long as you can for sure afford the mortgage.
