How often does one get a pay cut in comparison to a pay raise? Wouldn’t each upgrade cost you 6% anyways? That’s a lot of $ to throw away. If you have sufficient rainy day fund, wouldn’t it offset the risk of job loss in your risk calculation? Also, no one know your job security better than you. But if a mass market meltdown and widespread job loss occur, then it doesn’t really matter if you stretch or not, you’ll have no income to even pay for a mobile home, so calculate your own risk tolerance accordingly. No one know that better than you do.
