Do you like your current job? How long have you been there? Are you confident that your position is stable, and are you expecting annual raises and bonuses?
Of course, you can never be 100 percent certain that your job is secure, but when you're looking into buying a home, it's a good idea to take an honest look at your workplace's climate. Have there been rounds of layoffs? Have you heard of more? It's much easier to break a lease if you suddenly can't afford it than it is to sell your home. If you feel like your current job situation is iffy, you may want to hold off a few years on such an important purchase.
