Be very careful before buying house in near future, reason:
1- Economic recovery is slowing and fear of double-dip is still looming.
2- Don't rely on all these calculators, think about your individual case yourself. Have you taken into a/c growing family once you have kids, one of yous losing job and future expenses.
3- I think if you can hold off for couple of year you will probably save 20-25% of current asking price.
Think before you commit yourself into something you regret later.
Best of luck.
