If anyone is thinking about whether or not they can afford a specific house payment...

Just do a little home work.

Step 1:
If you don't have a budget, then figure out how much money you spend and start adding it up.  It's best if you have at least 1 years worth of information to go off of.

Step 2:  Subtract your expenses from your income and see what's left.

Step 3:  Check your numbers and ask yourself a few questions.
How much does that leave for a mortgage?
Did you leave any room for saving money for a rainy day and unexpected bills?
