I would rent some more and save up money...houses are money pits (they are great, don't get me wrong, just waaaay more expensive than apartments). $2,200 isn't really that much money and financially, it doesn't look like you're ready to own a home.
Let's say you put that $2k to a down payment - then you have zero left over for emergencies like the car breaking or having to pay a medical bill, etc.
Also, I think the housing market will continue to be in a downturn, which is great for you because it means when you are ready to buy a home, they will be even cheaper than they are now.
Don't rush. Use this time to build DH's credit, save, and research the towns and neighborhoods you want to look in when you're ready to buy a home.
Also, for the future, what the bank tells you you are approved for and what you can acctually afford may be two very different numbers. The bank only looks at income and any loans reported on your credit report. This doesn't include any bills or utilities you have or other costs you pay for. Only student loans, credit cards, car loans, and home loans would be on your credit (or any utility or medical bill that charged off and went to collections). So, it's up to you and your DH to figure out how much house you can AFFORD.
The percentage is typically 30% of your gross or before tax income. For example, if you earn $100K annually before taxes, 30% is $30,000. Take $30,000 and divide that by 12 months in the year - your housing payment should be no greater than $2,500 per month. You can do the math with your own income. Be sure to use the before tax figures.
