The factors that many of us took into account when telling you not to buy a house before are still there. I understand what it is like to want to move into a house right away.
I also know what it is like to work two jobs to support the bills. I have a client who was working two jobs five years ago and they bought a house on an emotional whim (regardless of our council). The husband called me a couple of months ago after being laid off and told me that they were in a panic and needed to sell. We talked about their situation and thankfully they have equity, but now need to part with their dream home because they got emotional and bought something that they shouldn't.
He really has three choices now.
-Lose the house they love to foreclosure
-Work three jobs until he can find good full time work
-Sell, but do so with an aching heart because they love their house.
No matter what happens you will need to work two jobs for the next thirty years just to keep the ball rolling, and if something should happen (job loss, injury, etc.) you are stuck in a terrible position. It has little to do with your income but more to do with your overall situation. There is no doubt that you qualify for a loan, but I wonder if you asked each of the people who are in foreclosure right now (who also QUALIFIED for their loans) whether it was worth it or not, what they would tell you.
My advice is to get off the emotional train, stop looking at houses and start finding the cheapest apartment you can tolerate. Once you move in, work as much as you can and pay off your debt as quickly as possible. Once you are debt free save up a downpayment (20%) and then buy a house. This may be old school conservative advice but very few of the people follow it find themselves in mortgage trouble.
By the way - there will be good deals then too.
