I just met with a potential buyer yesterday who wants to purchase a home in NW Austin and has a similiar story to yours, so I'm very familiar with your situation. You'll want to find a lender who can consult with you about how to get your credit score improved - it can happen faster than you may think! Lenders also consider your debt to income ratio, which would include such things as car loans, student loans and credit card balances. Finally, lenders are looking for job stability, so if you have been at your current job for less than 2 years, they'll weigh that into the equation.
The lenders I work with are like a part of my team, and we work together to help buyers get qualified as fast as possible, then guide them through all the steps involved from contract to close. I would love to visit with you and connect you with my lender team.
Don't give up on your dream of being a homeowner - it will happen!
