I'm glad you asked this question. Loan programs are currently changing (significantly). I'd recommend looking into a complete loan application and see if you can go beyond a credit score in qualifying. There are three 'parts' in qualifying for a mortgage loan.
1) Credit. If you're credit isn't great yet, I'm sure that we can work to improve it. I consider myself a credit expert, so I'd be happy to discuss some ways to improve it.
2) Income. Lenders like to see a steady flow of income and good job time. If you can document income, and you don't over spend - you're in great shape.
3) Assets / Reserves. You've got to have a little of money in the bank. This also takes into consideration down payment. if you have a down payment, your loan application is even stronger.
If you'd like to discuss your loan application further, I'd be happy to help. I work across Iowa and I'd love to be a resource for you.
Thanks again for your question.
