Your age cannot be used in determining whether or not you qualify for a loan. Your credit score, income, and debt to income ratios are, however.
If your credit scores are acceptable, and you don't have a large amount of outstanding debt relative to the income you are bringing in each month - you shouldn't have a problem securing financing. That said, your total yearly income is around $18000, so the price range/amount you are financing is going to have to reflect that.
I would contact a mortgage professional who can run your numbers and advise you of your options.
Hope that helps!
