The principle and interest payment would equate to 30% of your gross income. When you tack on taxes and insurance, you've exceeded the typical 28% front-end ratio that many lenders use as a hurdle. The limits are tied to the type of loan, FHA use to push as high as 29% and some conforming loan sources would go as high as 33%.
The next thing they have to consider is your other consumer debt. When combined with the above debt, the ratios should not exceed 36% on average, although FHA may permit as high as 41% and some conforming loan sources will go as high as 45%. Note FHA had tightened and then loosened some qualifications, so check with a reliable lender that is recommended to you by a trusted source.
However, even if you can qualify, you're putting very little down (6%), and you're pushing the edge of reasonableness on your housing expense. Tread carefully, since the downside of over buying is pretty negative all the way around.
