If you're only approved for a $50,000 mortgage you may want to look into the USDA Direct mortgage since they can subsidize the mortgage through below market interest rates. By subsidizing the mortgage, you should be able to qualify for a higher purchase price which will give you more options.
Call the local office in Temple on Monday and ask about the USDA Direct mortgage.
