You should be able to qualify fine but we would need a survey showing the home only on up to 10 acres of the land. The contract can be written for the seller to pay for the survey and with the other 40 acres at no value as long as there are comparable properties to support the value of the home and 10 acres.
I am in your state and would be glad to help you.
