If you look at the "Truth In Lending" (TIL) document that your parents signed when they took out the note it will tell you whether or not the mortgage is assumable. You can also contact the Lender and ask if it is assumable, as previously suggested. Either way you and your husband will have to qualify and have enough income to justify the additional debt load. Depending on what the terms are of the original note you may be better off just doing a traditional purchase with a new mortgage. My office would be happy to help you with the latter, if you so decide. Good Luck!
