My mom has cancer and is at a skilled nursing facility. My dad is having back pain issues and arthritis. If they are both in a skilled nursing facility, what happens to their home?

They will be private pay as long as they have assets. If they are both in a nursing home and no one lives in the home, once their assets run out, Medicaid may want the house sold or put a lean on it. You'd have to check locally, as Medicaid is locally administered. But most likely, it will need to be sold or at least a lean will be placed against it for whatever they owe. An estate attorney or elder attorney could be useful here.
