The best answer may depend on what Dad's intentions are for the house in the long term. Does he intend for it to be daughter's family's house forever, or to keep it in his name and possibly pass it to someone else upon either his death or that of the daughter? If this daughter is the sole heir to his estate, it can be done pretty simply with most common estate-planning vehicles, including by will, trust or beneficiary deed. Which of these is best depends on Dad's other assets, other beneficiaries and a number of additional circumstances that weigh in to the decision. Tax ramifications should certainly be taken into consideration, too, and there are several options to minimize or avoid entirely any such consequences here.
Your question is a very good one, but it really leads me just to advise that Dad should talk with a competent estate planning attorney with a real estate background who can help him to evaluate all options and decide on a best course for this transaction. Our office would be happy to offer a free initial consultation to discuss it with him.
