The best way to transfer title of the home that you want to give to your son for tax purposes is to enter into a purchase contract with him for its fair market value where he agrees to pay you a certain rate of interest on it yearly secured by a mortgage.Each year you then "gift" him a percentage of interest in the home equal to the amount allowed under Internal Revenue Service regulations which is roughly $13,000 per year reserving a smaller percentage in the home to you year after year.The way to do the above transaction requires an experienced real estate attorney and a certified public accountant to set matters in place.Good luck.
