He can either gift the house to you or sell it to you, at or below market value. Either can be done for little more a few hundred dollars on recording fees (though you should also have a real estate attorney help you, which will cost a few hundred more, to make sure everything is done right).The real issue though is taxes: different ways of transferring the home will have different tax consequences for both you and him, and the tax consequcnes can be considerably larger than the fees. Speak to a CPA about the tax impact of gifting it, selling it at market, and selling it below market, to see what makes the most sense for you; then have an attorney draw up the papers and help record them.
