it would seem to be a gift. I'm sure the value is in excess of the annual exclusion. therefore, the donor needs to file form 709. there are no income tax consequences to you, but you need to know the donor's basis and Fair value on the date of the gift. these items become important if you sell or gift the property to others.
at this time you have nothing to report except possibly property taxes that you paid if you itemize. hopefully, there was no mortgage, because outside of the income tax laws, most mortgages contain a due-on-sale clause. you would need to check with a lawyer as to whether the transfer of title constitutes a sale.
