Well technically it's an estate tax. It's paid not by the recipient but by the estate. However, there is a large exclusion ($2M) so unless this property is REALLY valuable (or the estate has other significant assets) none is likely due.
However, if by some chance there was a capital gain on the sale of the house, there could be some capital gains tax due. Since he would have received a stepped up basis when he inherited the house, any capital gain would be small unless he held on to the house for quite a few years.
