Tax on trading properties?

[Daniel Pena]

what are the tax implications of trading one property for another without any cash changing hands? My father has a commercial property that he rents out and someone wants to trade him for a single family house. If he does the trade he would use the house as a primary residence. The difference in what he paid for the commercial property vs the home value is about +100k, that is why I am thinking there may be some tax implications. I told him to go talk to a tax attorney but would like some input from biggerpockets.
