In most states and circumstances it is usually better to hold real estate in a living trust so that it would pass directly without the expense and delay of probate -- and the same step up basis for income tax purposes applies.
While in some states a primary residence home held in trust may not qualify for the homestead exemption in the event of bankruptcy, if this is not a real concern, I don't understand why the advice was given to him -- unless there may be a special reason or circumstance that I am not aware of or it involved a type of trust that is no longer appropriate.
