You *don't* put appreciating assets into a Corp (especially a "C") because removing the asset is a taxable transaction, unlike with a LLC and/or partnership.  

Plus, with a C - there's the double taxation issue.

LLC's are generally the advised vehicle for real estate investments because of the limited liability component.  But, as Bill points out, if the LLC isn't handled/treated/managed as a separate entity that liability protection can easily be pierced.
