@William thank you for the explanation.I just see this term used a lot more frequency and can't help being curious.I speculated what could have prompted that too and the only scenerios I could come up with is a trailer home being hauled out, or something like erosion, where a landslide eliminated a significant portion of the land, or a hurricane hitting the beach and took out some parts of beach front land...something crazy like that.In the case you mentioned, someone actually moved a house?

When determining whether services performed by a corporate officer are considered nominal or minor, IRS agents examine the character of the service, the frequency and duration of the performance, and the actual or potential importance or necessity of the services in relation to the conduct of the corporation's business.Example: The officer of the corporation perform only minor ministerial functions entailing a few hours work a year for the corporations.

Rental frequency might be better for a 1 or 2 bar house vs 4 bar on Long Island, unless it's a hamptons house, in which case you have many regulations to consider.
