Look, I can understand why John McCain has trouble counting his houses. Are we talking properties? Addresses? Homes? Because when you have a massive ranch with a half dozen homes and four addresses on it, things get confusing.
From a press report on the barbecue McCain threw for the members of the media (no, Mother Jones was not invited) in March:
McCain said... the Hidden Valley Ranch [in Arizona] got its name from the horseshoe shape of the creek that runs through the property.
He said he built the first house on his property 24 years ago and now there are six houses on his lot.
The addresses on the ranch are 11455 E Hidden Valley Road, 11445 E Hidden Valley Road, 11415 E Hidden Valley Road, and 11405 E Hidden Valley Road. I'm going to go ahead and assume that's a sizable ranch.
Here's the closest to a full account of the McCains' properties that I can find. It's from the Politico story that revealed exactly how extravagant the McCains' spending is ("Their credit card bills peaked between January 2007 and May 2008, during which time Cindy McCain charged as much as $500,000 in a single month on one American Express card and $250,000 on another"):
