It's a small homebuyers incentive, after all. This weekend only, anyone who buys a custom built home from KB Home Mortgage, a subsidiary of Bank of America [stock BAC][/stock] will receive as part of the package a "Walt Disney Dream Room." The construction company will agree to deck out a fully-licensed Disney-themed room in the home with either a calming green Classic Pooh theme, a royal Cinderella 'palace', a chic Cars room or a – gulp – Hannah Montana Hangout so a kid can “take a break from the spotlight.” Sorry, Little Mermaid fans, there's just no room under the sea for other dream room designs. However, even if a potential buyer who visits a KB Home over the weekend can't decide right away, they can still pick up a Disney Beanz plush toy (again four choices: a Mickey Mouse, Minnie Mouse, Goofy or Pluto). The estimated retail value of the room is between $1,349 and $1,669, and homebuyers must finance with KB Home Mortgage. It's another example of developers trying to boost demand, as the US Senate toys with the idea of extending the first-time homebuyer tax credit. After all, with housing prices where they are now, it’s the perfect time to buy a new home “at a price that’s just magical.” Write to Jon Prior.
