If you're looking for homes in Palo Alto, Calif., our sympathies to your bank account. In the most recent example of home prices gone bonkers, a two-bedroom, one-bathroom cottage has been listed for $2.6 million.

At 900 square feet, that means you'd be paying more than $2,800 per square foot -- an eye-popping number more typical of a luxury penthouse in Manhattan than a suburban neighborhood. The cottage has a detached garage, but only outside basement access for the laundry room. There have not been any offers yet, though realtor Laura McCarthy says she had a number of showings.

If the price tag sounds far-fetched, consider that a house down the street was originally listed for $1.8 million and recently sold for nearly $2.25 million -- and it was uninhabitable.

"And when you look outside this bubble, it's really crazy. But this is reality for here," McCarthy said.
