Bill Gates' home tour on charity auction block

A tour of Bill Gates' mansion in Medina is going for a hefty price tag. The bid to tour his house (and have him guide you around) is up to $35,000. Last year, the tour sold for $8,600, the Seattle PI is reporting.

But before you run out to start bidding, it's only available to those who work at Microsoft as part of its annual charitable giving campaign. According to the Seattle PI, word slipped that the bidding was on the rise this year from Microsoft CIO Tony Scott at the Society for Information Management's SIMposium on Tuesday.

The Seattle PI is saying that employees can also bid to go on a run with CEO Steve Ballmer and the opportunity to buy the "World's Best Bologna Sandwich." But it's the tour of Gates' house that receives top billing every year. And for good reason--that thing is huge.

But all this talk of going on a tour of Bill Gates' house begs an important question: how much would you pay to talk a walk around Bill's house? Let us know in the comments below.

And just to start things off: $500. That's my limit.
