According to her, one winner has to sell the house so they can pay the federal tax, so you might want to check into that.
So, our deal is, if she wins, she will have a huge party for friends for a month (O.K. maybe not that long), and then she sells and I get to represent her (just joking on that, because I dont' think HGTV has a Marin Home).
Disclaimer - I did not do research on this, but my friend is pretty reliable.
FYI, in Broward (Fort Lauderdale area) property tax would be an estimated $34,000 p.a. without including any exemptions. If that sounds not really appealing, the winner could of course always sell it and invest the money.
