There is, I believe it falls under the capitol gains taxes. Basically, you sell your house, the equity gained over investment (You paid $100,000, sell for $200,00, that $100,000 growth is taxable. Not what you pay in, but what it grows.) is taxable like income. But, if you reinvest in another piece of property (This I have no clue on except if you buy another bit of land or a house then that qualifies.) then you're exempt from paying taxes on it. The catch, eventually that property will be sold and cashed out, whomever does that get to pay up, depending on the actual situation and all.
