A lot of people in real estate love doing 1031 Exchanges. If you're not familiar with the term, 1031s allow you to sell an investment property and roll your gains over into a new investment property -- rather than paying taxes on your capital gains. There are certain rules governing 1031s. The money must go directly into the hand of a qualified intermediary. You have 45 days to identify a new property, and you have 180 days to actually acquire that property. But there have been a lot of problems with 1031s because some qualified intermediaries are running off with the cash. Now The Washington Post reports that the IRS is retroactively disallowing some 1031s as a precaution.

Clark's real advice is to not do a 1031. People are so obsessed with avoiding tax that they lose sight of the bigger financial picture. For example, right now the max tax you'll pay when you sell a property is 15 percent. That's the best deal we've had in years. With the Democrats likely to get into office in 2008, most of their candidates are talking about capital-gains taxes of 28 percent. So doing a 1031 now to defer paying 15 percent when you'll later pay 28 percent is not "Clark Smart." Instead, just harvest your gains and pay your taxes! Clark knows everyone will tell you the opposite. But he believes the tax rates are only likely to go higher. This is best it's ever been; it's probably not going to get better -- only more expensive.
