I don't want to sound like I am defending politicians (trust me, that's not my purpose at all), but it is important to know that this information is not true. There is a real estate related tax of 3.8% in the new Health Care Bill (which is not good for the real estate industry), but it will NOT affect ALL real estate transactions. In fact, it will likely not affect anyone selling their primary residence. Nonetheless, this is something real estate practictioners and investors should be aware of...and upset about.
You can read the details about how this might impact real estate investments at this article from The National Association of REALTORS and here is a clip from that:
"...when the legislation becomes effective in 2013, it may impose a 3.8% tax on some (but not all) income from interest, dividends, rents (less expenses) and capital gains (less capital losses). The tax will fall only on individuals with an adjusted gross income (AGI) above $200,000 and couples filing a join return with more than $250,000 AGI."
