As you have already read by now, consulting a tax expert or your CPA is the place to start for information related to your question. If you are interested in buying or selling real estate, you've got some great choices on this forum from which to choose.
As they say, only 2 things in this life are certain- death and taxes.
Real estate has many tax advantages though as opposed to other investments, so be sure to consult a cpa that has specific property knowledge that can take advantage of those benefits for your specific situation. Best of luck to you and your investment, Danny Barto
