According to a recent issue of Commercial Connections, a print and web publication of the National Association of Realtors the several proposals to repeal or limit 1031 tax-deferred exchanges in the 113th Congress were not adopted. Read about it here. However, new proposals and plans tend to borrow heavily on previous ones so expect the 1031 tax-deferred exchange to remain vulnerable.
My advice to sellers: Why wait to complete your exchange? We are in the midst of a robust, fully-recovered market.
