Commercial real estate is generally held for 5-10 years. During this time the investor can build up equity through the pay down of debt, see rent rise and realize appreciation through the dynamics of supply and demand. At some point their equity would be more effectively invested by selling and upgrading both the quality and size of the investment. While it is not the commonly done investors can also sell there individual interest before the entire property is sold. By its nature commercial real estate is a long term hold with less liquidity than a stock or a bond. Selling any commercial real estate including TICs early can be economically undesirable.
