Commercial properties, (retail shops, factories, warehouses and office spaces) are in a very different league residential property and out of the domain of the every-day investor.
Whilst there are many benefits of investing in commercial properties, they are more suitable for the sophisticated and experienced investor, particularly as they are more yield-driven than capital growth-driven.
Consider it this way: for most advanced investors, your job is to build your asset base.
Once your portfolio is big and robust enough, you begin transferring into a cash flow strategy and at this point, a commercial property can be a good investment.
