If you are doing this sort of evaluation do not forget to consider the taxes, which can shift things remarkably based on your jurisdiction.

If one sold the property and invested the rest you will be paying some sort of taxes on the investment returns (at varying rates depending on the investment), while with the property it may be possible that the taxation could be low to nil. By writing depreciation of the property against your rental income it is possible you could pay no tax at all.

Also do not forget to consider various costs associated with the sale of the property.
