Further nit: while it is true that there are two types of property, real and personal, there are also several different uses of property, such as investment use, business use, and personal use. So one can refer to personal-use real property, such as a residence, versus business-use real property, such as an office building. It seems TFA doesn't address commercial mortgages at all.
