I know this is true because I speak with professional investors and brokers  every day virtually every broker and investor I deal with does not know how to do the math the so that you can double your investment capital every 1 to 2 years.

An ARM product can be a great way to save now, but if you are not planning on living in the property beyond 1 or 2 years, it may not be ideal.

Not ideal, but the current owner has had health issues that have deterred from fully leasing the building.
