What is the difference between addy and a REIT?
Is addy a REIT? No.
A REIT lets you invest in a "basket" of properties while addy lets you choose the specific address that you are investing in. More on the differences here.
An analogy we like is:
REIT = Music Album
addy = iTunes
With addy, you can pick and choose the specific song (ie. address) you want!
