RE:BPOBPY website lists BPO prefers and their details.
Preferred Shares | Brookfield Property Partners C,E,G,I have an interesting extra feature, minimum rate. If you think rates are going back down to zero, this feature would be valuable.
I think they are all a buy, but which is "best", hard to say..... each person is different in their needs, timing and where they think interest rates are going.
All just my opinion/view/thinking
