Q&A: How should we structure our SMSF to collect rent as a pension if my wife is only 56?

My wife and I run an SMSF. The fund owns 2
properties. My wife is 56 and I am 61. My wife owns 30%
and I own 70% of the SMSF value. I have reached pension
phase while my wife is in accumulation phase. How can we
structure/split the fund between pension and
accumulation phase so I can draw rent as pension for me?
(This is only an issue now. In 4 years', time when my wife
also comes in pension phase, we will be draw out
complete rent as pension for both of us). I am also mindful
of the minimum 4% pension withdrawal rule for myself. What if
the rent is less than 4%?
