Should I sell property and max pension contributions?

Now you're changing your argument suggesting there are no capital gains?,
Today he might not have capital gains... I'm talking in the future.
My point is the percentage tax would increase.. Do you disagree? Do you need to pull in others for support?
If you don't understand the point... Don't comment.
 
Thanks for this - I had completely forgotten about the CGT rule and assumed I would have to pay the entire 33% on any gain. Changes things marginally but probably not in favour of keeping.
