Firstly I have owned a small amount of Intu for a few years. Initially did well - but now sitting on a loss. Not a very good divided payer ether. Hmmm, not sure why I own them - guess at this point just do not want to take the loss! They do own great assets though. Most of the pro's like hammerson more. I don't think having some UK exposure is a bad thing - but as they shares might be in the doldrums for a while, you might want to get a decent dividend while waiting for things to pick up.
My UK exposure is through Intu, Atlantic leaf (industrial/ great dividend), Redefine Inter (I wouldn't be adding) and Texton (SA REIT, with around 40% exposure to the UK, fantasic dividend but very unloved so wouldn't recommend, but after Capitec, my biggest holding). Did look at Capital And Regional - look well run, they like to sell mature assets then reinvest - decent divi as well. The other interesting one is Equities - on the surface looks good - modern logistics in SA and UK - good for the future I guess.
But, for me, would look at safer oversea investments first - no one knows what will happen to the UK. Sirus (germany, small industrial units, the great at developing sites) - NepiRockcastle (Retail, cover most of the CEE region but strong focus on Romania and Poland) - or Ecko Polska (just poland). I really like all three - as a region a feel Poland will do well with is population size as well as the poles are hardworking and value education.
