TL;DR: Are you investing in real estate ETFs? Is that because you don’t own a house? What have you chosen? Why? Do you have a home-bias or only a world ETF? If you have a world one, are you OK with a large US weight?
If you don’t own a house I consider having some real estate exposure as a good way of diversification from stocks and bonds. I’m planning to do 5-10% in this area. (if you own a house you have a huge overweight of the “real estate sector” in a sense already, then I would do 0% personally)
I’m unsure whether a home bias is good to be honest, but so far am considering 25% swiss ones, something like DUPF, SRECHA, SRFCHA or some mutual funds otherwise. Or even some crowd/co- owned property. Not sure yet.
For the world part there are a few options: the usual expensive IE-one: GBRE or the cheaper US-ones: REET, RWO - but all of them have a rather strong weight on USA, something like 55-60%.
I’d prefer a smaller weight on USA, which could be achieved with 1 US-focused one such as USRT, IYR, VNQ and 1 ex-US one such as VNQI or perhaps CBHOUS which is europe only. It does start to look a bit messy though, but might be an option.
Anyone would like to share what they do, think?
