in the big picture, clearly neither would be a mistake. maybe you can squeeze out some sub-percent returns the one way or the other, but it will be overall very good. take 1h time to make a dedicated excel, and you will know the answer to you question afterwards.
big question. however, “moving around” will not affect your long-term investments any different than other (normal) forms of investment. your bond alternative is also a valid way to invest your money. you seem aware of the tradeoff between risk and return.
to me the question boils down to whether you want to reallocate your fund for real estate later or not. if so, the bonds are the safe bet (assuming you need the money for the house). They are less prone to a potential market crunch that might come and might not be overcome 7 years from now.
If you won’t reallocate, then the clear answer is to go more equity.
since you can’t tell for sure what will happen, all this is speculative. one (arbitrary) answer to uncertainty is splitting your portfolio into equity and bonds, like the classic 60/40.
in the end you need to sleep well with your decision on inestment. there is no way around you making up your mind yourself. feel free to post any questions
