Advice on growing my wealth? I would like some advice on whether it's worth it to be doing RSP through POSB investsaver or getting REITS through robo-advisors?

The best way to growing your wealth will be a combination of gaining financial education, regular savings, control your spendings and investment.

The amount of growth will depends on what funds/equities or ETFs that you are going to RSP into. REITs do have both growth potential and provide a good source of dividend, but it lean more towards dividend potential in my opinion. Thus I believe the community will be able to better provide your with advice if you can idenfity your investment goal and risk tolerance.

Agree with Boon Tat that you should start reading and learning more first. It seems you have some misconceptions and more studying would definitely help. Cheers.
