Just my personal opinion - with your income you should probably pick only 2-3 instruments and focus on them.

Nothing wrong with funds and stashaway (I’m personally using them too), and you already start investing in properties already so thats a good start. You also have ASB loan (forced savings/investments). But before you start investing anywhere else, its probably a good idea to max out your ASB allocation (200k+200k)

My take on stocks is to dump 7k-8k one shot depending on which broker you using to minimize transaction fees. Also there are better ways to invest in S&P ETF other than stashaway, link here https://forum.lowyat.net/topic/4744515

Just my two cents overall. But bottom line is, its great to start investing earlier 👍🏻
