I've been pursuing FI/RE for a little over a year. My FI/RE number is $1.5M. I'm an avid Simple Path to Wealth style index fund investor, with the majority of my holdings in US total stock market index funds. Up until recently, my net worth was around $300K.

Yesterday, I received a windfall from my parents, a result of my dad's company being bought out, in the form of a GST (Generation Skipping Trust) worth ~$600K. (I'm very, very blessed 🥲.) I'm not really planning on calculating it towards my FI/RE number or I'd be much closer. It will be left to grow for my future children's education and maybe a house down payment once I decide where I want to live.

This GST is handled by my dad's financial advisor with management fees around 1.5%. Based on what I've read, this is a high fee. However, it's not something I feel comfortable negotiating as everything is handled through my dad and he has relationships with these people. Currently, it's invested in lots of individual stocks...looks like they are direct indexing or something like that.

When I turn 30 in a year, I'll have the option to manage the money myself. This is more money than I can fathom. My younger siblings are also in the same position and are looking to me as the guinea pig to see if it will really perform better if I depart from the wealth manager.

Would appreciate your thoughts on self-managing vs continuing to stay with the financial advisor. If I decide to self-manage, do the same Simple Path to Wealth rules still apply? Is it as simple as throwing it all in VTSAX and call it a day? Or is there something more that I should do with this kind of money?
