Paying for Underperformance

I am 27 years old and recently inherited about $700,000. My family has a financial advisor through a more prominent firm, but I can not trust the guy. He is charging +2% fee on our total sum. He got a lot of customers, so I feel like he does not have enough time/energy to focus on my wealth.

I have been studying/reading and thinking about doing it by myself through Vanguard's index funds. I'm thinking put majority of my money in couple index funds and let it sit for years without making adjustments. However, I am pretty scared that I'm going to blow all my money.

Some say I should hire a financial advisor, but it seems like FA are all trying to do whatever is in THEIR best interest (although they say that they will be my fiduciary).

Edit: I'm sorry. I don't think I was clear regrading the fee he is charging us. 2% is one time fee as long as I leave it in that designated mutual fund. What I meant by total sum is $ I will put into a mutual fund and after that i guess there are some "hidden" fees. I guess the fee is set by each mutual fund company and he gets a little portion of that 2%.

I was paying an advisor $8k per year. He never beat the market and often underperformed. Lovely guy, but once I had enough time to look into it all (the lack of time is WHY I got an advisor in the first place), I realised I was being utterly reamed given the size of my portfolio.

Both of my parents saved their money with one of the giants in this field (as tempting as it is, I will not name them). When you visit their offices, there is lots of polished wood, hushed tones, and big conference rooms as they very seriously do their job of turning the assets entrusted to them into more money.

I was executor for both of my parents' estates (they were divorced), so I got an up-close-and-personal look at what the investing company was doing, but only after the fact. My father thought of himself as a savvy investor, so he managed his money himself. He was, in reality, the epitome of the “Poor Dad” and couldn’t find a good investment with a flashlight, a compass, and someone pointing him right at it.

My mother was the polar opposite; she totally trusted this investment company. Over more than 50 years, they both managed their retirement assets this way. While my mother “won” this race because she had more money when she passed, the fact is that if you look at how much money she handed over to them and how little they actually did with it, it’s just sad.

When it was time to unwind her accounts, she was diversified to the point of “diworsification." There was no rhyme or reason for what she was invested in. It was as if the plan was to see if there was a possibility to buy a little bit of everything. She was in every high-load mutual institutional fund you could possibly find, and a smattering of international institutional funds as well. What a mess.

They wanted to hand this over to the heirs as-is and not sell any of it. I insisted they cash all of this mess out and only transfer the money to the heirs. They did this for everything except her IRA, which they transferred as-is. I received $13,000 (give or take) worth of 20 different mutual funds. That’s just nuts.

So, don’t be swayed by the big conference rooms and the fancy offices with their name on the top of the building. These folks are totally in it for themselves, and if they make you some money, it was by accident.
