My wife and I are both going to open an IRA each this week for 2016 earnings, and would like to choose a company for it.
We currently have 403b accounts with TIAA-CREF, and their rep said they could do an IRA and that since they are non-profit, their costs were lowest one could find. (And not everyone can use TIAA-CREF, as it is just for educators and their families, I believe). In some ways, going with TIAA-CREF would be convenient, since we already have other accounts with them and can just use one login and access everything (though really, that's not that big a deal).
The other company I spoke to was Vanguard. I had been told they have low costs as well, and their rep said they had the lowest costs (so which is it, guys?). I may later want to also buy some index mutual funds and had always heard Vanguard had the lowest costs, so starting with an IRA through them may be good in this regard.
Is there anything obvious that would make or break this decision for me? I've been truly stupid with financial decisions and would like to start amending that, one step at a time, such as this choice. Thank you.
