I want to understand if the 401k loan interest schedule is different from a mortgage interest schedule. For example, in a mortgage payment the interest is the most of it. Is it the same with 401k loan?
Reason for asking is to see if it makes financial sense to use 401k loan to pay off a mortgage on a property. Thanks!

We’re beginning our retirement savings, and are not sure why our money market isn’t the best place for the money; I assume for tax reasons.

I would like to open a Roth IRA. Do the interest rates or rates of return differ between Vanguard, Fidelity, my personal bank, etc. just as the interest on a savings account a different banks would differ? If so, do these rates fluctuate daily? Does anyone know whose rates are consistently higher? Can I have more than one Roth? Can I have a Roth AND a Traditional IRA?
