Thank you all for your replies. Just got word back from my wife's new place of employment that she 1) cannot rollover at the present time, but 2) could rollover at time of account opening (roughly May 2017).
They seem to be dragging their feet on getting me investment options, but did say that the administrator is Transamerica. I haven't heard much about Transamerica on here, so I think I will take my chances with roughly $5k in VBTLX (to allow for bumping to admiral shares) and then the remainder to VTSAX, with ER of 0.06% and 0.05% respectively. I'd rather move it now, invest it and know the fees I am paying, rather than wait a year and then realize I have terrible options.
