Was searching for good rates and Alliant Credit Union (Chicago) does have excellent rates. Their JUMBO rate for 48-60 months is 3.057 (3.10 APR). Old institution which requires membership in area organizations in order to participate ($10 for membership).
I was trying to obtain ratings from Bauer Financial and for some reason could not find. Anyone out there that can be of aid? Interesting website: http://www.alliantcreditunion.org/
