<prompt> Human: Me and my roommates take turns paying the full rent amount. So every 3 months I pay a lump sum of about 2300. I was wondering whether it would be worth it to keep the amount in a CD or checking. For convenience I was thinking of just staying with my chase bank. 3 month CD was about .02 or about .01. Any other options I should consider?  <response>: A better option is having everyone pay 13 of the rent every month. Its as simple as set up a Paypal, Venmo, Dwolla, or whatever. Or writing a check takes all of 20 seconds. If theyre responsible adults, they shouldnt have a problem. If they do have a problem.. thats the first red flag.Relative to what you can gain a few dollars extra in interest, theres too much credit risk to hope the one roommate has the full amount on time. If youre interested in the math, I can break it out.But if you insist - Ally and Discover both have online savings accounts in the 0.75 - 1.0 APR range there are a few others Im sure, check
