<prompt> Human: What is the best option for this? We just want a backup fund and something to save up for a future down payment on our next house. Would a CD be a good option for this or should we just look at regular savings accounts?  <response>: I would advise against having a joint account with someone who is not married to you. Either one of you will have full rights to all the money in the account, with no recourse if something bad happens. Set up individual savings accounts and use the money for the down payment once youre married.
