It depends on your settings.
But is your home IP rotating or fixed? Check if your ISP rotates IPs regularly or on router restart.
If your IP rotate regularly, try to identify how long an IP stays active and adjust your accounts' actions in such a way so that each account will be active on the newly allocated IP address.
But, if your provider allocates a new IP on router restart, see if you can do something to restart the router/reboot the router just before an account is about to do some actions.
Generally, from an IP perspective, you'll want each account to be isolated from the other accounts.
