im no expert at this, but as far as i know, if all 6 of you sign the lease, you are all liable.

yes, if one leaves, and the rest only pay "their parts," the credit or leasing history for all 6 of you will be fucked... not just his.

then again im no expert, but thats my personal experience take on it.

6 roommates dude? i hope theres at least a couple of girls.... sausage party ftl.
