Yes. That's exactly what could happen and often does with roommate situations because the tenants are jointly and severally liable for the terms of the contract until all occupants satisfactorily surrender the rental to the owner.so by the same rational a roomate that moves out at the end of a lease is responsible for the lease if the other room mate stays and doesn't pay rent?
The whole idea of requiring a co-signer is that the co-signer's pockets ARE deeper and his/her credit better than those for whom he is a guarantor.lease ends, I give notice of not continuing with the contract, the property manager does not negotiate with the remaining tenants, how am I more responsible than a roomate that moved out in the same situation? besides my pockets being deeper?
Perhaps you didn't understand what you were guaranteeing when you signed the lease. It's simple. You guaranteed to pay if the tenants didn't.
By the way, you haven't answered the questions about the terms of the lease.
