<prompt> Human: My younger brother is in college and looking to rent a 3br apartment with two other roommates. The realtorlandlord is requiring that each of the three roommates has a cosigner. However, the lease isnt separated by person, so legally, all tenants and all cosigners are responsible for the full value of the rent. Im concerned about a situation where one of the other roommates decides he wants to leave early and his parents would rather take the credit hit than pay rent; in that case, I would be legally responsible for the money.Is this normal in apartment rental situations? Who would ever be willing to cosign for their relativefriends roommates?  <response>: This is pretty normal - virtually every joint lease has every signor be fully responsible for the rent. It keeps the landlord from having to deal with roommate issues when theyre in the real estate business, not a personal dispute business.If you dont feel comfortable with it, I would advise you not to cosign for them.
