Hi I don't know if anyone can advise us. My 19yr old son has arranged a house with 3 friends for his 2nd year at uni. I said I wouldact as guarantor that he would pay the rent but the guarantee they want me to sign has me responsible for damage during the tenancy & beyond. I'm a single parent on a lowish income & I've never met his friends. I'm sure they're all really nice people but if something goes wrong I can't pay for major damage. His father won't sign either. Any ideas?
