Plus I don ' t think the sole matyr is gonna hand feed us the information <| sep |> The problem the comment you ' re replying brings up advancing rotor breaking the sound barrier to can ' t be solved by coaxial rotors . <| sep |> It ' s the same logic . Security deposit B doesn ' t want to shouldn ' t have to be responsible for a new tenant trashing the place after she leaves , and she doesn ' t want to shouldn ' t have to wait yearsdecadescenturies until the chain of tenants ends to get her security deposit back . Last month ' s rent B doesn ' t want to shouldn ' t have to be responsible for a new tenant failing to pay rent and getting evicted , and she doesn ' t want to shouldn ' t have to wait yearsdecadescenturies until the chain of tenants ends to get her last month ' s rent back . Even if you think the security deposit thing is sketchy for some reason , there ' s definitely no way B should be responsible for paying your last month ' s rent . That isn ' t even something B would get back at the end of the tenancy you just won ' t have to write a check that month . Regarding the security deposit , if you really want to be careful , you can ask A and B if they took photos when they moved in always a good precaution ! , and if so , you could inherit those as your proof of the apartment ' s original condition . Compare the photos against the current state of the apartment , and you can guess how much of the security deposit would currently deserve to be refunded , and potentially negotiate with B based on what you see . In general , though , the new tenant would compensate the old tenant for both , and just make sure the landlord knows that happened for when it comes time for the security deposit to be returned .
