Who is responsible me or previous landlord?

[Miguel Torres]

purchased a tenant occupied home, the tenant was moved in by previous landlord during the buying process which I was ok with. Long story short, the lease signed between the former landlord and tenant states that there should be a washer and dryer in the home which there is not. The tenant has asked me about this and I have tried to reach out to the previous management company with no luck. 

Who is on the hook for supplying the washer and dryer to the tenants myself or the previous landlord? RE agent says previous landlord but I just wanted a few more opinions on the matter. 

(All lease terms are the same from previous owner until the lease is up then I will write my own lease up for current/next tenant)
