Storage Unit Purchase With Past Due Rents

[Shaun Moore]

Hi there. I am purchasing a storage unit facility. There are $2,500 of prepaid rents that the sellers are transferring to me. There is also $1,400 in past due rents that they want to deduct from the $2,500. The property has been in an Estate for a while and not properly managed. 

Is this a common arrangement? I feel like I should not have to acquire the debt, and at very least negotiate on it. 

Thanks in advance for your thoughts.
