Keys to a successful purchase and transition on multifamily

[Karen Cupp]

I am under contract to purchase my first multifamily. We are in the due diligence phase of the process.  What are some keys to this transition both operationally and tenent wise that I should include in agreement for a successful transition?  I am aware of things like making sure I get all of the deposits and keys but are there other key questions I should pose to the owner?
