Property Management Contract Assignments Opportunity

[Andy Chen]

Hello all, can I have your advice. I have an opportunity of purchasing the contracts from a property management company. I have never done this before.
Two questions:
(1) Do you make official offer only after signing NDA and reviewing the contracts?
(2) What multiplier range on the management fee revenue is reasonable?

I feel the contract retention is unpredictable regardless how loyal the current clients are to the seller. Hence the risk to me is very high. Any suggestions or comments are welcome. 

Thank you
