Am I bound by a previous owner's property management agreement?

[Alexander V.]

I'm not asking about what property managers write into their contracts. I've seen entire wish lists embedded into them. I realize that it is fairly common for property managers write in their contracts that the agreement survives sale. Assume that in this situation the property manager has included such a "survives sale" clause. Considering the fact that I never signed or agreed to anything and was never made aware of any obligations, does a clause claiming that the manager's rights "survive sale" have any legal grounds, or is this an unenforceable wish-list item that they throw in and hope it isn't challenged?
