Great topic Beth Anne,
Property Management is definately relational in terms of you are always going to be dealing with people every day in every arena.From tenants, to tradespeople, to contractors, to inspectors, to accountants and lawyers.
Navigating the relational aspect will be what you make of it, you have to decide upfront how you wish to treat these people? what sort of power do you wish to exert on them? From experience and from on-going learning i've discovered its the referent power that would grant you success in managing these relationship. Yes you may have legitmate or expert power but those won't sustain or nurture the relationship on the long haul.
Seek first to understand, than to be understood. You have to value people !
Just my thoughts
