You're learning about the eviction process, tenant screening (never "word of mouth" again), the power of a lease WHEN not IF a neutral third party needs to be involved, tenant/landlord laws, and managing tenants who don't care about your business the way you do.

Can't say what's hardest, too many moving parts but take care of your tenants and build that goodwill, pays off in spades.
