Got pros and cons. If you go through your agent, then he will charge you when tenant wants to renew. But in this situation I will get the agent to kau tim all the small repairs, replacements, chase tenant for payment etc. I will just give instructions to agent and he will bill me the costs. This is good if the property is far away and you don't have the time to do it your self.

If you liaise direct with tenant, any renewal no need pay agent but tenant will kacau you to fix this fix that etc.
