Meeting agent today for potential triplex, what questions to ask?

[Account Closed]

Today I am meeting with my agent for my first potential triplex purchase and would like some advice on what specifically I should ask the agent.

The triplex is currently vacant with notes on all three doors stating "the plumbing has been winterized as of 1-19-2017."

All advice is appreciated, as this will be my first purchase. If anyone needs more information about the property for a question I should bring up to the agent, please let me know. 

Thank you.
