Every industry has a private language. Ours just happens to involve a pool gate, a package room and a maintenance ticket that has been open since Tuesday.

Here are ten things that need no explanation to anyone who has run a community — and complete explanation to everyone else.

1. The 4:55pm phone call

Nothing good has ever come from a call that arrives five minutes before close. It is never a question about office hours.

2. The package room as a moral test

You can tell a lot about a community from how its package room looks in December.

3. The tour that ends in a different unit

The prospect asks to see one more floor plan. You know exactly where this is going, and you are already reaching for the keys.

4. Nobody knows what you do

Your family thinks you show apartments. Your friends think you collect rent. You actually run a small business with a payroll, a budget, a compliance file and a maintenance department.

5. The difference between a resident problem and a building problem

Half the skill of the job is hearing the second thing behind the first thing.

6. Weekend brain

You have not fully relaxed on a Saturday in years. Somewhere in the back of your mind, a water heater is deciding something.

7. The renewal conversation

It is not a negotiation. It is a relationship interview with a number attached.

8. Your maintenance team is the whole thing

Every good month you have ever had was built by people whose names are not on the marketing.

9. The pizza party problem

You have watched leadership solve a morale problem with catering more than once. You have opinions about it.

10. You still like it

After all of that — the calls, the gates, the Tuesday ticket — most people who do this job well will tell you they genuinely like it. That is the part outsiders find hardest to believe.
