If he was short tripping his mileage, then it may be past due for an oil change, but since you are the new owner, now YOU establish the OCI you want to have based on YOUR driving scenarios.
However I dispute the idea that he didn't put much mileage on it if it has been 7K in less than a year. That may not be an average mileage but is far from low, and yet if all he did was go back and forth to work, possibly it wasn't short tripped at all to get 7K/yr.
If you want to do it yearly, sure now is a fine time. It won't hurt to change oil every day, just waste oil and time.
You're close enough that you might as well change it when that is convenient.
