First Rental property- when to lower rent?

[Kyle Pierrehumbert]

Hey! So I just closed on my first rental property and have it posted on Zillow, it is in a desirable area and I priced it competitively when directly comparing it to other listings. It has been listed on Zillow for 4 days, I have a ton of views on the post, but only one contact and person interested.

It's making me ask myself the question- when should I lower the rent? I would prefer to have as low of a vacancy as possible but don't want to be too eager to drop the price. Looking for general guidance here.
