Selling a property that still has tenants

[Account Closed]

Hello! My name is Thomas Pascarella and I'm looking to sell a property that I previously house hacked but am now using as a rental property. My tenants are leased up until the end of February and my agent says it can't be listed until the property is vacant to schedule showings. 

I am curious as to how other investors handle selling properties that are leased. Do I wait until the lease expires to get the listing up and have it sit empty?
