Selling a rental with tenants

[Benjamin Haberman]

I am selling off some of my portfolio that is fully rented (3 duplexes and 1 single). The tenants aren't being very responsive for showings. I don't really blame them. It's a pain. I would think investors (knowing it's rented) would be willing to preview the place during inspections, since it's strictly an investment property. Any recommendations on selling off rentals that are fully rented? Any advice would be much appreciated.
