We've gone through a bunch (including the Igloohome locks mentioned in the post) and landed on Yale's Assure line, specifically the YRD216 model with a physical keypad (not the touchscreen). Deployed in 100s of homes now (we're also property managers) with really no issue. We use Z-Wave to control but their modular system allows for Zigbee as well.
I would avoid the Schlage "Smart Deadbolt" model. At least when it comes to remote control they're pretty awful. (They're also hideous imo)
