Unless the property is a real basket case, Good Luck in getting those "sight unseen offers" !
Are you going to keep the address a secret too . . . . or will the Tenants have reason to call the Police when they detect people (Buyers and their Agents) frequently lurking around the exterior, looking, talking and taking pictures.
I think they'll resent the LandLord trying to do this more than if he simply came clean and told them, and also gave them an opportunity to buy it if they were interested.
In this society, they'll know what he's up to faster than he can imagine . . . . the speed of gossip is ultrafast; they probably already know.
Nobody's fooling anybody !
