I'm in the process of selling my house in NJ. Currently, the house is unoccupied (we've moved out of state). We have an accepted offer on the house. However, the potential buyers have entered the house 2-3 times without their agent. The agent either provided them the code to the lockbox, or let them in and left. To be fair, they weren't being malicious (they wanted to take measurements), but I wanted to know if this is legal. While their intentions weren't necessarily bad, I find this extremely annoying and unprofessional. I just want to know what the potential fallback would be if something would come up because of this.
