Suspicious vehicles near house under renovation

Caller advised he was there earlier working on remodeling the house.

As I was probably was there, there was several vehicles that pulled up and drove slow like they were looking at it, watching it.

As I, since he's left, he's had a neighbor call back.

Advising there was another car pulled up in the drive, turned around, but was driving slow like they were looking at it.He was just wanting to know if somebody could patrol.

He's got a lot of tools and stuff inside the house.
