Contract left back doors open and I am out $2,000 in appliances

[Remington Lyman]

A contractor put in barn doors in my out-of-state client’s duplex that I am managing in Columbus, Ohio near The Ohio State University.I guess they left the back doors opened because when I went to do a tour today they were unlocked and 1 fridge and 2 stoves were missing.

I replaced the deadbolts in case they somehow got keys. I ordered replacement appliances from Lowes and they are coming in tomorrow. I am out $2,200.

What would you have done to prevent this?
