Tenant Moved out Prior to Lease End Date

I am currently house hacking a single family home and had a signed lease agreement with a tenant. The tenant had been staying in my house for a few months now. But, I recently found out that he just got up and left months before his lease term ended. He left behind the keys and took some of his personal belongings with him. I've tried to communicate with him as he still has 3 months left per the signed lease agreement, but no answer. 

What approach should I take here since I am now missing out on 3 month's worth of rent that I was expecting according to our lease agreement? Is there any way that I can report this to the credit bureaus and have this broken lease shown on his credit history? Any way I can enforce the lease so he pays me back the rest of the lease term? 

Any and all thoughts on how to handle would be greatly appreciated, thanks!
