Tenant took oven, left a new one!

[Lois S.]

SFH, long-term tenant vacated & left it very clean. Have not returned their deposit yet.

For some reason, tenant took our electric range that was installed less than 1 year ago, & replaced it with a new model. Never used, still has some tape in the oven.  They left me the paperwork to send the warranty in, but no receipt. Only a 1 yr warranty. 

The oven comes with a anti-tip bracket which was NOT installed.  I'll have to hire someone do the installation properly.

Has anyone had this happen before?   Any comments?
