They're drawing on my Cabinets!!!

[John Matthew Johnston]

My first rental is a B class SFR, Rent 1500/month. I put all new finishes and it LOOKED really nice. I went to do my first rental inspection after 5-6 months( while doing a walk through with an appraisal company to BRRR it) and the place is disgusting. They kids have drawn on the new white soft close cabinets with green marker and I counted at lease 8 other places they have been drawling on the walls. the floors have food and crumbs all over the place. empty mountain dew bottles and wrappers are all over the house. Dont get me started on the new stainless steel appliances that are covered in a layer of gooo!! The front porch is just covered in all kinds of **** like cloths and garbage. How do I document a written warning. An official letter of some sort. I want to warn them and give them a chance to rectify but im not sure they can make the change.
