I know it sounds small but is $50 worth it if you end up repainting when you are turning the unit anyway?

Makes repainting and touchups easier on all your units in the future.  

But the damage caused by hanging them (namely puddying the holes and touch up paint, or repainting walls if touching up doesn't work) will come out of their deposit. 

Do they think im repainting it with lead paint?

Also, I'm looking to re-paint most of the walls and kitchen cabinetry as the previous owner chose some colors that I don't necessarily agree with :). 

Once closed, we repainted the property, fixed plumbing and other odds and ends.

Put new PEX supply lines in, repainted everything, rebuilt some windows and repaired others.

The child that lived there wrote on a couple walls so the family room needed repaint, they never opened windows while showering ruining the finish on the cabinets and causing mold problems ruining the bathroom paint.This is an old updated 1940 home with no exhaust fans in the bath or kitchen so common since says  a window needs to be open when showering or cooking nut they were not.I documented everything with pictures and I have a letter from the flooring company stating what they saw.

The house had several floor joists and trusses in the attic that were cut through in order to run venting and pipes that needed to be shored up, some rotted subflooring that was discovered in the bathroom, some drywall needed to be replaced, the whole house was repainted, added a water softener due to the hard water from the well leading to discoloration of the tub, and upgraded the fixtures to make it look nicer.

In return I can help out for free ofcourse with many things such as landscaping around the property, repainting vacant units before new tenants move in, showing vacant units to possible new tenants, and many other things.
