Landlord charging me $300 to paint apartment after moving out....?

Paint is wear and tear after 2 years in ANY residence. She cannot charge you to repaint after 7 years. Tell her you will be in contact with a lawyer, and she will back off.

"The paint is your basic flat paint "

Flat paint typically needs repainting at least every 5 yeas. In MA, the housing authorities that govern the Section 8 program require the landlord to repaint every 5 years.

If all you did was use Kilz (with a Z) to cover the crayon marks (flat paint cannot easily be cleaned, thus the need to repaint so often)

"There were crayon marks on the walls, but I went over those with kills (sic)" it's Kilz with a "Z".

You should have made the landlord do the priming and repainting. You should have also made sure, in writing, that the landlord knew before you moved in.

I doubt it would hold up in court, but you never know for sure. It depends on the judge who hears these cases in your area.

If you changed the color the wall was when you first moved in will the kilts and it wasn't approved by your landlord then you do have to reimburse them for the painting they'll have to do.

Always approve work done with your landlord before doing it to avoid lawsuits and other legal matters!
