Apartment saturated in pot smoke

[Scott Harlow]

I bought my first 4 unit last month. I have given a month-to-month tenant notice that I will not be renewing his lease. His apartment is saturated with pot smoke. I'm assuming the apartment will need to be wiped down top to bottom to remove the odor. The apartment does not have carpet or fabric curtains, so that's a plus. Do you think I will need to repaint? I'm trying to get an idea of what should be held from his security deposit. Thanks!
