Washer and dryer inclusion may get you an extra $25-$50 a month, but you'd have to check what your competitors are offering as many apartments offer in-home and/or on-site laundry.You can also consider LED lighting, pet rent, storage rental as other ways to add value and increase rental income.

There are probably better ways, but those are a couple I would try today if I were in your shoes.
