A modified gross lease can have many different meanings, but the full service gross is easier to quantify. The rate on a Full Service Gross (FSG) lease INCLUDES rent, taxes, cam, heat, water, electricity, and typically in-suite cleaning. There should not be a provision for increase in taxes, if FSG is truely FSG. You will still be required for your internet and telephone systems though.
Modified Gross (MG) is a mix of the above. Typically the rate includes Rent, taxes, Snow Plowing, grass cutting, and taxes. Usually you'll be responsible for utilities and increase in taxes.
Hope this helps!
