If you're looking at multifamily properties over 4 units, this is going to be a critical number to know as the banks derive the valuation of a property in part from the NOI (NOI/Cap Rate).The Cap Rate is going to be dictated by your local market for that particular asset class, so there's nothing you can do to control that, but you can control the NOI by increasing revenue (raise rent and additional income sources (parking, laundry, pet fees) and by decreasing operational expenses (spend less to actually operate the property).One of the biggest expenses you'll have on a property are the utilites.
