You have decided to buy a small apartment building for $100,000 near a local college. You used $10,000 as a down payment and obtained a mortgage from a local bank for the remaining $90,000. The annual mortgage payment to the bank is $11,500. You expect that the annual maintenance on the building and grounds will be $14,500. There are four apartments (two bedrooms each) in the building that can be rented. Assuming 100% occupancy all year, how much rent per month must you charge in order to break even, such that your revenue equals your expenses each month. (Enter your answer as a number without the dollar sign.)
