Bill was thinking of purchasing an apartment building. He wanted a 10% return on his investment and asked to see the books for this building. There are four apartments on each floor of the three-story building. The rent for an apartment on the first floor is $400 a month, and each floor's rent increases $50 per month, per apartment. Bill noticed a loss of rent through vacancy and collection losses of 8%, and when he figured the operating expenses, they averaged $610 a month. With all of this information, what is the most that Bill should pay for this building (round your answer to the nearest thousandth).
