Steve Silver purchased a parking lot ten years ago for $100,000. He has earned an average annual net operating income of $14,000 and is now considering selling the parking lot. Manny Mumford likes the parking lot's location and initiates negotiation for its purchase. Silver points out that the city has recently increased parking fees at municipal lots and observes that fees can now be raised on this lot sufficiently to move the net operating income to about $20,000 annually. He notes that the $14,000 per year he has been earning represents a 14 percent per annum return on his investment. He thinks this is a good yield and states that Mumford can do equally well, based on the anticipated $20,000 per annum net operating income, by paying about $ 144,000 for the lot. Mumford retorts that Silver will have an assured rate of return once the lot is sold but that Mum ford will be taking a risk that the anticipated cash flow will not materialize. Therefore, says Mumford, she should earn a premium. She suggests an 18 percent yield and offers a price of about $111.000. Both parties earnestly state their desire to be fair and equitable in establishing a price for this property, but they are at odds as to how a price might best be determined. What do you suggest
