1. A machine comprising a computer configured to display multiple computer screens on a monitor operably associated with the computer, the machine comprising: a first computer, operably associated with a monitor, which receives digital input data representing a first component of property and a second component of the property from at least one other computer, wherein the property is a fixed-income asset, wherein the first computer is program-controlled to manipulate the digital input data to generate one yield/discount rate for the first component and an other yield/discount rate for the second component and to display electronically the one yield/discount rate on the monitor in a first computer screen generated by the first computer and the other yield/discount rate on the monitor in one of the first computer screen and an other computer screen generated by the first computer, to perform a computation of one purchase price for the first component and an other computation of an other purchase price for the second component in consummating a sale and corresponding purchase of the first component to one buyer and a sale and corresponding purchase of the second component to an other buyer, wherein the computation of the one purchase price includes discounting cash flows reflecting the first component at the one yield/discount rate and the computation of the other purchase price for the second component includes discounting cash flows reflecting the second component at the other yield/discount rate, and to generate financial analysis output including one of the one yield/discount rate and the one purchase price, and which outputs the financial analysis output at an output device.
