Planners, Signs and A Community's Economic Well Being (Powerpoint) - Rick Bass
In a 1995 case in Decatur, Georgia, a Days Inn was allowed to use an electronic message center for four years that was actually situated on a third party's property. Property ownership changes occurred, so a payment needed to be determined. Three approaches were used: comparable sales, income and cost.
For the "comparison" method, the sign was compared to a billboard, Based on outdoor-advertising prices, for the 49 months, the price was calculated to be approximately $1.6 million.
The "income" approach examines Days Inn's income for the same time period: $8.4 million. The percentage of this attributable to the sign was calculated at 25%, which made it $2.1 million. Because half of the guests already had reservations (which meant the sign didn't draw them in), the figure was reduced to $1.050 million. Adding a 10% for interest earned, the final figure became $1.2 million.
The "cost" approach considers how else the property could be used. based on 238 units, the value of each motel room was set at $31,765. If they were all converted to apartments, their value would be $25,000 each. The value difference, $6765, multiplied by 238, becomes approximately $1.6 million. The full story, with detailed calculations, appeared in the April 1999 issue of Signs of the Times magazine.
