The true question is what is the properties highest and best use. While prior performance is an indicator of future performance it is not the only factor. For example, a television repair shop on a corner does $50,000 in profit per year, so its value can be calculated as a multiple of it's earnings.
then there is a big announcement that a new factory is going in next door to the television repair shop. Is the best use of that location still a repair shop? Wouldn't a sandwich shop or a co0nvenience store be more valuable there? Would you sell it based on it performance as a repair shop, or would you sell it for its value as a sandwich shop?
The value in your property is in what can be built there and how profitable the new endeavor will be.
