“Commercial real estate prices have been rising steadily in the Sandida Heights

neighborhood for several years, while the prices in the adjacent neighborhood of Palm Grove have remained the same. It seems obvious, then, that a retail space in Sandida Heights must now be much more expensive than a similar space in Palm Grove, which was not the case several years ago. So, it appears that retail spaces in Sandida Heights are now overpriced relative to those in Palm Grove. Therefore, it would be in our financial interest to purchase a retail space in Palm Grove rather than in Sandida Heights.”
