One developer’s fumble became another developer’s win in the Gold Coast this week. Chicago-based R2 Companies successfully completed a buyout of all 20 units at a condo building at 127 Maple Street last week after four years of negotiations, R2 Partner Zack Cupkovic confirmed. The total purchase came out to $4.7 million or about an average of $235,000 per unit, though individual condo purchases vary based on unit size and specifics.
