A 31 percent increase in value is a pretty good sign that the suburban apartment market is hot! Taylor Johnson client Prime Property Investors (PPI) was thrilled with its recent sale of a 224-unit multifamily property in north suburban Lake Bluff for almost 31 percent more than it paid for the complex less than two years ago. PPI credits the increase to higher occupancies at communities, higher rents, and increased value from rehabbing units and enhancing curb appeal.
