If you are considering purchasing a home within the City of Atlanta limits, you might benefit from a downpayment assistance program from Invest Atlanta.
This program offers a 5% downpayment grant for owner-occupied homes at a purchase price below approximately $375,000.
Please see the link below regarding all the details.  At this time, Epic Development has several new homes that qualify for this incentive, including the homes at Riverside Walk, Francis Avenue, and some at Parkside Overlook.
