Housing Groups are calling for purchase and renovation of 7,500 homes in metro Atlanta over next five years to help rebuild Atlanta neighborhoods in the wake of the foreclosure crisis.  Achieving that would create jobs, help fill neighborhoods with homeowners and increase property values - without the use of local tax dollars.   Committed to Communities is joining Atlanta Neighborhood Development Partnership (ANDP) and Residents for Resources and Communities (RRC) along with Invest Atlanta and the Lifecycle Building Center to offer a two-day educational event in the Adair Park neighborhood concerning purchase and renovation.  The most common way to purchase and rehab homes is through what are known as 203(k) loans, guaranteed by the federal government and known by their HUD designation.  With one mortgage, buyers can buy the home and obtain financing for renovations.  Homebuyers in the City of Atlanta can use NeighborhoodLIFT money for purchase and rehab with up to $15,000 available for each home and more than $2 million still available.
