Fannie Mae announced HomeStyle Energy mortgage program last year, to help borrowers finance energy and water upgrades to make their home more energy efficient when buying or refinancing a home. The loan makes buyer-owners eligible to receive up to 15% of the as-completed appraised value of the home/condo to use for energy efficient upgrades. An “energy report” prepared by a local qualified energy assessor to verify the upgrades is required. Without a report, borrowers can still finance up to $3,500 in water efficiency improvements.
