March 2009 NSP1 - $7.1 million Funds can be used to purchase foreclosed

properties Rehabilitate those properties Sell or lease those properties to eligible

families.

The policy guidelines are established by the County and /or City Commission

Those guidelines authorize the Director toenter into loan agreements with nonprofitagencies to purchase homes without goingback to the commission on each purchase

OHCD establishes the rehabilitation standards for the program

OHCD identifies the home Nonprofit partners have the ability to

purchase or decline each home The purchase price is at least 1% less than the

appraised value of the home OHCD lends the nonprofits the funds to

purchase the home and the repairs at a 0%interest rate

Nonprofit partners & OHCD jointly determinethe repairs that will be made

Nonprofit partners hire the contractor andapprove all payments

OHCD pays the contractor

Nonprofits identify the buyer The buyer obtains a first mortgage from a

conventional lender The sales price is the lower of the purchase

price plus improvements or the appraisedprice after repairs

OHCD provides the subsidy to make thehome purchase price affordable

Are our programsproviding energysavings?

Worked with the Building America Partnership for Improved Residential Construction todetermine our effectiveness ◦ 7 homes surveyed ◦ 117 Average HERS before rehabilitation ◦ 82 Average HERS after rehabilitation ◦ 30% average reduction in HERS score ◦ $399.29 annual cost savings

NSP2 was a competitive program Points were awarded for enhanced energy

efficiency. ◦ Energy Star appliances ◦ Water sense fixtures

1 of 56 communities receiving funding $23 million

Worked with the Building America Partnership for Improved Residential Construction todetermine our effectiveness ◦ 9 homes surveyed ◦ 131 Average HERS before rehabilitation ◦ 71 Average HERS after rehabilitation ◦ 54% average reduction in HERS score ◦ $750.66 annual cost savings
