( 2 ) Appraisal formula. The participating jurisdiction may use an appraisal formula to determine fair return on investment and resale price based on the amount of market appreciation, if any, over the term of ownership. Under this method, the appraisals must be conducted by a State licensed or certified third-party appraiser. The amount of market appreciation over the term of ownership is determined by subtracting the appraised value at the time of initial purchase from the appraised value of the property at the time of resale. The fair return on a homeowner's investment under this formula is calculated by multiplying a clearly defined, publicly accessible standard or index by the amount of market appreciation over the term of homeownership.

( 3 ) Index formula. The participating jurisdiction may use an index formula to determine fair return on investment and resale price based on the change in value of a homeowner's investment over the term of ownership. Index formulas adjust the value of the homeowner's investment in proportion to changes in an index, such as the change in median household income. To determine the homeowner's fair return using this model, the sum of the property's original purchase price and the value of any capital improvements to the property is multiplied by the change in the specified index during the term of ownership. The formula may also depreciate the value of the capital improvements and may take into consideration any reduction in value due to property damage or delayed or deferred maintenance of the property condition.
