(1) The real and personal property owned or used by a nonprofit entity in providing rental housing for ((very low-income))qualifying households or used to provide space for the placement of a mobile home for a ((very low-income))qualifying household within a mobile home park is exempt from taxation if:

(2) If less than seventy-five percent of the occupied dwelling units within the rental housing or lots in the mobile home park are occupied by ((very low-income))qualifying households, the rental housing or mobile home park is eligible for a partial exemption on the real property and a total exemption of the housing's or park's personal property as follows:

(b) The amount of exemption must be calculated by multiplying the assessed value of the property reasonably necessary to provide the rental housing or to operate the mobile home park by a fraction. The numerator of the fraction is the number of dwelling units or lots occupied by ((very low-income))qualifying households as of December 31st of the first assessment year in which the rental housing or mobile home park becomes operational or on January 1st of each subsequent assessment year for which the exemption is claimed. The denominator of the fraction is the total number of dwelling units or lots occupied as of December 31st of the first assessment year the rental housing or mobile home park becomes operational and January 1st of each subsequent assessment year for which exemption is claimed.

(3) If a currently exempt rental housing unit ((in a facility with ten units or fewer)) or mobile home lot in a mobile home park ((with ten lots or fewer)) was occupied by a ((very low-income))qualifying household at the time the exemption was granted and the income of the household subsequently rises above ((fifty percent of the median income))the threshold set in subsection (7)(e) of this section but remains at or below eighty percent of the median income, the exemption will continue as long as the housing continues to meet the certification requirements ((of a very low-income housing program)) listed in subsection (1) of this section. For purposes of this section, median income, as most recently determined by the federal department of housing and urban development for the county in which the rental housing or mobile home park is located, shall be adjusted for family size. However, if a dwelling unit or a lot becomes vacant and is subsequently rerented, the income of the new household must be at or below ((fifty percent of the median income adjusted for family size as most recently determined by the federal department of housing and urban development for the county in which the rental housing or mobile home park is located))the threshold set in subsection (7)(e) of this section to remain exempt from property tax.

(4) If at the time of initial application the property is unoccupied, or subsequent to the initial application the property is unoccupied because of renovations, and the property is not currently being used for the exempt purpose authorized by this section but will be used for the exempt purpose within two assessment years, the property shall be eligible for a property tax exemption for the assessment year in which the claim for exemption is submitted under the following conditions:

(a) A commitment for financing to acquire, construct, renovate, or otherwise convert the property to provide housing for ((very low-income))qualifying households has been obtained, in whole or in part, by the nonprofit entity claiming the exemption from one or more of the sources listed in subsection (1)(c) of this section;

(6) The nonprofit entity qualifying for a property tax exemption under this section may agree to make payments to the city, county, or other political subdivision for improvements, services, and facilities furnished by the city, county, or political subdivision for the benefit of the rental housing. However, these payments shall not exceed the amount last levied as the annual tax of the city, county, or political subdivision upon the property prior to exemption.

(a) "Group home" means a single-family dwelling financed, in whole or in part, by one or more of the sources listed in subsection (1)(c) of this section.

(c) "Occupied dwelling unit" means a living unit that is occupied by an individual or household as of December 31st of the first assessment year the rental housing becomes operational or is occupied by an individual or household on January 1st of each subsequent assessment year in which the claim for exemption is submitted.

(e)(i) "((Very low-income))Qualifying household" means a single person, family, or unrelated persons living together whose income is at or below fifty percent of the median income adjusted for family size as most recently determined by the federal department of housing and urban development for the county in which the rental housing or mobile home park is located and in effect as of January 1st of the year the application for exemption is submitted; ((and))
