* For the multifamily sector, eligible versions are determined for acquisition dates through 2026 because the applicable lookback clause in § 45L(c)(3) specifies the version in effect “three calendar years prior to the date the dwelling was acquired.” In contrast, because § 45L(c)(2) specifies a two-year lookback for the single-family and manufactured home sectors, the eligible versions applicable to 2026 acquisitions in those sectors will be determined on/after January 1, 2024.
