SECTION 2. BACKGROUND

.01 Section 103(a) provides that, except as provided in § 103(b), gross income does not include interest on any state or local bond. Section 103(b)(1) provides that § 103(a) shall not apply to any private activity bond that is not a qualified bond (within the meaning of § 141). Section 141(e) provides that the term “qualified bond” includes any private activity bond that (1) is a qualified mortgage bond, (2) meets the applicable volume cap requirements under § 146, and (3) meets the applicable requirements under § 147.

.02 Section 143(a)(1) provides that the term “qualified mortgage bond” means a bond that is issued as part of a “qualified

mortgage issue”. Section 143(a)(2)(A) provides that the term “qualified mortgage issue” means an issue of one or more bonds by a state or political subdivision thereof, but only if (i) all proceeds of the issue (exclusive of issuance costs and a reasonably required reserve) are to be used to finance owner-occupied residences; (ii) the issue meets the requirements of subsections (c), (d), (e), (f), (g), (h), (i), and (m)(7) of § 143; (iii) the issue does not meet the private business tests of paragraphs (1) and (2) of § 141(b); and (iv) with respect to amounts received more than 10 years after the date of issuance, repayments of $250,000 or more of principal on financing provided by the issue are used not later than the close of the first semi-annual period beginning after the date the prepayment (or complete repayment) is received to redeem bonds that are part of the issue.

.03 Section 143(f) imposes eligibility requirements concerning the maximum income of mortgagors for whom financing may be provided by qualified mortgage bonds. Section 25(c)(2)(A)(iii)(IV) provides that recipients of mortgage credit certificates must meet the income requirements of § 143(f). Generally, under §§ 143(f)(1) and 25(c)(2)(A)(iii)(IV), these income requirements are met only if all owner-financing under a qualified mortgage bond and all certified indebtedness amounts under a mortgage credit certificate program are provided to mortgagors whose family income is 115 percent
