(a) The interest rate on a mortgage loan originated or purchased in whole or in part under AS 18.56.420 for small community housing or multi-family housing under AS 18.56.580 is one percent less than the interest rate, as determined under AS 18.56.098(f)(1) - (4), on a mortgage loan purchased under AS 18.56.098(a) from the proceeds of the most recent applicable issue of taxable bonds before the origination or purchase of the mortgage loan originated or purchased under AS 18.56.420. However, the interest rate on that portion of a loan that exceeds $250,000 is the same as the interest rate determined under AS 18.56.098(f)(1) - (4).
(b) Notwithstanding the requirements of (a) of this section, if there has not been an applicable issue of taxable bonds issued within six months before the origination or purchase of a loan under this section, the corporation may estimate the interest rate that an issue of taxable bonds would bear.
