100.—(1) Where—

(a) a cottage, plot or part of a plot held with a cottage, subject to and charged with the future payment of an annuity is either alienated, or is acquired by the housing authority to whom, before the acquisition, the annuity was required to be paid, or

(b) an annuity is redeemed under section 99 of this Act,

all the provisions of the Act of 1936, including the statutory conditions which but for this subsection would continue to apply in respect of the cottage, plot or part of a plot during the payment period shall, in case the cottage, plot or part of a plot is so acquired or the annuity, as respects the cottage, plot or part of a plot is redeemed in full, cease so to apply, or in any other case, cease so to apply to such extent as the housing authority may, by order, determine.

(2) In this section, “statutory conditions” and “payment period” have the same meanings as in section 17 of the Act of 1936.
