Yes, it is not your 傳統, it is the Chinese 傳統.
However, the Chinese 傳統 is:
禮金都係要6299比 and,
after get marry, all the income you and your husband earn are belongs to 99.
Do you follow all the Chinese 傳統? Or only follow partly which is adv. to the you/your parents?
Will 女家 parents give that flat for 男家 parents?
If yes, then 比八萬八禮金換間屋, 係99都lur飯應啦! (in 99's name)
If not, i.e. 99 should give 八萬八禮金 and get nothing........... (the flat is only in that girl's name).
In that case, the husband should give 八萬八禮金換間屋, not the 99.
