Gifting property and stamp duty reclaim

[CantDecide]

We purchased a new property as our main residence whilst trying to sell the existing one.

Sadly despite almost every property thread I have seen recently saying properties are flying off the shelves and people are having to pay overs, we haven’t managed to sell the old one.

Due to having the existing one we had to pay the higher level of stamp duty with the hope of selling the existing one and reclaiming it. We may continue to attempt to sell, but another option is to rent it and when our daughter reaches 18 (in 26 months) gift it to her and likely keep it rented. Can anyone confirm if we went down this route whether having gifted it our daughter (within 36 months or purchasing the new main residence) we can reclaim the additional stamp duty??

Thanks in advance.
