Stamp Duty Land Tax

We split our time between home A and home B. Both are presently on the market and an offer has been accepted on B. Property A is likely to take a long time to sell. We aim ultimately to purchase property C and then live in C as our sole property. We have had an offer to purchase C accepted, and plan to purchase C simultaneously with selling B, but whilst A remains for sale. Q : when we purchase C (simultaneously with selling B, but whilst we still own - but are trying to sell - A) will we have to pay the second home rate of SDLT (i.e. currently +3%)? If so, will we be able to claim a refund of the additional SDLT paid when we finally sell property A?
