How can my mother transfer her property into mine and my brother’s name in the most taxefficient way possible?

Arthur Weller replies: 
If the value of her estate (as calculated for inheritance tax purposes (IHT)) is less than or equal to the amount of IHT nil rate band available to her, she is best advised to not make a lifetime transfer to you, but instead wait until she dies, and then transfer IHT and capital gains tax (CGT) free. If that is not the case, if full principal private residence relief from CGT is available on this property, she can transfer to you now without CGT to pay. If that is not the case, she could transfer in stages, over a number of tax years, so that the amount of gain triggered per tax year is equal to or less than the amount of the CGT annual exemption (£12,000 for 2019/2020).
