Thanks for your question - I am Sam and I am one of the Uk tax experts.
THis sale will give rie to capital gains in your daughters name, as
1) the property was placed in her name and
2) It has never been your main residence.
The gain will be established as the sale price less than purchase price, this forms the initial gain, From this initial gain she can then deduct the costs to buy and sell (such as legal and estate agent fees, if in her name) and the costs for any major capital improvements )again these muct be in her name) - then with any gain left over, the first £11,000 will be exempt as this is her annual exemption allowance, and any rmining gain will be liable to capital gains tx.
Plus as you wish to claw the money bck, she will then be considered for Inheritance tax, as she is, in essence "gifting" the money back to you, so she too, must allow 7 years to l;apse so that this is not considered for Inheritance tax purposes.
Let me know if you have anything you wish me to expand on, asthis is just th gist of the situation, and I am more than happy to expand on any elements of my response.
