Assuming you sold the property in December 2015, the first £11,100 of the gain will be tax free due to the annual CGT exemption. That leaves a net taxable gain of £58,900.
There are two rates of Capital Gains Tax, 18% and 28%. The rate or combination of rates that you will pay will be dependent on the level of your income in 2015/16. The most that can be taxed at 18% is £31,865. That will be reduced by £1 for every £1 of income you had in the 2015/16 tax year over £10,600. Therefore, your CGT liability will be somewhere between £13,305.50 (£31,865 @ 18% + £27,035 @ 28%) and £16,492.00 (28%).
I hope this helps but let me know if you have any further questions.
