Capital gains tax is a tax on the profit when you sell or dispose of something (such as a property) that has increased in value. It is the increase in the value of the property that will be taxed.
Income tax is a tax you pay on your income above the personal allowance (if you are eligible for the same). You do not have to pay tax on all types of income - for more information, please refer to: [Income Tax: introduction](https://www.gov.uk/income-tax).
You should review your personal tax situation and the implications of owning the property with a tax specialist.
