Hi Brian K
We do not comment on scenarios. As you live abroad, your interest is treated as 'disregarded income' in the tax calculations.
Guidance on disregarded income can be found here HS300 Non-residents and investment income (2022)
The helpsheet explains how interest is taxable if your are not resident in the Uk for a tax year.
On your tax return, you would declare your rental income and expenses, bank interest and declare that you are not resident.
If you are still experiencing difficulty in this matte, you may wish to seek the advice of a financial adviser.
