Income from both Ireland and UK

Hi,

I am currently living in Ireland and travel across the border to Northern Ireland every day for work... As such, I am paying income tax/national insurance through the British tax system.

This year, I will be completing the build of an investment property which will be subsequently rented out.

As I will have income from both sides of the border, how will I pay tax...

1. Pay all tax liable through the UK tax system?
2. Pay income tax through UK and rental tax through Ireland?
3. Pay all tax liable through the Irish tax system?

Thanks in advance for your response.
