Moving to northern Ireland

I currently live in the UK with my partner,three dogs and a five foot fish tank.

We decided we wanted to move house a year ago as my partner is an asthmatic and he breathes easier in the countryside. I am hoping that we can find a decent rural/semi rural detached house/bungalow with outbuildings and a good plot of land.

I will have to commute back to my job in England unless l find work more locally.

We found even with a decent amount of equity in our house we have now that we can't find what we want in the UK unless we have a huge mortgage.something l don't really want now.
A lot of the places we see even on our limited budget would mean us being mortgage free and we don't know if we will buy a doer upper or a walk in ready to go house yet.

Any help or tips would be so useful and gratefully received
