Thanks Brendan for your reply.
Meeting bank end of Aug to do formal application, have met informally before and have been told we could have more than 70k but we don't need more as have savings plus profit from house sale. I'm not 100% sure of interest rate, we are actually moving from ROI to NI so borrowing from Ulster bank in NI. House when built will be worth approx 275k.
Am I wrong to borrow over 10yrs instead of a longer term? I thought it would mean we paid less interest doing it over shorter term. Would I pay higher interest rate by borrowing over a shorter term?
Have about 3k savings with credit union.
Going back to original query, would it make more financial sense to clear CU loan and borrow more in mortgage?
Thanks for your help
