Doubt they will give you more than the property value as a mortgage, but should give you a personal loan for the furnishings (as long as you can repay of course).
I did hear that BoI were giving 100% + mortgages to certain borrowers, but this was 'thid hand' type of story.
Shop around though-ptsb aren't necessarily the cheapest for personal loans. For €10k, I'd give Tesco a look.
As an aside, your fairly highly leveraged, 100% mortgage, and furnishings also being paid for by debt (do you have a car loan as well?), maybe it's none of my business, but do you have any savings?
