Hi there. I don't know the answer to your question - are any lenders out there who will give 90% mortgages to second time buyers - off the top of my head.
I know this isn't the information you were looking for, but why do you need a 90% mortgage?
15% of the €250,000 purchase price is 37,500. If you took EBS's 85% mortgage, you would still have €7,500 left from your savings. Your stamp duty is only €8,750, and if you are earning 95k a year, you'll save the €1,250 in no time. Your furniture is already bought. So why not just take EBS's 85%? You don't need any more.
