Hi JL77,
There are lenders out there that will provide a mortgage up to the age of 70...........
From the information you have provide it appears that your parents have been declined from the high street lenders. Is this correct?
If so, provided their income is adequate and there are no legal issues, there are certain lenders currently on the market that will provide you with this mortgage. (Start Mortgages & GE Mortgages)
But and its a big BUT they will charge over the bench mark for this mortgage approx 5%........
You must take into consideration what your parents monthly outgoings are per month and compared it to what these lenders can reduce it to (Remortage PDH consolidating all existing loans and mortgage with possibility of cash back)
Unfortunately you will have to pay legal fees approx 1095 euro...this will be taken out of the Loan amount.
Alternatively you could go on the mortgage with your parents and I assume the high street lenders will consider this option...
