I have interest only mortgage due for repayment and little hope of finding funds. old to remortgage. help?

Can somebody please give me some advice on the following. i have an interest only mortgage which was taken out several years ago and now has only a little while before capital is due. i k out this loan in order to pay off creditors but was only able to get a loan for five years because of my age. i have had the house on the market in the hope that it would sell quickly. alas this has not happened and time is marching on. any ideas please would be sincerely appreciated. thank you.
Answer
Chase the agents. re-approach anyone who viewed the house. reduce the price or offer cashback. chase the agents. again. ask them what they have done to match your property with potential buyers on their books. ask them what they have done to earn their fee. can you do a no sale, no fee agreement elsewhere as well? is your property online? did i mention chasing your agents?
