@OhioOhioOhio - have you called the bank? A lot of providers allow you to overpay 10% of the remaining balance per year without incurring any penalties.
You said you dont have a lot of money behind you. Personally, I would always try and have a savings buffer first before overpaying the mortgage. That way you have an easy access emergency fund in case you need it. I'm being nosey but do you have any other debts? If you do check the interest rates on them. If they interest rate is higher than interest on a savings account, it makes sense to pay the debt off first.
Also, with mortgage interest rates being so low, it might be worth sticking any extra money in a pension, as long term this is is likely to grow and give you better return.
Sorry if I'm preaching to the choir, I read a lot of forums and articles on the money saving expert website and it has been invaluable to me. Martin Lewis is really good and the articles are clearly written, plus the support and advice on the forums are really good too.
I put extra into my pension each month, but still OP my mortgage when I can. For me, paying it off quicker (hoping to be done by 50) means i can be more flexible with work. Even though I know I could her much better returns if I invest elsewhere. I want the security and peace of mind knowing no one can take my home away from me once its paid for.
Good luck, whatever you decide.
