Mortgage Free Mini-Goals

So, I've decided that I want to make a concerted effort to reducing our mortgage so that we finish our term well before the initial end date of April 2041. Unfortunately, I haven't quite set a fixed date in mind I just know that I want to pay it off early.

A bit of backstory for you all. My husband and I bought our first home together in April 2011. We initially had a mortgage for £108K. 2 years later when our fixed term came to an end we wanted to free up some money so that we could do some renovations on the house - extend the bathroom and convert the garage. We had the house revalued as £155K which allowed us to remortgage for £116K, giving us £10K for the renovations.

Life tootled on and I fixed out mortgage again at the end of the 2 year fixed period in April 2015 for 5 years. Annoyingly, we were just over the 75% LTV ratio when I remortgaged and within a few months we had dropped below it and could have got a cheaper rate and saved ourselves about £100 a month. But, I didn't know this at the time and hindsight is 20/20.

After our wedding last year DH's dad came along one day out of the blue and said he wanted to give DH an advance on his inheritance. Well, not just an advance but his actual inheritance early. To the tune of £100K!! :eek::eek: This actually rendered me speechless. Not something that happens very often.
As our mortgage was over this amount we decided not to put it all down onto the mortgage. Whether this was the right or wrong thing to do...well, people will have their own opinions. We decided to pay off our debts and put £10K down as a lump sum on the mortgage and invest/save the rest.
Oh and we both took £1000 each to do what we wish with. He spent his on a titanium frame and built a new road bike. I invested some of mine in Funding Circle, bought a new iPhone after buying myself out of my mobile contract and have the rest in a savings account. This is why I'm in charge of the household finances :rotfl:

Anyway....we now have a mortgage below £100K and when the statement came through at the end of December I was so excited! This seemed to me like a massive milestone and it got me thinking.
How much more could I do? How much money could I get out of my husband each month without him complaining too much? Where can I squeeze some money and put it towards the mortgage and bring it down? The fact that we shaved off nearly 5 years on the length of the term really excited me. How much more could I take off if we made regular over-payments?
Unfortunately we can only make lump-sum over-payments of £500+ on our mortgage. So, my plan is to save the money up and make either one or two lump-sum payments each year. This year I want to pay a minimum of £1,000 extra.

I've also just realised that this post is loooong and quite possibly very boring to you all. So, for now I will leave it at this and keep updating as I go along. Also, my cat has decided to sit on my arm as I'm typing and this isn't particularly conducive to typing.
So, hopefully I'll get a few followers on this journey of mine. If not, at least I've got somewhere for me to put my random and not-so-random ramblings.
