I took out a 35 year mortgage in 2019, now down to 30 years thanks to some overpayments. I've always focused more on savings and have mainly put spare money in that because I'm the "what if" type of person who worries about not having most of my money there to use if I were to become unemployed etc. But now that this interest nightmare is happening I'm thinking, if my new job (starting next month) goes well I will give it six months to feel stable then throw a massive chunk of my savings at the mortgage - the amount I'm allowed to overpay per year. It will knock nearly 4 more years off and I'll still try to have a decent amount for an emergency new boiler or whatever in my savings... my savings account generates basically zero interest and according to Martin Lewis (in my situation) overpaying is best. I'm fixed until 2026 so ideally if possible I'll throw as much money at the mortgage as I can until then. But when I do come to remortgage in a few years, other than the outstanding amount being lower than expected how will I benefit from this? If at that point it's still gone up to 6% the monthly repayments will still be as extortionate as they would be if I'd not overpaid at all, is that right? Or not? Sorry if I'm being a bit dense I really don't understand all this grown up stuff!
