Mortgage refinancing
First, check with your lender to see if the terms of the loan allow early payoff.  If you are able to payoff early without penalty, with the numbers you are posting, I would hesitate to refinance. This is simply because if you actually do pay 5k/month on this loan you will have it paid off so quickly that refinancing will probably not save you much money. Back-of-the-napkin math at 5k/month has you paying 60k pounds a year, which will payoff in about 5 years.  Even if you can afford 5k/month, I would recommend not paying extra on this debt ahead of other high-interest debt or saving in a tax-advantaged retirement account. If these other things are being taken care of, and you have liquid assets (cash) for emergencies, I would recommend paying off the mortgage without refinancing.
