275k mortgage 20 year target

danfreestone

Myself and my wife are buying a new house in March at 275k with a 2.45% interest rate over 30 years we will be paying £1070 per month.

We are looking to overpay by at-least £500 per month, through my work i can save £500 a month with SAYE which i then can buy shares or get my £18,000 back every 3 years. The company i work for shares are very volatile last 3 year period i made £10,000 profit.

As i can always get the £18,000 back am i right i thinking the risk of the shares not making profit is about £450.

Would i be wise to pay £500 a month directly off the mortgage or pay into the SAYE and every 3 years pay off a lump sum of £18,000 plus any profit.
