Our home is our main pension vehicle. Currently property worth 1m have �160K left on mortgage in home counties - thinking of selling up and downsizing to clear mortgage so that I can be a SAHM to 4 kids thru tricky teenage years and exams - also worried about potential interest rate rises......but would we miss out financially in the long term to any future property price rises? No sure how the trade off of mortage interest vs price rise on 1m house vs price increase on 750k hs? Other option is that we use the move to buy family house for 450 and then a buy to let with the rest of the equity....what should we do for financial security?
