Facing the prospect of a £600 hike in mortgage payments in July next year if interest rates/mortgage rates don't come down. Can't extend term due to age of partner. Both full time and earning full potential and good joint salary/ no childcare costs or school fees but cannot see a way of cutting anything more from monthly outgoings as we are not big spenders except on high housing cost to be in area for good schools and close to work. Interest only mortgage for 2 years would help stave off the inevitable but would mean a big (I think?) jump in repayments when switching back to repayment. Anything else we can do. Grateful for any thoughts, ideas or avenues I haven't explored. Thank you!
