Contemplating 205K mortgage for 25 years (I'm 38, DP40) to buy family house for 355. 5 year fix so monthly payments just under 900. Our monthly net income will be 3,000. I'm only working 2 days a week and in 3 years will probably do full time. I'm a teacher. We are moving north out of London and mortgage is same as current outgoing in a shared ownership property so part mortgage, part rent. It's just overall amount we are borrowing will have doubled and back up to 25 year loan from 18 remaining on current one. Does that sound do-able? I'm risk averse but DP confident it's fine!
