We have a fixed mortgage for 2 years and are both working full time at the moment. After the fixed rate, we want to move it to another fixed rate, does it matter if we only have 1 full time wage by then (we will stay with the same mortgage company just fix it up again)
If you are not increasing borrowing and staying with the same lender then probably it won't matter. The problem arises if you move lender and they will apply their rules to your income and may well not lend as much. Depends on how stretched you are in the first place.
