Going to be blunt here, OP: it sounds like you’re living a lifestyle you can’t afford, but you don’t want to give it up. Do you really want to stretch yourselves even thinner by taking on more work, leaving even less time for you / your family?
I just see a long road ahead of stress, no time, working to live, sleepless nights etc. etc. but for what? A mythical lifestyle that you can’t actually enjoy, house that you can’t appreciate because you’ve got zero time. Family time that will be squeezed and juggled between all your other commitments.
For a lot of families I get that there is no choice. They cannot ‘downsize’. But you do. You can move to a smaller place, have a manageable mortgage, not worry about all the ‘what ifs’, and enjoy your life with what you HAVE.
I know so many families that are living on the edge. But these are not poor families, they have 2 cars, 4 bedroom houses, kids in private schools, but the stress from needing to keep all the plates spinning in order to afford this life, plus the worry of one of these plates dropping, is bringing these parents to their knees. But they don’t want to give up their lifestyle 🤷♀️
I think you need to take a hard look at your future, and realistically consider whether chasing more money via 2nd jobs to maintain a lifestyle that is just within your reach, is going to give you a life you actually want to live.
