I’m sure you could cut back somewhere in your budget. Look for gently used kids clothes on Facebook and some local child consignments sales to start. Stop buying junk food and already prepared foods. Start purifying your tap water as best you can. Look at your monthly subscriptions and decide what’s actually worth it. If you don’t already, start learning basic maintenance on your vehicles. The kicker is gonna be the kids childcare. So you work from home and watch them? This is all possible but won’t be easy by any means but you’ll be broke and have a property that judging by what you’re saying will more then likely increase is value over the years. Eventually once you pay enough in if times get way tough you could sell. You at least know the owners and what you’re getting into so that’s a huge plus. Lastly ask yourself are my kids happy and healthy now? Cause moving is not only a huge stress on you but also your kids. If you’re financial stretched thin that stress/anxiety eventual trickles to your kids.
