It's like buying a Porsche, but then taking steel rims because there's no money left for aluminum ones.
I once rode along with someone, 7 Series BMW, putting regular gasoline in at the gas station, half full, and then wanted to tell me he'd top it up at home with super low-friction oil... of course. The stork brings the children... Equity: it was said he had 20k€ and she 10k€, and each would now save 500€ per month. That makes 54k€ in two years, according to the plan. Why they couldn't start saving earlier... they owe us no explanation about that. Maybe a second-chance education, student loan paid off, doctorate with half a position... to be continued. But if 700€ rent leaves 1000€ over... Adam Riese says that all goes into the house then. Ok, 800€ car lease is freed up, but then again two cars are needed, and even if you get them for half the price... 400€ per month remain disposable. The two have to think about whether that is enough for them. I have 500€ left over after paying what must be paid. From that, vacation still has to be managed, extra money that goes into hobbies, but basically also building reserves. It's actually too little for me, should be more (before starting the project, I calculated it looking much better), but two plans didn't go as expected and bam, I'm missing a few hundred euros every month...
