That's exactly how it looks. If everyone were to accept all the well-meaning advice (only 30% of net income, everything must be affordable with one salary), then we would probably have 50% more renters than homeowners in Germany and the homeowners we have would live in a very cheap house aka a wreck so that the installments wouldn’t be too high.
You’ll laugh, but we
do have 50% more renters than homeowners. According to the Federal Statistical Office, 28% of households can afford their own house. If you also include condominiums, that amounts to 46%, which means that 54% of households rent.
Still, I agree with you if you think that 30% of net income is calculated a bit too cautiously. I think the advice is up to 45% - the truth lies somewhere in between...
We are also thankful for the advice. But is it really the case that we only have 100-200 EUR left after all expenses and therefore truly live on the edge? I don’t think so. Sure, we don’t have 2000 EUR or more left per month either, but there is a buffer so that expenses for food and other things can also increase.
For example, I haven’t read a single time here (You have calculated the costs narrowly, but you still have XXX Euros left per month to cushion possible changes). It is almost as if the 700 EUR + shift bonuses are simply ignored, or put differently, if sometimes 1000 EUR after ALL expenses are not enough at the end of the month, well then who can still afford property nowadays. Probably only the top 10,000.
I would say your main problem is the outsourcing of all positions that can’t be booked under “everyday life.” In doing so, you lose sight of how large this item actually is and therefore cannot understand if someone at best attests you a “buffer” of 300 euros.
Calculate it yourself (I deliberately take low values):
You already mentioned daycare meals --> 50 euros/month
Once a year around the child (clothes, toys, car seat, etc.) for 120 euros --> 10 euros/month
Once a year one pair of pants each at 24 euros --> 4 euros/month
Once a year one set of tops each at 24 euros --> 4 euros/month
Once a year new underwear and socks at 12 euros each --> 2 euros/month
Once a year a barbecue party for a birthday at 96 euros --> 8 euros/month
Twice a year a good book/a CD (x2) at 15 euros each --> 5 euros/month
Every 2 years a vacation at the sea: 600 euros AI --> 25 euros/month
Every 2 years a new pair of shoes at 48 euros --> 2 euros/month
Every 5 years a new laptop/tablet/PC (x2) at 240 euros --> 8 euros/month
Every 5 years a new smartphone (x2) at 240 euros --> 8 euros/month
Every 7.5 years two sets of new tires at 280 euros each --> 6 euros/month
Every 10 years a new piece of furniture averaging 360 euros --> 3 euros/month
Every 10 years a new TV/projector at 480 euros --> 4 euros/month
Every 10 years a new dryer at 240 euros --> 2 euros/month
Every 10 years a new dishwasher at 240 euros --> 2 euros/month
Every 15 years a new car at 10,000 euros --> 56 euros/month
Every 15 years a new refrigerator at 480 euros --> 3 euros/month
Every 15 years a new washing machine at 480 euros --> 3 euros/month
Every 20 years a new stove at 480 euros --> 2 euros/month
That’s already 207 euros monthly so far. However, not one cent is included for the maintenance of the house and the mentioned things must also endure the given period without breaking.
Small things like a new light bulb (or even a lamp), new dishes, glasses, cutlery, pots and pans, PC peripherals, printer cartridges, printer paper (you can tell I let my gaze wander through the apartment, right?), cinema, eating out, zoo visit with the little one, a new plant for the apartment/garden, new bed linen, towels, windshield wipers for the car, hairdresser visits, co-pay at the dentist, the little one’s hobby, tools, decoration, etc., I have left out directly.
Now you have an income of 3800, of which 2400 remain every month (rent excluded), with which you want to cover an installment of 1200 plus 180 euros ancillary costs. That initially leaves you a calculated 1020 euros “buffer,” but all of this still has to be paid from that. Realistically, you really only have a “buffer” of maybe 300 euros.
And now you become unemployed and your actual net (including all allowances, etc.) is then, let’s say, 2000 euros. As a calculation basis, there is 67%. That’s then 1340 euros, i.e. 260 less than the net amount calculated here, ergo you are then short by 260 euros and it gets very tight if it even fit before.
The point is: It’s doable for you but in this constellation right on the edge. Any unforeseen difficulty can break your neck. If you want to bear the risk – go for it!
