I can do that. Our loan will be approximately €420,000 - €450,000. We contribute equity through the property worth about €130k. Net income is over €6,000 (both earn around €3,000). Both jobs are crisis-proof. Family planning is complete (1 child, 8 years old). And I am worried whether we will manage. This may be subjective. But our conditions are much better....
Of course, this is because I always have the family in mind. What if... Problems arise faster in families with financial difficulties, etc. Better happy in an apartment than turning over every penny in a house.
In general, one must also say, it depends a lot on the way of life and what else one wants or does. A family that wants to go on a ski vacation at least once a year and at least once a year spend two weeks all-inclusive by the sea in a somewhat more expensive area needs quite a few thousand euros more per year than a family for whom two weeks of vacation in a normal hotel or camping or whatever is enough/fun and that they are completely satisfied with. Going out to eat steak once or twice a month for €30 per steak or grilling it at home oneself – or other restaurant visits. Does one like to buy new clothes repeatedly that cost a lot or technology that one actually does not need for everyday life, or other expensive hobbies... Therefore, it is very important to realistically look at one’s own expenses beforehand, consider whether in the future one might want to spend more money on hobbies (in the sense of "I’ve never been on vacation before, but it has always been my dream to go every year for two weeks to a cool hotel"). Unforeseen circumstances (maybe in the future one will become a tech fan) should also be included in the calculation, as well as the fact that many things "always become more expensive." Prices sometimes rise more than one’s own salary. Expenses for possible repairs to the house or equipment must also be taken into account. Washing machine, stove, maybe a new sofa, new TV, etc. occur from time to time. But here the question is: Is a TV for €500 enough or do you want the latest technology for €2,000 or more, or do you take a middle way. Simply be honest with yourself when calculating and don’t sugarcoat things. Better to have more money at the end of the day than to no longer be happy in your free time because of the house.
Following this: statements like "€4,500 net is too little or enough" are always a question of "life attitude." Too many factors play a role. In the end, one must compare a real listing of one’s expenses per year with an income list. What is left then after all fixed costs and do these additional incomes cover unforeseen costs without having to give up anything for oneself in everyday life.
