Financing for new construction: realistic or rather wishful thinking?

Hello, including additional costs, 50% of the income goes toward the house. Any buffers do not exist. Leave it be!

Good morning, thank you very much for the feedback.
When we look at the current situation, we have €4,750.00 income and €2,000.00 for housing costs + savings rates. That would be approximately 42%. Now, if we assume our salary rises to €5,250.00 and the house costs to €2,600.00, we would be at the mentioned 50%. Do those 8% make that much difference? We have currently been a bit lax and have not thought long about expenses for our standards, and therefore thought that the 8% with more caution would probably be manageable. For me, more hours would be added sooner or later anyway.
My husband and I each have a 13th salary, which would serve as an annual buffer, which I did not list. The additional costs include a €5,000 buffer, and additionally I had also included a "free buffer" of €5,000. Is that much too little? What would be more appropriate?

Multiply 5,000 net by 0.35, that is the pain threshold a bank uses, which makes 1,750 EUR. And even that comes from times before inflation... I would have said 1,500, I wouldn't do more.

Good morning, we have already calculated this with a bank and they would even give us a loan with a monthly burden of 2,500.00 €. Of course, that is not our plan! We already have 1,750.00 € from rent and saving for the house. I actually find 1,500.00 € relatively low at first glance.

It is mentioned as a rule of thumb to spend 1/3 of the net income as the installment. That doesn't always work with lower incomes. I also went over the third. I would advise you to look for something a size smaller. A townhouse, small plot already saves a lot.

Good morning, how much are you approximately over then? Unfortunately, very little to nothing is offered in this area in our surroundings.

You currently pay 700 EUR cold rent and save 800 EUR for the house. The ancillary costs for the house tend to be higher because it is larger than an apartment and a detached house generally has higher costs than an apartment in a multi-family building.

That means you are now saving 800 EUR/month, but want to pay 1,300 EUR more "cold rent" for the house, plus higher ancillary costs. How is that supposed to work? According to my calculator, you are already 500 EUR in the negative every month just on the cold rent.

Do not underestimate the outdoor facilities and interior furnishings. You can easily sink another 20,000 EUR into that, just for materials and tools. That only works within a reasonable time if at least 1,000 EUR per month remain for materials.

Ah sorry, overlooked. The balance is 970 EUR, so 1,770 EUR remain per month. With a payment of 2,000 EUR and additional costs of 500 EUR for the house, you have to expect about 1,300 EUR more in cold rent and 250 EUR more in additional costs. That leaves 220 EUR for saving, so to invest in materials and furniture...

How is that supposed to work? Especially since your child is still very small and costs almost nothing. The costs will also increase. Especially if it is going to be another child.

Actually, like many others, it lacks equity. Save or generate another 100,000 euros and then it could work. Include the 100k in the financing, 50k equity in the background.

Everything else makes no sense.

Buy the land now and finance it. That shouldn't be a problem.
