Is financing a new building feasible?

Hello dear members

The following situation regarding our financing for a new building:

He: 3000 euros
She: 1400 euros

From April, there will be a baby, so 190 EUR child benefit will be added, but only about 430 EUR parental allowance for 2 years.

So that makes a total of 3620 EUR net.

Expenses are assumed as follows:
- House costs including electricity, heating, insurance: 600 EUR
- Car (only one, he has a company car): 100 EUR
- Household: 700 EUR
- Child: 450 EUR
- Other insurances: 200 EUR
- Miscellaneous: 200 EUR

Totaling 2250 EUR.

Our bank advisor made us an offer with a building savings contract, acceptance of 1300 EUR + 40 EUR VWL (already included in his net income). She wants to work part-time again after 2 years.

Is this financing realistic? The construction project costs about 390,000 EUR including all additional costs, 40,000 EUR equity is available.

A car costs on average 509€/month. This includes a new purchase as well as taxes, insurance, maintenance costs, or tires/tire changes. You have calculated the house costs very high for that. 2-3€/sqm is usual. Read the pinned post from tox... and calculate again Regards

A car costs on average 509€/month.

Well, expecting that probably makes very little sense. The costs depend too much on the vehicle and usage. Our two cars cost all-in less than 200€ each per month.

And what about renewal?
Whoever owns a car and relies on it has to set aside something in the low three-digit range monthly or rob grandma. It doesn’t matter whether you drive an old Golf or finance a new vehicle. Costs always somehow arise.
I didn’t make up the 509 (-9)

And what about renewal?

Depreciation is included. All-in, basically.

Sure. But in an average, all vehicles from German premium manufacturers with 30,000 km p.a. mileage are also included. That is extremely distorted if you don't participate in this system. Therefore, I think it makes no sense to generally work with this "shock" value.

We should not stray from the topic here

Insurance costs 50 EUR per month, 50 EUR more for fuel. These are the fixed costs. Purchases like tires or inspections are categorized under Miscellaneous with 200 EUR per month.

And I’m not interested in depreciation for now, I’m concerned with ongoing costs.

The house costs have been confirmed by the developer, the house including the garage costs 238,000, 55,000 for the land, the rest are construction and ancillary costs...

Back to the topic: Is this a reasonable financing?
