Construction financing single-family house - What is possible, what do you advise?

You should be able to repay the BAföG in one lump sum and even get a large discount!

Otherwise, I find the house size with a basement a bit much. But well, you never know how many children there will really be!

You definitely can. I just looked for a note on my notice and didn’t find one. I need to get in touch directly with the contact person there. Thanks!
Well, the plan is for three at some point. But of course, you never know how quickly such plans can change.

Thanks for the assessment!

We like to calculate here with 2000€/m² plus ancillary construction costs, basement, outdoor facilities, garage.

The hillside location can really get expensive cost-wise, and building without a basement might no longer make sense. You also have (expensive) special requests like the potential granny flat and the insulated double garage. Without knowing the details, I fear this is going to be a bit too much, especially considering parental leave.

Are there already planning details?
Can you tell us more about the plot, or upload a site plan? Or are there already plans on how you envision your house?

I currently do not have a site plan available.
I will try to describe the plot in a bit more detail:
-The plot is accessible from the street level at the front. After about 2m into the plot, there is a slope of approx. 20° downward.
-The ground floor could thus be entered on ground level, as could the garage.
-After our plot area, a hillside begins, which has an incline of about 30°.

If one makes a rough cost calculation for the construction (clearly most figures are estimates), I suppose the following listing arises:
-->See attachment: (approx. €465,000)

1	Site development	Excavator, earthworks	€25,000.00
2	Earthworks on the plot -Compaction, etc.	Excavator, disposal via truck costs	€10,000.00
3	Foundation	Much own work	€25,000.00
4	Masonry Ceiling elements	Can help themselves as well	€150,000.00
5	Sanitary	Company	€35,000.00
6	Electricity	Self	€15,000.00
7	Living space apportionment	€35 /m² at 165m²	€10,000.00
8	Roof works	50 / 50	€60,000.00
9	Floor works	Self, (tiles company)	€20,000.00
10	Plastering	Own work due to company	€10,000.00
11	Interior furnishings	Kitchen etc.	€80,000.00
12	Outdoor facilities	Own work	€25,000.00
Total:	€465,000.00

What do you think of this list?
As I said, it is intended to serve as a first impression.

Thanks in advance

One more question: What is your monthly net income? So without sales bonuses, Christmas bonus, etc.

Monthly net income:
He: €2300 (Pure base salary, without commissions, Christmas bonus, etc.)
She: €1600 (Pure base salary without Christmas bonus)

Current monthly expenses:
-Both values are currently maximum values here: €1400
(Insurance, savings contracts, vacations, groceries, rent, etc.)

We have assumed minimum values here. The rest should serve as possible leeway. Vacation, necessary short-term repairs, special repayments... Are somewhat conservative here.

Thanks in advance

The 165m² living space should include the habitable roof of the garage.
I'm thinking of a children's room/guest room or something else.
Due to the property, I think the basement is more pleasant and overall probably cheaper.

Details about the property:
- Slope location where the street accesses the highest point of the property
- From the street, it goes about 15m back and about 3-4m down
- Behind our property is a relatively steep slope

--> Therefore the assumption that a basement is cheaper + easier for us to implement

Yes, I don't dispute that and also think that a basement is more economical. We have a similar situation and will also build with a basement. However, the office and guest room will then move to the basement and the house "above" will only be 140 sqm. You want 165 sqm upstairs, right? Do you actually need that much?

With all due respect, I think the room above the garage is nonsense. From which American movie did you get that idea? Would you want to live there?

How do you mean? Have you already received a notice with a payment request or are you still waiting for it? If you already have it, it states how much you have to pay if you pay it all at once. How much do you save there? I would pay back BAföG before you enter financing discussions, because questions about such things will of course come up and if you can then say "BAföG loan has already been repaid," that obviously sounds better than if it is still outstanding.

I am also currently in financing discussions, but nobody really cares about the BAföG debts that are due at the end of 2020. The conditions have not worsened by even a tenth of a percent. One advisor said that BAföG debts are the best debts you can have.

Yes, I don't deny that and also think that a basement is more economical. We have a similar situation and will also build with a basement. However, the office and guest room will then move to the basement, and the house "above" will only be 140sqm. You want to have 165sqm upstairs, correct? Do you really need that? With all due respect, I think the room above the garage is nonsense. From which American movie did you get that idea? Would you want to live there?

We arrived at 165sqm because some time ago we looked at a show home that was about this size. The 165sqm is not strictly necessary. I am interested in opinions and reports of experience here. Especially regarding possible family planning, etc. Since you have similar conditions. Do you already have a cost calculation that you might provide to me? I believe that would be a great help for us. The garage is to / can connect directly to the house. Of course, there is also the possibility to omit it entirely, but we quite like this building form, which is why we came up with the idea. What reasons do you think speak against a room above the garage? Thanks for the honest opinion!
