House building: fits or bursts?

Hello, we, M29 and W32, want to build a house and would like to have a few more eyes look at our project.

It is about a plot of land and a city villa with 140 sqm. Garage, underfloor heating, central ventilation, electric shutters. Otherwise relatively standard.

We are both permanently employed, not married and still without children. Children and wedding are planned though. 2 years parental leave for her if possible. Afterwards, she will work part-time 40-60%.

Income
He: €2,600 without 13th/14th salary and without possible overtime.
She: €1,850 without 13th salary.
Equity planned €60,000 max. €80,000 cash.

The bank (Sparkasse) gave us a calculation example for orientation.
We have no major fixed expenses, only the standard ones like phone, internet, insurance.

Income together: €4,450
- Living expenses: €1,500
- Costs 1 car: €200

Surplus: €2,750

The bank then calculated additional costs as 140 x €2.5 = €350 additional costs so that in the end a possible cold burden of €1,200 was calculated.

I'll leave it at that and would like to hear your opinion on it.

There is also an "offer" from a developer

Plot 850 sqm: €65,000 including 7% property transfer tax and notary.
Construction costs 140 sqm x €1,400: €196,000
Extras construction (ventilation etc.): €30,000
Double garage: €27,000
Additional construction costs: €60,000

Total approx.: €378,000

Missing would still be painting and flooring work.

Is the whole thing realistic?

Is it really a property developer? Then the real estate transfer tax applies to the total price, not just the price of the land. With €1400 per square meter of living space, additional charges are to be expected, so plan a buffer for that. The €30,000 go quickly if bathroom and ventilation (€10-12,000 just for this (central)) are already included. What about the garden? €10-15,000 for minimal ground work/leveling, paving, entrance platform, etc.

Well, even if it is a general contractor, then they also offer the plot of land?! Even then, real estate transfer costs will probably apply to both. You should plan for that. Additional construction costs of 60,000 are calculated very high, how come? You could possibly invest the savings in some upgrade options. I would skip the double garage and pay for the paving with a double carport from the 27,000. Then it should more or less fit. But I am no financial expert ;)

Brief regards

We have no major fixed expenses, only the standard like phone, internet, insurances.

Naked, starving cyclists; freezing and with water from the village well? - hmm, isn’t something missing there?

Otherwise, everything here reads pleasantly down-to-earth, 140 sqm living space on an 850 sqm plot already sounds like reasonable conditions.

However, the plot sounds quite cheap – is it very rural with the downside of a lot of commuting for work?

I meant of course GU. The plot is not included, we would buy that ourselves. Via the NLG, commission-free, fully developed, including street. €57,000 I had now planned a €3,000 buffer for earthworks as well as €5,000 for taxes and notary. Yes, rural, I practically work right outside the door or start with the company car from home, my girlfriend has about a 10-15 km commute. No, no naked cyclists, but costs for car, electricity, gas, groceries are included in the flat rates -living expenses -car (no loan) -additional costs I have estimated incidental building costs -paving €10,000 -garden €1,500 EL -rainwater shaft €2,000 EL -hedge €500 EL -kitchen €12,000 -furniture (partial) €6,000 -lamps €2,000 -electric shutters €5,000 (additional) -ventilation €11,000 -extras/buffer €10,000

I have estimated ancillary construction costs
-Paving €10,000
-Garden €1,500 EL
-Rainwater shaft €2,000 EL
-Hedge €500 EL
-Kitchen €12,000
-Furniture (part) €6,000
-Lamps €2,000
-Electric roller shutters €5,000 (additional)
-Ventilation €11,000
-Extras/Buffer €10,000

Oops... Watch out!!!!
Ancillary construction costs include permits, earthworks, etc. you can't avoid those
Read here:
And also interesting here:

What you have listed (without rainwater shaft) either belongs to exterior facilities or private matters; roller shutters are special equipment.

Differentiate for the calculation:
House costs
Upgrading
Ancillary construction costs
Exterior facilities
Own work (material)
