Feasibility financing for new construction

I know the demolition of a single-family house at 200€/sqm.
It should be significantly higher for a terraced house because you have to work much more precisely and carefully...

I can give a current example from our area.
Demolition of a single-family house about 200m2 with a 20t mobile excavator for 4 days at 9 hours each – 3500€.
Disposal of construction debris another 5k.
However, almost only stones, hardly any hazardous waste.
Excavator and pit 1km away.
Everything on site and perfect access.
A mid-terraced house in a residential area looks completely different!

In the southwest: Demolition of 70s asbestos prefabricated house (detached single-family house, living area 128 m²) including basement and garage: 30K cheapest offer, range went up to 37K. It is only one offer, I am curious what will come out in the end.

If you assume 80% loan-to-value, you arrive at the desired €2000 installment with 10 years and currently 1.85% interest and 2% initial repayment. But that is obviously very tight. After 10 years, a remaining debt of €484,000 remains theoretically, but in practice it will be more due to the construction phase.

The 1.85% is probably no longer achievable and they shouldn’t do 10 years either, but rather 25, and then you quickly end up at almost 3%. I just have an offer of 2.2% for 15 years at 50% loan-to-value.

the 1.85% is probably no longer achievable and 10 years should not be taken either, but rather 25, and then you quickly get close to 3%.

I like to use biallo as a guide for interest rates. I have had very good personal experience with it.

With the price difference, one should carefully consider whether to really take 25 years for the extra cost. I would always look at a) what one would like and b) what premium this security costs.

The construction costs are too low for Munich as well. I also don't see any incidental construction costs. Realistic construction prices, higher demolition costs, incidental construction costs in general are missing by 100-150k

if you manage to align the demolition/construction costs and incidental building costs like this, then it could work.

income/financing amount also fits.

you can probably pay for the land from your own capital, only a little is missing for the incidental purchase costs and demolition.

I don't quite understand the calculation with the living area (so there will be 3 full floors?),
because if there will be sloping ceilings in the attic, then you will never manage with 80% of the floor area.
ground floor with your floor area: 75 sqm (of which over 20 sqm garage)
first floor: 75 sqm
attic: 75 sqm minus slopes, minus 2 terraces (22 sqm)
I would say the pure living area is more like 160-170 sqm (ok, the terraces will be partially added)

maybe a brief note on the floor plans (I skimmed through them)
entrance area with 10 sqm (waste of space, especially if you have a hallway with built-in wardrobe on every floor...)
terrace 1 (facing the street!) I would leave out, instead enlarge the living space there, and make terrace 2 at least 1 m wider!
(ok, I don’t know the orientation yet, where south, west is... but just an idea)
because noise level is probably higher toward the street, less so in the yard. Also if the terrace is wider, you can put plants there as visual/noise protection.
why a built-in wardrobe in the bedroom if you make a dressing room? (especially if you then make a 16 sqm bedroom... do you work there (like the children do their homework in the kids’ room because there is no study?)
and if you put the living/dining room in the attic and entertain guests, do they always have to go one floor down and use your master bathroom? or do they go all the way down (2 floors) to use the guest WC?

personally, I find the living/dining area in the attic quite interesting, but it gains quality if there is also a guest WC and a larger terrace.

and since the building envelope (6.7x14.1 m) is given, I would try to create as much living space as possible (i.e. little hallways, entrance area, stairs)

even if it doesn’t belong here ;)
