Purchase decision small semi-detached house 100 sqm from 1930

I did a rough calculation, what do you think? Are the values plausible? I assumed funding from BAFA (heating replacement 35%) and KfW (individual measures, 15% of €60k). Too optimistic? Or even set too high for the small area of 110 sqm?

Disposal gutting €2.5k Roof with overlay insulation and 1x skylight €45k Heating and sanitation €35k Kitchen €15k Guest WC and bathroom sealing, tiling, sanitary fixtures €10k Vinyl/parquet floors (material only) €8k Windows 5x small (basement, guest WC), 1x lift-and-slide terrace door, 8x standard size, front door, single garage door, basement door €22.5k Basement ceiling insulation (material only) €2k Drywall walls (approx. 10 linear meters material only) €5k Interior plaster (basement material only, rest outsourced) €12.5k Electrical (material only + acceptance by master craftsman company) €12.5k Interior doors (material only) €3.5k Furniture €7.5k Other items (structural engineer, energy consultant before work start, unforeseeable...) €20k Photovoltaic system €20k = €221k

- Funding 35% of €40k = €14k - Funding individual measures roof and windows 15% of €60k = €9k

= €197k

I always thought that the funding for BAFA and KfW comes from one pot and that therefore the €60,000 for both together is the limit per residential unit. Am I wrong?

An old Daimler that consumes 20l of premium gasoline per 100 km will still work for many years….that’s why the question(s) about the current (future) total costs…
(Although in your case the consumption isn’t particularly high, but the kWh is/is going to be expensive…)

That would surprise me, I do not know exactly yet. Maybe someone here can help.

You will receive the funding based on the final number of residential units achieved. So 2 x €60,000 per year. The heating subsidy also comes from the BEG-EM fund (EM=individual measures). Together from heating + other individual measures, you can therefore get costs of €120,000 funded by BAFA.

So our energy consultant wrote the following to me regarding the same question:



For us, there will be 2 residential units, hence the 2x. If BAFA and KfW were separate funds, we could have set 240,000€.
