Energetic renovation, financing and KFW 261

With a 40-year-old oil heating system, I think I would take immediate action if at all possible.

Definitely, currently it depends more on equity this year; we expect better cash flows in 2025/2026, so we could pay for it from equity without taking on additional loans.

In option A, I see the individual items as rather more expensive. Painter for €6k for almost 200 sqm is hard for me to imagine.

Basically correct, it costs me €25/h for the apprentice + €45/h master - assistance is done by own work. We have already done this this way during the renovation of my current rental property.

The floor will probably also be more expensive if the floor heating is supposed to be included in the €17k.

The calculation is based on the information from my screed layer, who does it this way for €12/sqm for laying screed + approx. €10/sqm material.
Additionally, insulation, stapler boards, installation and the floor covering (vinyl planned, self-installed).

The hints have been very valuable so far.

I have seen that the KFW loan 258 for supplementary measures might actually be possible because the incomes from 2021+2022 are considered; here we still meet the limits of €90k. This could possibly create further scope through lower interest rates.

We have now made some progress, the purchase price of €510,000 has been confirmed, and we have come to the conclusion to possibly carry out further energy-related renovations. An energy consultant will now inspect the building to create an iSFP, and a friend who is an architect will also be involved in the planning.

The use of the building is initially divided as follows: owner-occupied on the ground floor, rental on the upper floor for at least 4 years. (Income approximately €550 cold rent per month)

Funding is planned to be used as follows:
- KFW 358
- BAFA individual measures
- BAFA heating technology, would be 55% (30% basic, 20% speed, 5%)

Renovation components:
- WLP
- Underfloor heating ground floor + upper floor
- Facade insulation
- Replacement of windows up to 90%
- Replacement of front door
- Basement ceiling insulation
- Roof, depending on cost -> installation of dormers, new roofing, insulation between rafters
- Interior: wall renovations, mainly painting; room doors; floors

The following will not be fundamentally renewed:
- Electrical system
- Water system
- Staircase

Now we are very curious to see where we will stand price-wise with "real" offers and to what extent a KFW efficiency house standard will be achievable.

I am curious as well. Whether it will be KfW XY is up to you. Since you can and want to insulate everything around + heat pump with underfloor heating + new windows (please also install a ventilation system, preferably decentralized), you can also achieve KfW 40. I see 55 as easily achievable (from experience). You just have to tell the planner what the planning result should be.

I am curious too.

Hello,
we have now had the conversation with the energy consultant, attached is the update:

a) KFW85 would be possible in the area with 1) WLP 2) 18cm intermediate rafter insulation WLG35 + 4cm under-rafter insulation 3) 12cm cellar ceiling insulation 5) photovoltaic 6) window replacement at least 0.8 Uw 7) facade insulation at least 10cm
Electricity costs approx. EUR 1314

b) Without KFW "standard" it would be analogous to KFW85 without photovoltaic and without under-rafter insulation and slightly lower Uw values allowed for BEG EM funding.
Electricity costs approx. EUR 1534
-> This is the calculated solution.

c) KFW 55, we have not calculated, as facade insulation and roof insulation are currently not an issue but would be necessary.

The bank has also submitted an offer under the following assumptions (small adjustment loan amount EUR 600k due to small loan limit):



Loan details:
- Also includes 4x repayment changes
- 5% special repayment


We are currently checking whether the energy renovations can be done via KFW 358/359.

We can discuss the 1% repayment, this can be adjusted by special repayments and is planned.
The household income is approx. EUR 9000 / month and there is a multi-family house with a surplus of approx. EUR 450/month.

In my assessment, in the current interest rate environment and with the favorable loan-to-value of 90%, a good offer already.

Best regards
