Single-family house from 1987. Evaluation of the price and the "necessary" work

According to the KfW FAQs, material costs are subsidized for renovation work done in-house.

Quote from the KfW information sheet on eligible measures:

In this respect, you can carry out the work yourself, but you will not receive funding for it. This was changed some time ago. I still have an application from 2020, with which I can do EVERYTHING myself and still get material funding.

sporty?

I think sporty, because it’s not just these measures. KfW is relatively easy; with 55 it really gets tough. You will probably also need a controlled residential ventilation system and thick or high-quality insulation (= expensive).
By the way, KfW also funds the removal of floor coverings and screed as well as doing everything new, if you install underfloor heating. Etc.

A new roof with insulation can easily cost €40k or more. Heating with everything = €20k. Windows depending on size also €15-20k (don’t forget the front door – I hope the basement has internal access with a door. Open basement access to an unheated basement practically excludes KfW 55). Basement ceiling €1-2k. External insulation €20k. Decentralized controlled residential ventilation €5k.
Then you’re already at €107k. It can also be more expensive.

Ok, then we tick off 55 and focus on 70 :D

The basement has no door.

At €107,000 I would be fully on board :)
Good to know that my estimates are fitting
- Roof €35k (I can provide scaffolding + cover. I have contacts for that)
- Heating €20k
- Windows + front door €20k
- Exterior insulation €20k
- Insulating basement ceiling €2k
= €97k

Controlled residential ventilation would probably be dropped for 55 anyway, right?

I hope and think that this should roughly work out.

The question would then be: is the effort for the underfloor heating worth it? But I think the energy consultant will have something to say about that.
And if underfloor heating, that would probably add another good €15k I think

Here is an update (even though basically nothing has happened)

- The house is still listed as reserved on the real estate portal
- After last week another viewing appointment with the owners was supposed to take place, it was canceled by the owners (they just got back from their vacation)
- today I called the agent to ask what’s going on and what the status is:
The owners are currently buying a new property, but somehow there are issues. Furthermore, the owners have been on vacation again since Monday for 2 weeks. That means nothing will happen for now...

Everything is somehow very strange. Now it means waiting another 2 weeks... the waiting is killing me :D

Everything is somehow very strange. Now it’s said to wait another 2 weeks... the waiting is killing me :D

Then you shouldn’t build :-) We waited 9.5 months for the building permit :-) Fingers crossed.

I can top that with 1.5 years in Cologne :)
