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

The energy consultant says for example. Roof new 45,000€ Heat pump 25,000€ Windows + front door 25,000€ Total 95,000€ So I could get 95,000€ from KFW. But then the above-mentioned work MUST be carried out entirely by the individual trades (material + labor) If, however, I say, material for: e.g. Roof 30,000€ Heat pump 20,000€ Windows + front door 20,000€ So total 70,000€ And I install it myself I do not get any funding. I would then have to take out these 70,000€ at current conditions "normally" without KFW. Is that understood correctly?

Yep. That's exactly how it is.

Or am I missing something?

No. The calculation only becomes interesting if you do not buy the services at a discount but do everything completely on your own.

Although I assume the 0.65% for KFW are unbeatable.

KfW is getting more expensive too. With the classic 30-year term, you are already at 1.14%

all right. Thank you very much :)

The KfW is also becoming more expensive. With the classic term of 30 years, you are already at 1.14 %

How does it look with the program funds in the budget? There was something already, and since then things haven’t gotten any better for the federal government..

Hello everyone,

next Wednesday we have the next/last appointment at the house with the owners.

I would like to have your opinions on the undertaking once again.

Briefly the key facts

House itself, plot, location perfect for us

Built in 1987, Fischer prefabricated house (belonged rather to premium manufacturers?!)
Gas heating from 2011
Windows from 1987
Conservatory – if you can even call it that. Approx. 1.15m x 3.20m (see also attached)

Attached is also the part from the energy certificate again

The main issue here is the enormous consumption. Apart from the renovation, if we:
- replace all windows (triple glazed + warm edge)
- new front door
- either remove the conservatory and have “just” a glass front (sliding door or normal door) or a new conservatory
- insulate the basement ceiling
do, the consumption should go down significantly? I also think this current conservatory definitely consumes a lot of energy?

We are generally rather economical and even now have by far the lowest consumption in our condominium. So the additional costs should stay within limits, right?!

Additionally, the option of a new roof with a photovoltaic system is on the table.

1. How would you rate this idea(s)? Especially the renovation with or without roof?!
2. I would probably not replace the heating at first. Mistake?!
3. Would solar thermal possibly bring something? The general tenor is rather photovoltaic or nothing

My only concern is the question: Can we bring the house up to date with the above-mentioned work? (of course not a KfW 40 new build). Currently we also live with gas heating. and it is from around 2006.

I somehow need some encouragement or some counterarguments

Thanks to you

1. How would you rate this idea(s)? Especially the renovation with or without the roof?!

Basically, you are on a very good path with this. But I would definitely address the roof. Maybe it can also be done simply from the inside.

2. I probably wouldn't change the heating at first. Mistake?!

Not change it yet.

3. Would solar thermal possibly bring something? The general tenor is rather photovoltaic or nothing at all

It brings something. But it's not profitable.

Can we make the house up-to-date with the above-mentioned works?

A clear yes - with the roof.

quick update:

The house has been reactivated on all portals (I think since Saturday evening). I'm not sure how to assess that :)

In the best case, previous interested parties have now all dropped out, so the realtor still sees his chances slipping away :) I'm very curious about Wednesday.

May I share real estate links here? Otherwise, here is the listing ID for E**y Classifieds, in case anyone wants to take a look -> 2168808113
