What equipment is for resale value

Unless it is high-quality parquet, the floor is usually irrelevant. No one cares if the tiles are high-quality if they don't like them. Usually, it is very personal anyway whether a house sells well. Ignoring the location for a moment. Nowadays, anyone who builds without [Fußbodenheizung] hasn't got the message. I also think the energy standard will be important. Good electrical installation so you don't have to deal with it later. I see the basement as a bonus and it won't recoup the costs. Well-maintained outdoor areas are important. Overall condition of maintenance.

Apart from the already mentioned location, building fabric, and technical equipment, ultimately the visual interior design is important:

When we looked for something used on Immoscout and similar platforms, the following things were always viewed negatively:

Five different colors on the wallpapers.

Bathrooms tiled in Bahama beige or summer green, or corresponding sanitary ceramics.

Oppressive wood paneling on walls and ceilings.

Kitchen fronts in purple or similar colors.

Sure, these are houses that are twenty or more years old. But in terms of a modern new build, it might make sense to choose a timeless color scheme.

Then the potential buyer might not say in twenty years:

Repaint the hallway, remove and retile the bathrooms, replace sanitary ceramics, new kitchen — that easily amounts to 30-50k€ which will then lower the purchase price because otherwise the house wouldn't even be considered.

Additionally, certainly energy standard /energy concept/ actual consumption - is already quite important and will increasingly come into focus.

Tastes change. If I build now the way I want to sell later....

in 10 years, "smart home" might be everywhere. And your pad will be antique

that's the end

But he is still right... When I think back to my 'used house search'... Timeless bathrooms are much better in terms of value retention than currently trendy bathrooms.

The currently fashionable typical tiles with ornaments will definitely be considered quite ugly by most people in 10 to 15 years and thus the bathroom will be seen as a complete renovation, similar to how we currently feel about the beautiful brown yellow pink green bathrooms. This is not the case with timeless bathrooms. Whether this criterion is important to someone when building or not was not the question, but only the value retention.

I agree. Especially those looking for "old" used properties usually do not require a current color scheme but already calculate the costs for a new bathroom, new kitchen, tiles need to be replaced anyway, wallpaper new, etc. Even if it might still suit your taste, the new owner may simply want it to be new.

What is often crucial is really the electrical system, (currently still) water, sewage, energy standard, type of heating...
