What is included in Kommunale Avg?

Done living in large apartment buildings. We are looking at Selveier house after living in a Borettslag and I'm trying to understand how different it will be.

What is usually included in the Kommunale Avg and what expenses would you need to add on top that would typically be included in Felleskost? I imagine that we will get worse deals on things like Internet/TV.

One of our worries is, if we do need to make repairs, how easy is it to get an extra loan or increase the mortgage? How easy is it to get a contractor? I've seen that when contracts are too small, some companies don't even bother.

Anything else we should be aware of? I'm reading the condition reports, but how do I estimate the condition of the exterior? (Roofs, walls...)

Another option would be a semi-detached house as Andel. No more worries about the exterior, but I'm unsure what we should be careful about when looking at houses. Are there some with a private garden? Doesn't seem very common.

Thanks for helping a noob
