Both the verb 'to live' and 'to dwell' can be used in the context of living/dwelling in a house.
However, 'to dwell' is older English and would not be used often these days in that context.
Both verbs have broader meanings and that is where they differentiate.
'To live' is both where you live (i.e. I live in Rome, I live at home, I live with my parents) as well as the act of being alive (i.e. I want to live a good life).
'To dwell' is similar to the verb 'to linger'. It means to stay on something in a (usually negative) context and is often only used in a modern context in relation to thoughts. For example, 'don't dwell on bad thoughts'. Most often you will hear it used in the phrase 'don't dwell on it', which essentially means don't think about it.
