Several years ago a neighbors house burnt to the ground. Never having deal with a situation like that I called my insurance co (State Farm) and asked what happens in that situation.
The Short story: They pay for a new house. The contents are (IIRC) like 75% the value of the house. That includes EVERYTHING inside the house; furniture, dishes, clothing, TV's/electronics ect...
Basically, they cut you a check for the content value and you spend it however you want.
So your $100,000 house gets you a check for $75,000 that can be used for $70,000 in new A/V gear and $5,000 for furniture if you want to. aa
