Ha well I think then you are asking for wide range if you say by household or by single, etc. Obviously dual income will be $100K+ and single under $100K for the most part. That's why I say it needs to be based on your own income---it's not like you say "Hey I'm married now so now I can afford an X5"---it's most likely based on your own income-- just like if you were single.
