Well, realistically, without making any changes to income or out-goings, the Simpson family would be unable to continue living at 742 Evergreen Terrace. With an income of $4,299 per month, and out-goings of $5,788.76 per month, the Simpsons should realistically have gone bankrupt a while ago, and would likely be unable to afford ANY home within Springfield.
However, the Simpson home is rented from their extremely kind, understanding, Christian neighbour Ned Flanders. Let’s just imagine that Homer could persuade Ned to let the family live rent-free, the family would still be unable (just about) to make ends meet with their total out-goings still sitting at $4,491.76 per month (just $192 over their monthly budget).
Although, let’s not forget who we’re talking about here. Homer doesn’t exactly tend to think things through, and almost never consults his family about any decisions he’s making, and so we wouldn’t be surprised to see him cut costs in any and all places possible. We imagine that he’d be more than happy to stop paying for healthcare – “That’s a problem for future Homer” (knocking their outgoings down to $3,341.06 per month), and would be even less surprised if he opted to cut transportation costs by selling one of the family’s two cars (further knocking their outgoings down to $2,729.06).
While this entire cost cutting exercise would be a little over the top for the average person, Homer isn’t the average person, which is why cutting these costs seems almost normal for his character. In the end, with these reductions in out-going, the Simpsons family would be able to make ends meet and keep their home at 742 Evergreen Terrace, with $4,299 of income and now only $2,729.06 in out-goings, meaning they’d even be able to afford to pay poor Flanders his rent!
