More than 30% going to housing is non-sustainable. In fact, it's consider poverty inducing by living wage proponents because it strips so much income that you have no cushion for disruptions.
Basically, 1/3rd of Irvine is living with unsustainable rents or housing expenses.</blockquote>
It depends on your income level and lifestyle.
If you made $100k/year and spent $30k on housing related expenses, you're not in poverty. With higher income, if you opt for more expensive housing, you can "downgrade" to driving a Honda Accord instead of a BMW. The same would not be true for someone making a lot less, however.

<em>Overspending in these big areas is also a problem because we often make commitments for months or even years in advance. It's not like your electric bill. If it was too high last month, you can start turning down the AC today. But, if you agreed to make forty eight auto payments, there's not much you can do about it for awhile. Or, if you do make a change, it will significantly disrupt your lifestyle.
Let's suppose that Michael's take home pay was $2,000 per month. He really wanted an apartment that cost $800 (40% of his income). Add his car payment ($225), gasoline ($75), groceries ($150) and restaurant meals ($150). That totals $1,400 and only leaves him $600 to cover debt repayment, clothing, entertainment, medical, miscellaneous, savings and any unexpected bills. Chances are that he'll quickly be putting some of those expenses on his credit card and adding to the unpaid balance. At some future point that will come back to haunt him.

If Michael were making a lot more he'd have more flexibility. If his monthly income were $10,000, it wouldn't make as much difference if he spent 35 or even 40% of his income on housing. He'd have more in other categories to make up the difference.</strong>
Most of us live with limited income. It's important for us to get our housing, auto and food expenses under 60% of our take home pay if we're going to keep from getting into financial trouble.</em>
