Can Bus and Truck Mechanics and Diesel Engine Specialists afford to live in Orange County, CA?
The 30% rent guideline
A common rule of thumb says rent should stay under 30% of gross income. For a gross salary of $77,380 that ceiling is $1,934 a month. The one-bedroom Fair Market Rent of $2,610 is $676 over it, so rent breaks the guideline. Put as a wage, covering a one-bedroom at the 30% guideline takes $50.19 an hour; the median for Bus and Truck Mechanics and Diesel Engine Specialists is $37.20, which is 26% below that mark. Another way to see it: at $28.80 of take-home pay an hour, a one-bedroom takes about 20.9 working hours every week.
Splitting a two-bedroom
Sharing a two-bedroom at $3,057 a month means $1,529 each. Compared with renting a one-bedroom alone, that saves $12,978 a year. With a roommate, the yearly margin after the basics becomes $31,960.
How fast you can save
At $1,582 a month of margin, building a $10,000 emergency fund would take about 7 months. Setting aside half of the margin stretches the same goal to about 14 months. These figures ignore interest, raises and any spending beyond the four basics.
