Can First-Line Supervisors of Mechanics, Installers, and Repairers afford to live in Baltimore County, MD?
The 30% rent guideline
A common rule of thumb says rent should stay under 30% of gross income. For a gross salary of $82,690 that ceiling is $2,067 a month. The one-bedroom Fair Market Rent of $1,625 is $442 under it, so rent fits the guideline. Put as a wage, covering a one-bedroom at the 30% guideline takes $31.25 an hour; the median for First-Line Supervisors of Mechanics, Installers, and Repairers is $39.75, which is 27% above that mark. Another way to see it: at $30.35 of take-home pay an hour, a one-bedroom takes about 12.4 working hours every week.
Splitting a two-bedroom
Sharing a two-bedroom at $2,006 a month means $1,003 each. Compared with renting a one-bedroom alone, that saves $7,464 a year. With a roommate, the yearly margin after the basics becomes $43,597.
How fast you can save
At $3,011 a month of margin, building a $10,000 emergency fund would take about 4 months. Setting aside half of the margin stretches the same goal to about 8 months. These figures ignore interest, raises and any spending beyond the four basics.
