First, the money is stupidly good. In cities like San Francisco, a spare closet can fetch $1,200 a month. That’s a vacation to Cancun every year, just for tolerating someone else using your microwave at 2 AM. Cha-ching.

Third, tax benefits. The IRS lets you deduct a portion of your mortgage interest, property taxes, and utilities if you rent out a room. Just don’t try to claim your imaginary friend as a dependent. The IRS has seen that trick before.
