When you're an expatriate for a short while, it's wasteful to splurge on furniture and art. Your ticket home is like your ticket to heaven. You can't bring your stuff with you.
That doesn't mean you can't personalize your place for cheap. My apartment is looking cute, for about 60,000 W (60 USD). Here's how:
Striped rug- 2$, dollar store at South Gate
Computer desk- approx. 30$, HOME PLUS
Candle- 1.30$, HOME PLUS. The holder was a gift.
Frames- 4$ for two, HOME PLUS
Framed poster: 20$, HOME PLUS
Coat hanger hook: $1, at any stationary store
Grand Total: 61$ USD
