It's a toss-up in the current market conditions. It's been a buyer's market for resale flats for the past couple years (i.e., buyers are spoilt for choice, so if your unit doesn't stand out, it might be difficult to sell it). That said, if you're willing to put in the necessary work before selling it, now might be the only time you have in the next few years. Most of the major financial indicators are that Singapore is headed for a technical recession, which would negatively impact property prices. Zhi Cheng raises a good point though: if you're coming back from your overseas work in a few years, it might be worth it to keep the property so you have a place to stay.
