What will you do? Sell and buy a new launch pte condo or hold

Like to get some views on the below:

• i’ve a 1br condo that due to some unique circumstances, received a 20% “discount” (thru offsetting of the outstanding bank loan)
• rental vs all-in cost (mortgage, maintenance, prop tax, agent fees) is almost flat so kinda auto-pilot now
• however resale prices been declining, lower than what the original (~5% drop)

• i see very ltd upside

  1) would u sell it and cash in the profit, and use it to reinvest in another 1br new launch
  2) or keep it as-is ?
