Moving House?

Today is the 2nd time we are viewing a 3 room flat at Empress Road... not sure if it is a wise decision to move there. There're a few plus points of moving, 1st we'll be cash rich (to be able to make our new place child friendly, and earn interest with the remaining cash), 2nd there is Nanyang Primary nearby, 3rd we'll be nearer to my mom's place. The huge downside would be the space limitation, and lost of privacy cos its a corridor unit.

We can stay put at our current unit and enroll Ethan into St Andrew's Primary School and then ballot for the new Strathmore units? But the timing doesn't seem right.
