Selling Apartment

Not us, but I met my neighbor upstairs at the elevator last night while I was rushing to visit a friend's mom at NUH. He told me he has recently sold his apartment for about 740K and bought a maisonette at Sunset Way for about the same price. He explained why financially it made sense. That gave me pause and perhaps I also better make some calculations. We really have no need to be here any more. My in laws were gone long ago. Very soon none of the kids would need to go to the school near by.
