回複：現有mortgage,不算太多，想換大房子，不專為投資。

想換房子就換，沒有說什麽是時候，經濟許可就是時候，你隻是換房子，如果房價高，你的房子也會賣得高，你的房子價錢LOW低，你要買的房子相對也會低。

IF FOR ME, FIRSTLY,I WILL GO TO FIND THE NEW HOUSE I LIKE,SECONDLY, I WILL CACULATE THE COSTS OF THE NEW HOUSE, AND CAN I OFFORD IT, EVEN AFTER SALE OF THE PERSENT HOUSE, MAY BE IT NEEDS A BIT MORE ON THE TOP OF PRESENT MORTGAGE WITHOUT EFFECTING THE LIFE SYTLE I HAVE NOW.

GOOD LUCK
