Bro, it depends on individual. How much are you willing to part with $ in exchange for the luxury as well as comfort.
For FH condo at 560k looks a very good buy. Btw, where is it? Size? 2 room should be around 1000 sq ft. I got a friend who own a FH 980sq ft at the east recently sold for $620k. Bought at 2000 for $440k. The property was more then 20 years old. The scenary is very nice though.....18th storey.
At $560k, assuming u pay up 20% (10 via CPF, 10 via cash)
So you will loan approximately $450k. Base on current interest board rate, your monthly installment should be around 2k+ per mth. This is of cos base on 30 years loan tenure. Assuming total income is $8k (each is 4k) per couple, each will have contribut about $1k to your CPF ordinary account. That excludes the 2.5% interest you will earn in your CPF account as well as the variable bonuses your employer will present to you.
As such, you should be a reasonably healthy level if you were to purchase this property. Both of the CPF account will not exhibit any deficit.....
Good luck bro.
