Would it be better to sell my BTO due to 'old age' of the flat or rent it out?

What would you do with the money if you sell?

The key question is always the same: how to best optimize your money?

Firstly, is working overseas permanent?

When it comes to HDB, I try not to look at “current market conditions” but rather do the simple math, if you rent out your flat, it could fetch $1200 a month, you have to pay to cover some tax and commission so maybe you end up with about $10k a year extra.

If you sell the flat for $400k and put all the proceeds into CPF OA, you can get 2.5% annually compounded that is risk-free $10k.

Or if you invest it to get 5%, you get $20k annually.

The numbers surely vary so do your own homework before taking action.

I would recommend you to rent it out.

If you rent it out, you will get cashflow.

For example, based on a 4 room hdb flat, monthly rental is $2000 * 12 = $24000 per year. Furthermore, your house got only left 80 years.

So yearly rental which is $24000 * 80 years = $1920000.

So if you rent out for 80 years, the total rental earned would be potentially more than your capital gain.

Capital Gain = Sell Price - Buy Price of your property.

However, if you use this capital gain to reinvest, then I recommend you to sell your BTO due to 'old age'.

After you sell your property, you will receive capital gain.

You can use your money earned from capital gain, to reinvest in other financial instruments.
