How HDB Contra Facility Helps Your Selling and Buying Timeline


If you are planning to sell and buy your HDB flat, you might have come across this term – HDB Contra or Enhanced Contra Facility.

This word sounds complex, and might be already confusing you, which is why we are going to explain it here and make it simple for you to understand about HDB Contra.

So what is HDB Contra Facility, and how can you make use of it to smoothly sell and buy your HDB?

HDB Contra is a facility that allows you to sell and buy your HDB flat at the same time, while using the sales proceeds and refunded CPF monies from your sale to offset your purchase. This allows the selling and buying to completed on the same day, and will hugely benefit your resale timeline planning as it saves you at least 1 month of transaction processing time.

Let’s dive deeper into understanding the details, so you can know what to look out for when planning to sell and buy with HDB Contra Facility.

Why use HDB Contra?

Here’s a simple example for you to understand why you will want to use HDB Contra Facility if you are selling and buying.

Say you want to sell your flat and buy another flat..

And based on your financial calculation, you will need the cash proceeds / CPF refunded monies from your existing flat sale in order to complete your flat purchase.

If you were to proceed with your selling and buying without doing a Contra, your buying transaction will only be able to be completed about 1 month after your selling transaction is completed.

And this is how your selling and buying timeline will look like:

Not Doing Contra
01 April
Selling Completion Date
01 May
Buying Completion Date

Looking at this example, you will realize that 1 month will be lost to the transaction processing timeline.

And if you managed to get 3 months extension of stay for your selling, you will only be left with 2 months to do your new house renovation and move over.

This 1 month gap will definitely be there if you are not using HDB Contra Facility, because your conveyancing lawyer requires 2 weeks for your CPF to be refunded from your sale, and another 2 weeks to process the usage of your refunded CPF funds for the purchase.

So if you do not have an alternative place to stay while going through your selling and buying process, every day counts and you would definitely want to save this 1 month gap and use it for your new house renovation.

This is where Contra comes in handy, provided you are eligible for it.

If your selling and buying transaction allows for Contra, you should make use of this facility, and your resale timeline will look much better like this:

Doing Contra
01 April
Selling Completion Date
01 April
Buying Completion Date

By using HDB Contra Facility, you can successfully eliminate the 1 month gap, and you will be able to complete your selling and buying transaction on the same day..

Thus allowing you to start your new house renovation immediately, or allowing you to move into your new house immediately.
