August 2022 HDB BTO in-depth review with video: Choa Chu Kang (Keat Hong Grange)

BTO season is upon us again, and in this August 2022 HDB BTO review, we’ll be covering the quiet town of Choa Chu Kang. 

A population of 169,000 residents call the sleepy, serene estate home. Located at the north-westernmost point of Singapore’s west region, it used to be home to a kampung village and rubber plantations until HDB started developing it in 1985.

Fun fact: Back in the early days, tigers used to roam in the area before disappearing in the 1930s.

The flats at Keat Hong Grange make up 19.8% of the total units offered. There are a total of 987 units spanning four room types: 2-room Flexi, 3-room, 4-room and 5-room flats.

August 2022 Choa Chu Kang HDB BTO: price range

Here are the price ranges excluding grants:

Flat type Price range
2-room Flexi (Type 1) S$102k – S$131k
2-room Flexi (Type 2) S$125k – S$160k
3-room S$194k – S$243k
4-room S$277k – S$363k
5-room S$390k – S$508k

Estimated downpayment, monthly instalment and income 

Based on these price ranges, we can estimate the downpayment, monthly instalments and household income needed to pay for the August 2022 Choa Chu Kang BTO flat. These estimates are based on the following assumptions:

  • An HDB loan is taken, maximising the 85% loan-to-value (LTV)
  • The loan tenure is 25 years, with the current interest rate of 2.6%
  • There is no other housing loan to service

Let’s put this into better focus by taking the median of the price range without accounting for CPF grants or savings. A mortgage calculator will also be used to work out the math.

Do note that for public housing, only up to 30% of your monthly household income can be used to service your home loan. 

This is called the Mortgage Servicing Ratio (MSR). By taking this into account, we can find the estimated household monthly income needed for the flat.

Flat type Median price Loan amount (85%) Min. downpayment (15%) Estimated monthly instalment Estimated monthly household income
2-room Flexi (Type 1) S$116,500 S$99,025 S$17,475 S$449.25 S$1,497.50
2-room Flexi (Type 2) S$142,500 S$121,125 S$21,375 S$549.51 S$1,831.70
3-room S$218,500 S$185,725 S$32,775 S$842.58 S$2,808.60
4-room S$320,000 S$272,000 S$48,000 S$1,233.98 S$4,113.27
5-room S$449,000 S$381,650 S$67,350 S$1,731.43 S$5,771.43

August 2022 Choa Chu Kang HDB BTO: The Pros

Cheaper, larger flats

Run, don’t walk – 5-room flats are available in the Choa Chu Kang launch. The only other launch in the August 2022 BTO exercise with 5-room flats is the Ang Mo Kio BTO

Due to Ang Mo Kio being a mature estate, the prices are higher than that of Choa Chu Kang. 

The price for a 5-room flat at Central Weave @ AMK is between S$720,000 to S$877,000, while a similar flat at Keat Hong Grange is considerably more affordable at S$390,000 to S$508,000

That’s a price difference of S$330,000 to S$369,000 that you can put towards a decent renovation.

Families looking for more living space should keep an eye on this project. Or if you’re a couple who likes to stretch out and have more dedicated rooms for hobbies, this Choa Chu Kang project will be right up your alley. 

Food and retail amenities

*Disclaimer: Walking, public transport ride and driving durations are based on Google Maps estimates. Actual times may vary.

Keat Hong Shopping Centre is a 6-minute stroll away, where you can pick up fresh produce from the wet market or skip the cooking and head straight to the KFC, Pizza Hut or Dominos. There are also a few food courts for those who prefer local fare.

Home renovation DIY enthusiasts will be thrilled to know that there’s a huge HardwareCity store for all their needs.  

Keat Hong Mirage is just an 8-minute walk away. The development was part of the November 2012 BTO exercise and stands out from the rest of the launches due to its wide range of shops. 

You can find a supermarket, laundromat, barber and clinic. For F&B options, there’s a bakery, ice cream shop, a newly renovated food court and last but definitely the most important – McDonald’s. 

For healthcare facilities, there’s a clinic (OneCare Clinic) within 150 metres at Block 810, or you can get to Ng Teng Fong Hospital within a 13-minute drive via Bukit Batok Road.

Within the development, there will also be a childcare centre at Blk 823. 


If you’re a mall rat, the nearest ones would be Lot One at Choa Chu Kang Interchange and Bukit Panjang Plaza or The Hillion at Bukit Panjang Interchange.

Bukit Panjang Plaza is just a stone’s throw away from The Hillion mall.

They’re pretty small malls, so you might want to take the train to Jurong East, where you can explore more entertainment and shopping options at mega-malls like Westgate and JEM. 


Parents with school-going children will be spoilt for choice when it comes to education. There are many schools in the area for all ages*:

  • Little Footprint Preschool (750m)
  • My First Skool (650m)
  • PCF Sparkletots Preschool (1.4km)
  • Chua Chu Kang Primary School (1.3km)
  • South View Primary School (1.3km)
  • Teck Whye Primary School (1.9km)
  • ASPN Delta Senior School (Special Education) (450m)
  • Chua Chu Kang Secondary School (1.4km)
  • Teck Whye Secondary School (1.8km)
  • ITE College West (350m)
  • Jurong Pioneer Junior College (2.1km)

*The distance of schools are an approximation.

August 2022 Choa Chu Kang HDB BTO: The Cons


The BTO project isn’t within walking distance to any nearby MRTs – Choa Chu Kang MRT station is a 16-minute bus ride away. Keat Hong LRT station is a 5 to 10-minute walk away, which connects in two stops to Choa Chu Kang MRT and three stops to Bukit Panjang LRT. 

We’re patiently waiting for the opening of the Jurong Region Line (JRL), which is projected to open in three phases between 2027 to 2029. 

jurong region line (JRL)

With the opening of the JRL, the nearest MRT stations within walking distance to serve the residents of Keat Hong Grange BTO would most likely be the Choa Chu Kang West MRT and Tengah MRT stations*. Travelling from either station will take them to Jurong East MRT in five to six stops.  

*The names of the MRT stations are working names.

Those who drive can access the Kranji Expressway (KJE) in six minutes via Brickland Road, which connects to both the Pan Island Expressway (PIE) and Bukit Timah Expressway (BKE) in 10-minutes flat. 

Lack of green spaces

There’s a scattering of neighbourhood parks around the area, but nothing to write home about. Nature lovers can get their fresh air fix at either Keat Hong Garden (a 3-minute walk) or Tembusu Park (a 9-minute walk).

Alternatively, the next decently-sized park would be Choa Chu Kang Park, a 5-minute drive or 20-minute walk away.

August 2022 Choa Chu Kang HDB BTO: Where are the best stacks with the best views? 

Keat Hong Grange BTO is mostly surrounded by current and future residential developments. So if you’re looking for an unblocked view, your best bet would be to get a unit at one of the stacks facing schools. 

These include north-facing stacks 480, 482, 484, 458 and 460 that face a site designated for a school.

You might also want to consider the south-facing stacks 444, 442 and 440. If your unit is high enough, you might just be able to get a view of Bukit Gombak Hill, including Little Guilin. 

August 2022 Choa Chu Kang HDB BTO: Price appreciation

Over the last decade, Choa Chu Kang has seen a price appreciation of 17.15%, with 5-room flats seeing a slight advantage (16.87%) in appreciation over 4-room flats (16.17%).

Recently MOP projects in Choa Chu Kang

We look at past BTO projects with freshly completed MOP in 2020 and 2021. In these examples, we’ll focus on 4-room flats as they’re the most commonly sought-after flat type. 

For reference, the Q1 2022 median HDB resale flat prices for 4-room units in Choa Chu Kang is S$470,000.

Here are the numbers when these BTOs first launched.

Keat Hong Quad (Sept 2012 BTO), MOP 2020/2021

  • Median price: 4-room S$268,000
  • Current price: 4-room S$548,857
  • Appreciation: 104.7%

Keat Hong Colors (Jan 2013 BTO), MOP 2021

  • Median price: 4-room S$260,000
  • Current price: 4-room S$529,741
  • Appreciation: 103.7%

Keat Hong Pride (May 2012 BTO), MOP 2020/2021

  • Median price: 4-room S$254,000
  • Current price: 4-room S$514,288
  • Appreciation: 102.4%

Keat Hong Mirage (Nov 2012 BTO), MOP 2021

  • Median price: 4-room S$276,000
  • Current price: 4-room S$530,000
  • Appreciation: 92%

Why the high price appreciation? 

For one, flats in relatively ulu areas like Choa Chu Kang tend to be cheaper, attracting more buyers looking for more bang for their buck. 

It might also surprise some people to find out that Choa Chu Kang made the list of top 5 HDB towns with the highest average price psf appreciation


August 2022 Choa Chu Kang HDB BTO: Conclusion

Having been a resident of Choa Chu Kang for my entire life, here’s my take on buying a unit here. 

If you love the hustle and bustle of city life and being a few stations away from town, Choa Chu Kang may not be suited for you. 

However, if you love large apartments at a friendly price point and living in a peaceful environment, you should definitely keep this project at the top of your list.
