253 Ang Mo Kio Street 21 HDB Investment Analysis: Understanding Growth Potential in Ang Mo Kio
Block 253 Ang Mo Kio Street 21 represents a compelling investment opportunity for HDB resale buyers seeking established estate stability combined with genuine capital appreciation potential. Built in 1996 with a 99-year leasehold tenure, this 12-storey block of 110 units has demonstrated consistent price growth over the past five years, making it an attractive option for both upgraders and investors navigating Singapore's HDB resale market.
This investment analysis examines the real growth potential at 253 Ang Mo Kio Street 21 by analyzing transaction data, market positioning, and the factors that drive value in one of Singapore's most established HDB towns. Whether you're a first-time buyer or seasoned investor, understanding this block's investment fundamentals is essential for making a confident purchasing decision.
Recent Price Performance: What the Data Shows
Transaction data from 253 Ang Mo Kio Street 21 reveals significant appreciation over the past five years. In January 2021, a unit sold for S$670,000 (S$487 per square foot). By August 2025, comparable units were transacting at S$1,010,000 (S$691 per square foot)—representing approximately 50% price growth in just four years.[1][4][6]
The most recent transactions show price stability in the S$938,000 to S$1,038,000 range for 5-room units, with per-square-foot pricing ranging from S$682 to S$721.[3][4][6] This consistency suggests the market has found an equilibrium price for this block, reflecting genuine demand rather than speculative activity.
Breaking down the growth trajectory: units that sold for S$560,000–S$630,000 in 2012–2014 have appreciated to S$938,000–S$1,038,000 today. This represents approximately 50–85% total appreciation over a 10-year period, or roughly 4–6% annualized returns—well above inflation and comparable to many private property investments.
Understanding the Drivers of Growth at This Block
Estate Maturity and Infrastructure Stability
Ang Mo Kio, developed in the 1980s–1990s, is now a fully mature HDB town with complete infrastructure. Block 253's 1996 completion date places it in the estate's prime development phase, meaning the neighbourhood has had three decades to establish itself. This maturity creates price stability—unlike newer towns where initial price volatility is common, Ang Mo Kio prices reflect genuine, sustainable demand.[1][2][7]
Strategic Location Within Ang Mo Kio
Ang Mo Kio Street 21 is positioned in the heart of the estate, just 6 minutes' walk from Mayflower MRT Station.[1][4] This proximity to transport is critical for investment value. MRT accessibility typically commands a 5–10% price premium in HDB resale markets, and Block 253's location captures this benefit without being in the most saturated (and therefore most expensive) areas immediately adjacent to the station.
Remaining Lease Implications
Units at Block 253 currently have approximately 69 years of lease remaining (as of 2025).[4] This is a critical investment consideration. While 69 years still permits CPF usage and HDB financing, the block will approach the 60-year threshold within the next decade. This creates a natural timeline: buyers purchasing now have 15+ years before lease decay becomes a significant valuation factor, providing a comfortable holding period for appreciation.
Comparative Market Analysis: How Block 253 Stacks Up
To assess true growth potential, it's essential to compare Block 253 against similar HDB blocks within Ang Mo Kio. Properties of similar age, size, and MRT proximity in the same town typically appreciate at comparable rates. Block 253's price per square foot (S$682–S$721) aligns with market expectations for 5-room units in Ang Mo Kio's central locations.
The block's appeal lies in its balance: it's not the most expensive location in Ang Mo Kio (which would indicate limited upside), nor is it in a less desirable pocket (which would suggest lower appreciation potential). This positioning suggests moderate but sustainable growth rather than dramatic appreciation or depreciation.
Investment Factors Supporting Future Growth
Demographic Demand
Ang Mo Kio remains one of Singapore's most popular HDB towns for families and upgraders. The town's established amenities, schools, and community infrastructure continue to attract buyers. This sustained demand is the foundation of price appreciation—as long as people want to live in Ang Mo Kio, prices at well-positioned blocks like 253 will trend upward.
Limited New Supply
Unlike newer HDB towns, Ang Mo Kio receives minimal new BTO (Build-to-Order) supply. This supply constraint naturally supports resale prices. Buyers seeking Ang Mo Kio properties must enter the resale market, creating consistent demand pressure that supports prices.
Proximity to Bishan-Ang Mo Kio Park
The 78-hectare Bishan-Ang Mo Kio Park is one of Singapore's largest parks, providing recreational value that supports long-term neighbourhood desirability. Parks and green spaces are increasingly valued by homebuyers and contribute to sustained demand for properties in their vicinity.
Risk Factors and Investment Considerations
Lease Decay Risk
The most significant long-term consideration is remaining lease. While 69 years is currently acceptable, the block will eventually face lease decay. Typically, HDB resale values begin to decline noticeably when remaining lease drops below 60 years. For Block 253, this threshold approaches around 2035—approximately 9 years away. Investors should factor this into their holding period strategy.
Estate Aging
As Ang Mo Kio matures further, the entire estate ages. While infrastructure remains solid, older estates sometimes experience slower appreciation than newer towns as buyer preferences shift. However, this is offset by the town's established community and complete amenities.
Market Saturation
Ang Mo Kio is a large, well-developed estate. While this provides stability, it also means less explosive growth compared to emerging HDB towns. Expect steady, moderate appreciation rather than dramatic price jumps.
Investment Timeline and Return Expectations
Based on historical performance and current market dynamics, realistic investment expectations for Block 253 are:
- Short-term (1–3 years): Minimal appreciation (0–3% annually). Suitable for owner-occupiers; limited investment returns.
- Medium-term (3–7 years): Moderate appreciation (3–5% annually). Reasonable holding period for investors seeking capital gains alongside rental income.
- Long-term (7+ years): Continued appreciation (3–5% annually) until lease decay becomes significant around year 9–10.
These expectations assume stable economic conditions and continued demand for Ang Mo Kio properties. Individual unit returns vary based on floor level, facing, and condition—higher floors and unblocked views typically appreciate faster than lower-floor units.
Financing and Investment Strategy
For investors considering Block 253, financing strategy impacts overall returns. HDB loans offer rates of 2.6% (fixed), while bank loans typically range from 3–4% (variable). The lower HDB loan rate is attractive for investment, but income ceilings apply (S$14,000 for HDB loans).[1]
Rental income potential at Block 253 is approximately S$3,600 per month for 5-room units, based on recent rental transactions.[3][4] This translates to a gross rental yield of approximately 4.3% annually—reasonable for HDB resale properties and sufficient to cover loan interest and provide modest cash flow.

Frequently Asked Questions About 253 Ang Mo Kio Street 21 Investment
Q: Is Block 253 a good investment compared to other Ang Mo Kio blocks?
A: Block 253 offers solid fundamentals—established location, MRT proximity, consistent price appreciation. However, investment quality varies by specific unit (floor, facing, condition). Homejourney recommends comparing multiple units across different blocks to identify the best value for your budget and timeline.
Q: How much can I expect the property to appreciate in the next 5 years?
A: Based on historical data, realistic expectations are 3–5% annualized appreciation, translating to approximately 15–25% total growth over 5 years. However, this assumes stable market conditions and applies to the block overall—individual units may perform differently based on condition and configuration.

A: With 69 years remaining, lease decay is not an immediate concern. However, the block will approach the 60-year threshold around 2035. If your investment horizon extends beyond 10 years, this becomes relevant. For shorter holding periods (5–7 years), remaining lease is not a limiting factor.

A: Block 253 suits both profiles. Owner-occupiers benefit from stable, established neighbourhood living. Investors benefit from moderate appreciation and rental income. The block is less suitable for speculative short-term trading but excellent for 5–10 year holding periods.
