CondoWatch 10-Point Buyer Audit™ Methodology
Most property portals treat every new launch like a 5-star brochure. We built a deterministic, 50-Mark empirical evaluation engine that tests every Singapore condominium and Executive Condominium across 10 objective investment pillars — transparently documenting both marks earned and why marks dropped.
🔍 Why We Built the 10-Point Buyer Audit™
Buying a $1.8M to $5M+ Singapore residential property is one of the largest capital allocation decisions a household will make. Our methodology is governed by four strict institutional principles:
1. Accounting for Dropped Marks
Every project starts from a theoretical 50-mark ceiling. Whenever a project drops a star (e.g. unsheltered MRT walk, 80% car park ratio, or boutique maintenance sharing), our engine explicitly logs the trade-off in the "Why Marks Dropped" audit drawer.
2. Segment-Aware Realism
A District 09 luxury condo and a District 25 Executive Condominium have completely different exit buyers. Our engine dynamically calibrates rental yield benchmarks, GLS land breakeven costs, and resale buyer pools by market segment (CCR, RCR, OCR, and EC).
3. Layman-Friendly Transparency
We translate raw urban planning numbers into everyday buyer impact — converting Plot Ratios and Gross Floor Area into land share per unit (sq ft), open landscape percentage, and actual walking minutes.
4. Cross-Verified Government Data
Every score is computed algorithmically from URA REALIS caveats, LTA transit coordinates, MOE Phase 2C balloting records, URA/HDB GLS tender awards, and HomeWatch.sg's empirical HDB & retail POI registries.
🏆 The 50-Mark Grading Scale & Tier Classification
Each of the 10 pillars is scored from 2★ to 5★ (worth up to 5 marks per pillar). Every mark equals exactly 2.0% of the total 50-Mark score:
Sweeps almost all 10 fundamentals — combining doorstep MRT, 1km elite school priority, resort land scale, and strong exit catalysts.
Strong across core pillars with minor, well-compensated trade-offs (e.g. 8-minute walk to MRT or 80% transit-zone parking provision).
Delivers dependable livability or niche strengths (such as freehold boutique privacy) while requiring buyers to accept specific location or scale trade-offs.
Tailored for buyers prioritizing a specific lifestyle (e.g. secluded landed/waterfront enclaves or ultra-boutique apartments) over mass-market transit or school metrics.
📋 The 10 Empirical Pillars & Scoring Rubrics
Below is the exact deterministic rubric used by audit_engine.py to score every development on CondoWatch.sg:
1 🚇 Walk to MRT (Transit Accessibility)
Source: LTA Station Coordinates & Developer Site PlansCalculates great-circle haversine distance to 160+ operating and upcoming MRT stations, multiplied by a 1.18× Singapore pedestrian street-grid winding factor at an empirical walking pace of 80 metres per minute (or verified sheltered linkway distance).
| ★★★★★ (5/5) | ≤ 5 min walk (~400m) or direct sheltered integrated linkway to MRT station entrance. |
|---|---|
| ★★★★☆ (4/5) | 6 – 9 min walk (450m – 750m); comfortable daily walk without needing feeder bus transfers. |
| ★★★☆☆ (3/5) | 10 – 14 min walk (800m – 1.15km); walkable in cool weather, best paired with feeder bus or cycling. |
| ★★☆☆☆ (2/5) | ≥ 15 min walk (> 1.2km); relies primarily on feeder bus, shuttle service, or private vehicle. |
2 🏫 Primary Schools (1km MOE Phase 2C Priority)
Source: MOE School Registry & HomeWatch.sg P1 Balloting DataIn Singapore, living within 1.0km of a popular primary school grants Citizen and PR families priority admission during MOE Phase 2C and 2C(S) — one of the strongest drivers of resale price resilience. We cross-reference all 180+ primary schools against our Elite School directory (9 GEP Centres, 15 SAP Schools, and 12 MOE Phase 2C Pilot Anchors) and historical balloting ratios on HomeWatch.sg.
| ★★★★★ (5/5) | ≥ 1 Elite / GEP / SAP / Premier Primary School within 1.0km OR ≥ 3 MOE Primary Schools within 1.0km. |
|---|---|
| ★★★★☆ (4/5) | 1 – 2 MOE Primary Schools within 1.0km (verified Phase 2C priority catchment). |
| ★★★☆☆ (3/5) | 0 schools within 1.0km, but ≥ 1 school within 1.0 – 2.0km (secondary Phase 2C distance band). |
| ★★☆☆☆ (2/5) | 0 primary schools within 2.0km (commercial/CBD or island resort zone). |
3 🏢 Estate Size & Facilities (Scale & Land Share)
Source: URA Master Plan Plot Ratio & Cadastral Land RegistryEvaluates total residential unit count, land site area (strictly in sq ft and sqm), URA Gross Plot Ratio (GPR), open landscape & facilities coverage percentage, and land share per unit (sq ft/unit). Larger estates enjoy full resort facilities (50m lap pools, tennis courts, grand clubhouses), higher transaction frequency (bank valuation support), and lower monthly MCST maintenance share per household.
| ★★★★★ (5/5) | Mega / Full-Resort Scale (≥ 450 units) or generous land footprint with comprehensive facilities and broad MCST maintenance sharing. |
|---|---|
| ★★★★☆ (4/5) | Mid-Sized Development (250 – 449 units); balanced facilities and healthy resale transaction volume. |
| ★★★☆☆ (3/5) | Boutique Enclave (100 – 249 units); high privacy, though monthly upkeep is shared across a smaller owner base. |
| ★★☆☆☆ (2/5) | Micro-Boutique (< 100 units); exclusive low-density living, but infrequent resale caveats and higher per-unit sinking fund share. |
4 📜 Lease Freshness & Tenure Protection
Source: SLA Land Tenure & URA GLS Lease CommencementEvaluates whether a development is Freehold / 999-Year (Estate in Perpetuity) or 99-Year Leasehold, and calculates the remaining lease life at exit. Fresh leases (≥90 years remaining) ensure future resale buyers qualify for maximum 30-year bank mortgages and unrestricted CPF Ordinary Account usage under Bala's Curve rules.
| ★★★★★ (5/5) | Freehold / 999-Year (zero lease decay) OR Brand-New 99-Year Leasehold (≥ 95 years remaining). |
|---|---|
| ★★★★☆ (4/5) | Young 99-Year Leasehold (85 – 94 years remaining); full loan tenure and CPF eligibility for next buyer. |
| ★★★☆☆ (3/5) | Seasoned 99-Year Leasehold (75 – 84 years remaining); approaching age where younger buyers monitor lease decay. |
| ★★☆☆☆ (2/5) | Aging Leasehold (< 75 years remaining); potential CPF withdrawal and loan-to-value (LTV) restrictions for younger buyers. |
5 💰 Rental Cash Return (Gross District Yield)
Source: URA Rental Contracts & District Median BenchmarksMeasures empirical gross annual rental yield across Singapore's 28 Postal Districts. Our engine clearly explains that Core Central Region (CCR D09/D10/D11) properties naturally yield ~3.0%–3.1% because prime central land values are higher (prioritizing wealth preservation and corporate expat tenant quality), whereas OCR / RCR regional employment hubs achieve higher 3.5%–3.85% cash yields.
| ★★★★★ (5/5) | ≥ 3.80% Gross Rental Yield (High-yield regional employment hubs such as Woodlands D25 & Yishun/Sembawang D27). |
|---|---|
| ★★★★☆ (4/5) | 3.15% – 3.79% Gross Rental Yield (Strong RCR city-fringe and OCR suburban tenant catchments). |
| ★★★☆☆ (3/5) | < 3.15% Gross Rental Yield (Prime CCR D09/D10/D11 luxury residences where capital preservation outweighs cash yield percentage). |
6 🏠 Future Resale Buyer Pool (Segment-Aware Dual Track)
Source: HomeWatch.sg 10,471 HDB MOP DB + 131,793 URA Private CaveatsWho will buy your condo when you sell 3–5 years after TOP? Because a $3.5M Orchard condo and a $1.9M Tampines condo have completely different buyers, Pillar 6 operates on a Segment-Aware Dual-Track Engine:
Evaluates the 2.0km HDB Upgrader Pool (4-Room, 5-Room & Executive flats reaching their 5-year Minimum Occupation Period at MOP Year ≥ TOP Year − 2) plus verified $1M+ HDB resale transactions via HomeWatch.sg.
Since standard 5-year BTO upgraders cannot afford $3M–$5M+ CCR quantum, Track B evaluates 3-Year District URA Private Resale & Sub-Sale Volume (measuring private condo upgraders & landed downsizers) alongside surrounding $1M+ high-equity HDB sellers and 1km Phase 2C school families.
| ★★★★★ (5/5) | RCR/OCR/EC: ≥ 3,000 verified 4R/5R/Exec flats reaching MOP within 2km in the exit window. |
|---|---|
| ★★★★☆ (4/5) | RCR/OCR: 1,200 – 2,999 fresh MOP flats (or ≥ 150 $1M+ HDB sales in mature estates). CCR/Central: ≥ 1,100 verified 3-year URA private resale deals in the district (e.g. D10: 3,852 deals; D09: 2,420 deals; D11: 1,677 deals) + $1M+ HDB / elite school family demand (drops 1 mark only for higher CCR lump-sum capital barrier). |
| ★★★☆☆ (3/5) | RCR/OCR: 500 – 1,199 fresh MOP flats or ≥ 2,500 established 4R/5R flats. Central CBD (D01/D02/D07): 400 – 1,099 3-year district URA private resales (investor-heavy compact unit catchments). |
| ★★☆☆☆ (2/5) | < 500 MOP flats (suburban) or < 400 3-year URA private resales (ultra-niche civic core enclave). |
7 📍 URA Master Plan Growth Catalyst
Source: URA Master Plan Transformation NodesMeasures spatial proximity to Singapore's 11 flagship national transformation corridors: Jurong Lake District (2nd CBD), Greater Southern Waterfront, HealthCity Novena & North-South Corridor, Woodlands Regional Centre & JB-SG RTS Link, Punggol Digital District, Bayshore & East Coast Long Island, Upper Thomson/Springleaf Green Corridor, Lentor Hills, Marina Bay Financial Expansion, One-North Innovation Hub, and Changi East T5 Mega Hub.
| ★★★★★ (5/5) | Inside Core Transformation Radius (≤ 600m – 1,200m node core); direct beneficiary of new MRT interchanges, commercial towers, and public realm upgrades. |
|---|---|
| ★★★★☆ (4/5) | Secondary Spillover Buffer (≤ 1.2km from node center); enjoys tenant and infrastructure spillover. |
| ★★★☆☆ (3/5) | Regional Buffer (1.2km – 2.0km); benefits from broader regional connectivity. |
| ★★☆☆☆ (2/5) | Mature Non-Growth Zone (> 2.0km); relies on organic inflation or private en-blocs rather than state infrastructure catalysts. |
8 🏗️ Future Land Supply & Benchmark Resets
Source: 73 Verified URA & HDB GLS Tenders + En-BlocsAnalyzes all confirmed Government Land Sales (GLS) and collective sale tenders within a 2.0km radius (View GLS Land Sales Directory). When a neighbouring GLS parcel is awarded at a higher land rate ($ PSF PPR) than your project, future competing launches must launch at higher indicative prices — creating a positive valuation umbrella for early buyers. Conversely, excessive unlaunched plots at flat land prices create supply overhang risk.
| ★★★★★ (5/5) | Confirmed Positive Land Benchmark Reset (+15% to +60%+ higher $ PSF PPR nearby) without excessive supply overhang. |
|---|---|
| ★★★★☆ (4/5) | 1 – 3 nearby GLS parcels providing healthy progressive price discovery and controlled supply. |
| ★★★☆☆ (3/5) | 0 state GLS plots within 2km (fully built-up mature precinct relying on organic resale/en-bloc comps) OR 4+ plots with moderate upcoming supply. |
| ★★☆☆☆ (2/5) | ≥ 3 competing GLS plots totaling ≥ 2,500 units within 2km without upward land price resets (supply competition watchout at TOP). |
9 🛒 Nearby Malls & Supermarkets (Daily Convenience)
Source: HomeWatch.sg Retail Registry (120 Malls & 605 Supermarkets)
Evaluates walking distance (using the 1.18× pedestrian winding factor) to 120 major shopping malls and 605 supermarkets (prioritizing full-service chains: FairPrice, FairPrice Finest, FairPrice Xtra, Cold Storage, CS Fresh, Sheng Siong, Giant, Don Don Donki, Little Farms, Meidi-Ya, Prime, and U Stars), plus detection of on-site commercial/retail podiums in mixed-use developments.
| ★★★★★ (5/5) | On-site Integrated Retail/Supermarket Podium OR Major Mall ≤ 650m & Supermarket ≤ 600m (or Major Mall ≤ 450m). |
|---|---|
| ★★★★☆ (4/5) | Walkable Supermarket (≤ 850m) & Lifestyle Mall (≤ 1.35km), or Major Mall within 850m. |
| ★★★☆☆ (3/5) | Supermarket within 1.35km OR Shopping Mall within 2.0km (short feeder bus, 1 MRT stop, or 3-min drive for weekly groceries). |
| ★★☆☆☆ (2/5) | Secluded Residential Enclave (> 1.35km to grocer & > 2.0km to mall); relies on driving or grocery delivery. |
10 🚗 Car Park Lots & EV Provision
Source: URA Written Permission Site Plans & LTA Car-Lite Zones
Under post-2019 LTA/URA Range-Based Parking Provision Standards (RPPS), developments inside Transit Priority Corridors and Car-Lite Precincts are permitted to provide fewer than 1 car park lot per unit. We audit the residential lot-to-unit ratio (%) and LTA-mandated EV charging bays so car-owning families know whether they face balloting risk. For unlaunched GLS previews pending architectural layout approval, our engine transparently labels the URA zone estimate (Est. Pending Site Plan).
| ★★★★★ (5/5) | Full 1:1+ Residential Provision (≥ 100% ratio) or private car porch (≥ 2 lots/home). Zero balloting risk for first-car owners. |
|---|---|
| ★★★★☆ (4/5) | High Modern URA Provision (80% – 99% ratio + EV bays). Comfortably serves all 2BR–5BR family drivers (since a portion of 1BR/2BR investors do not own cars), though 2nd-car seasonal lots are limited. |
| ★★★☆☆ (3/5) | Moderate LTA Car-Lite Provision (60% – 79% ratio). Developers prioritize 3BR–5BR family units for first-lot allocation; 1BR/2BR buyers may face balloting. |
| ★★☆☆☆ (2/5) | Strict CBD / Integrated Car-Lite Zone (< 60% ratio). Built for MRT-first urbanites; car owners must confirm developer bedroom-tier parking priority prior to booking. |
📐 Segment-Calibrated GLS Land Breakeven Model
To help buyers evaluate whether a new launch's indicative pricing offers a fair margin of safety above the developer's land cost, our pricing engine (gls_pricing.py) models construction, financing, marketing, and net saleable efficiency across 5 distinct property segments:
| Market Segment | Construction Cost (PSF GFA) | Financing, Legal & Overheads | Net Saleable Efficiency | Typical Developer Margin | Empirical Calibration Benchmark |
|---|---|---|---|---|---|
| Executive Condo (EC) | $530 PSF | 6% land load + $50 PSF | 90% | 10% – 18% | $1,650 – $1,850 PSF (e.g. Aurelle of Tampines) |
| Outside Central (OCR) | $540 PSF | 7% land load + $100 PSF | 90% | 10% – 18% | $2,150 – $2,450 PSF (e.g. Lucerne Grand) |
| Rest of Central (RCR) | $620 PSF | 7% land load + $120 PSF | 90% | 12% – 20% | $2,450 – $2,900 PSF (e.g. Thomson Reserve, Emerald of Katong) |
| Core Central (CCR) | $750 PSF | 8% land load + $150 PSF | 88% | 15% – 22% | $2,950 – $3,500+ PSF (e.g. River Green, The Serra) |
| Mixed-Use / ITH | +$50 PSF add-on | Segment baseline | 85% | Segment baseline | Integrated Transport Hubs & Commercial Podiums |
🧭 3-Phase Strategic Exit Roadmap Methodology
Every 10-Point Buyer Audit™ concludes with a customized Holding & Liquidity Horizon mapped to the project's estimated Temporary Occupation Permit (TOP) year:
Phase 1: Construction & SSD Runway
Tracks the 3-Year Seller's Stamp Duty (SSD) holding period (12% Yr 1, 8% Yr 2, 4% Yr 3) alongside Progressive Payment Scheme (PPS) cashflow staging — or the Deferred Payment Scheme (DPS) for grandfathered ECs.
Phase 2: TOP Handover & 12-Month DLP
Covers key collection, the 12-month developer Defect Liability Period (DLP), initial tenant leasing stabilization, and the earliest sub-sale window once the 3-year SSD lock-in expires.
Phase 3: Primary Liquidity Window
For private condos, 2–4 years post-TOP is the historical sweet spot: defect checks are settled, landscaping is matured, and ~92+ years of remaining lease grants resale buyers maximum 30-year loans and full CPF usage. For ECs, Phase 3 maps the Year 5 MOP (Citizen/PR resale) and Year 10 Full Privatization windows.
