Comprehensive Investment Analysis

1. Rental Income Potential

  • Current Contract Rent: The unit is currently tenanted at ¥75,000 per month (approximately $473 USD), producing an annual gross rental income of ¥900,000 (approximately $5,672 USD).
  • Market Context: Single-unit 1K condominiums (20–25 m²) in the Nishi-Kasai and Kasai areas typically attract steady tenant demand from young professionals and commuting workers due to direct Tozai Line access into central Tokyo business districts (Otemachi, Nihombashi).
  • Factors Affecting Rental Rates: The presence of an elevator supports tenant accessibility on the 3rd floor. However, the absence of a main entrance auto-lock system and the 1980 construction year constrain upside rental growth compared to modern, secure urban developments.

2. Investment ROI Analysis

Calculated Gross Yield: 7.40% Calculated Net Yield: 5.60%

  • Operating Expense Breakdown:
    • Building Management Fee (管理費): ¥15,000/month (approximately $95 USD)
    • Repair Reserve Fund (修繕積立金): ¥3,000/month (approximately $19 USD)
    • Property Management Fee (管理手数料, 5.5%): ¥4,125/month (approximately $26 USD)
    • Vacancy Allowance (5%): ¥3,750/month (approximately $24 USD)
    • Property Tax (固定資産税): ¥10,167/month (¥122,000/year; approximately $769 USD/year)
    • Total Recurring Expenses: ¥36,042/month (approximately $227 USD/month; ¥432,500/year), representing a 48.1% operating expense ratio relative to gross rental income.
  • Acquisition Transaction Costs (All-Cash): ¥1,075,600 (approximately $6,778 USD; 8.82% of asking price), comprising Agent Commission (¥468,600), Real Estate Acquisition Tax (¥256,200), Registration Tax (¥170,800), Stamp Duty (¥20,000), Judicial Scrivener Fee (¥80,000), and Initial Insurance (¥80,000). Total cash required for all-cash purchase is ¥13,275,600 (approximately $83,663 USD).
  • Transaction Mode: Standard Brokerage (媒介). Standard statutory commission applies.
  • Payback Period & Cash Flow: Net Operating Income (NOI) is ¥467,500/year (approximately $2,946 USD). On an all-cash basis, simple equity payback is approximately 28.4 years.

3. Property Desirability to Renters

  • Target Demographic: Single young professionals, commuters, and university students seeking affordable housing within standard walking distance of Tozai Line transit links. Demographic projections for Tokyo indicate sustained growth in single-person households (+39.3% for single elderly by 2040 and stable single 25–39 cohorts).
  • Location Advantages: Positioned 9 minutes (720m) on foot from Nishi-Kasai Station and 14 minutes from Kasai Station. Both stations sit on the Tokyo Metro Tozai Line, offering express commuting to major employment centers. Local living infrastructure is well-developed with retail, dining, and daily conveniences (e.g., Yukawa 商会 at 30m, Seven-Eleven at 138m) nearby.
  • Demand-Driver Institutions:
    • Universities: 葛西南高校 (educational institution) is located 1,023m away. Note: No high-volume university with student enrollment figures is present in the immediate POI radius, making transit accessibility the primary driver of single-occupancy rental demand.
  • Unit Features: 23.80 m² 1K layout with balcony (3.10 m²), city gas supply, municipal water/sewer, and elevator access on the 3rd floor of a 6-story RC structure.

4. Market Context

  • Pricing Breakdown: The asking price of ¥12,200,000 translates to ¥512,605/m² (approximately $3,230 USD/m²).
  • Municipality Comparative Positioning (Edogawa-Ku):
    • MLIT observed transaction prices for Edogawa-ku over the last 4 quarters indicate a median unit price of ¥707,692/m² (P25: ¥582,500/m²; P75: ¥875,481/m²).
    • The subject property's unit price of ¥512,605/m² sits below the P25 band for Edogawa-ku, reflecting a noticeable discount driven by building age (45 years) and pre-1981 seismic code construction.
    • Estimated based on general market knowledge: Unit prices for 40+ year-old 1K condos in Edogawa-ku typically trade in the ¥450,000–¥550,000/m² range.

5. Risk Assessment

  • Seismic Classification & Pre-1981 Warning:

⚠️ OLD SEISMIC STANDARD (旧耐震基準) WARNING

  • Built in October 1980 (building age: 45 years), this structure predates the June 1, 1981 seismic code revision.

  • Financing Impact: Most standard commercial Japanese banks restrict or decline mortgage financing for pre-1981 buildings due to shortened statutory useful life.

  • Insurance Impact: Ineligible for the 10% 建築年割引 (building year discount) under earthquake insurance (地震保険). Premium discounts require a 耐震基準適合証明書 (seismic compliance certificate) derived from a formal seismic evaluation.

  • Resale Risk: The buyer pool upon exit is primarily restricted to cash investors or buyers utilizing specialized non-conforming lenders.

  • Seismic Probability × Structure Pairing: J-SHIS mapping indicates a 30-year probability of 92.6% for ground shaking reaching JMA Intensity 6-Lower or higher (震度6弱以上) at this mesh location (High Tier, ≥ 26%). This high ground-motion hazard compounds with the pre-1981 structural code, reinforcing the need for adequate fire and earthquake insurance coverage.

  • Multi-Dimensional Building Age Factors:

    • Major Repair Cycle (大規模修繕): At 45 years old, the building has passed multiple 12–15 year major repair cycles. With only 26 total units in the building, individual owners face concentrated exposure to potential reserve fund adjustments or special assessments if capital reserves are underfunded.
    • Equipment Lifecycle: System overhauls for common area plumbing, electrical distribution, and elevator infrastructure represent ongoing CapEx risks for older RC structures.
    • Tenant Appeal: Pre-1990 unit layouts lacking auto-lock entrances may experience higher tenant turnover compared to newer security-equipped properties.
  • Demolition & Asbestos (ACM) Cost Guidance:

    • Demolition Cost Benchmark: Standard RC structure demolition in urban Tokyo ranges from ¥25,000 to ¥40,000 per m² of total floor area.
    • Asbestos Risk (Pre-1990 Build): Constructed in 1980, asbestos-containing materials (ACM) may be present in pipe insulation, fireproofing, or ceiling tiles.
    • ACM Removal Cost Estimate: Per MLIT guidelines for buildings ≤300m², asbestos removal costs range from ¥20,000–85,000/m² plus inspection fees of ¥100,000–500,000. Asbestos abatement cost: unquantified – survey required prior to major structural alterations or demolition.
  • Natural Disaster Hazards:

    • Flood Risk (River Overflow): Medium risk; potential inundation depth of 0.5m–1.5m (GSI hazard map). The subject unit is located on the 3rd floor, significantly mitigating direct water damage risk to exclusive floor area.
    • Storm Surge (Typhoon): High risk zone with maximum potential inundation depth of 3.5m (range 3.0m–5.0m). Ground-floor and common-area infrastructure remain exposed during extreme surge events.
    • Tsunami / Landslide / Internal Flooding: None detected.
    • Disaster Framing & Insurance: BOJ research indicates flood zone discounts average approximately −1.1% per meter of depth. Fire insurance (火災保険) with flood/water damage coverage is essential for common area protection.
  • Occupancy & Vacancy Risk: The unit is currently tenanted (賃貸中) at ¥75,000/month, providing immediate rental cash flow upon acquisition without initial leasing downtime.

6. Cost-Approach Valuation (積算価格)

  • Status: Cost-approach valuation is currently unavailable for this listing due to unimported land share coefficient data.
  • Land Value & Collateral Framing: Japanese institutional lenders evaluate pre-1981 RC buildings (47-year legal depreciation life) as having near-zero structural asset value for collateral purposes (45 years old = 2 years remaining statutory life). Consequently, bank collateral value relies almost entirely on land share value (路線価 basis).

7. Property Assessment

Property Assessment: Neutral

Primary Reason: The property offers immediate cash flow with a 7.40% gross yield (5.60% net) in an accessible Tokyo commuting hub, offset by structural risks associated with a 45-year-old pre-1981 building and elevated storm surge/seismic hazards.

Supporting Factors:

  • Tenanted status at ¥75,000/month provides immediate income continuity with strong transit access to Nishi-Kasai Station (9-minute walk).
  • High recurring operating expense ratio (48.1% of gross rent, including ¥15,000/month building management fee) compresses net returns.
  • Pre-1981 RC construction and a 92.6% 30-year P(≥震度6弱) ground motion probability limit financing options and increase long-term CapEx exposure across a small 26-unit association.

Hypothetical Financing Scenarios

The following scenarios illustrate how different investor financing profiles impact leverage and cash returns based on the asking price of ¥12,200,000 and total acquisition cash requirements of ¥13,275,600.

Scenario Comparison Summary

Note: Cash-on-Cash Return is calculated as Net Cash Flow divided by Total Cash Invested (Equity Down Payment + ¥1,075,600 Acquisition Costs).

Detailed Breakdown: User-Specified Financing Plan

  • Buyer Tier Context: Tier A / Tier B investor with local financing access.
  • Purchase Price: ¥12,200,000 (approximately $76,884 USD)
  • Down Payment (40%): ¥4,880,000 (approximately $30,754 USD)
  • Loan Amount (60% LTV): ¥7,320,000 (approximately $46,131 USD)
  • Loan Terms: 2.15% annual interest rate, 30-year term, Equal Principal Repayment (元金均等返済).
  • Repayment Schedule: Annual principal repayment of ¥244,000 plus declining annual interest (Year 1 interest: ¥154,829). Total Year 1 debt service is ¥398,829 (approximately $2,513 USD).
  • Cash Flow: Annual NOI of ¥467,500 minus Year 1 debt service of ¥398,829 leaves an estimated Year 1 pre-tax net cash flow of ¥68,671 (approximately $433 USD).
  • Total Initial Cash Required: ¥5,955,600 (Down Payment ¥4,880,000 + Acquisition Costs ¥1,075,600; approximately $37,532 USD).

What This Analysis Could Not Determine

1. Data Not Available

  • Land Area & Land Share (敷地権割合): Specific land area and unit ownership share ratio were not detailed in the listing record, preventing exact calculation of the cost-approach value (積算価格) and land collateral basis.
  • Management Association Reserves (修繕積立金残高): Total accumulated repair reserve funds held by the 26-unit management association were absent.
  • Building Permit Confirmation Date (建築確認日時): Only construction completion (October 1980) was available; exact permit confirmation date was not stated.

2. Assumption-Dependent Figures

  • Property Tax (固定資産税): Estimated at ¥122,000/year based on user-provided inputs; subject to municipal assessment notices (固定資産税課税明細書).
  • Property Management Commission: Modeled at 5.5% of gross rent (¥4,125/month) per user assumptions.
  • Vacancy Rate: Modeled at a baseline 5.0% allowance (¥3,750/month).
  • Earthquake Insurance Premiums: Estimated at ¥0 in baseline opex; individual quotes depend on structure evaluation and coverage limits.

3. Questions for a Licensed Professional

  • 宅地建物取引士 (Real Estate Transaction Specialist): Request formal confirmation of road access compliance (接道状況), non-rebuildable status (再建築不可 check), and common area usage rules outlined in the Important Points Explanation (重要事項説明書).
  • 不動産鑑定士 (Real Estate Appraiser): Evaluate land share value relative to local 路線価 (rosenka) to determine collateral coverage for financing or future resale.
  • 税理士 (Tax Accountant): Confirm qualifying depreciation schedules (47-year RC legal life; 2 remaining years under standard statutory rules) and non-resident withholding tax obligations on rental income and eventual capital gains.
  • 司法書士 (Judicial Scrivener): Review title registration records (登記簿謄本) to verify clear ownership rights, absence of encumbrances, and precise acquisition tax assessments.
