You are an autonomous real estate investment analyst. Do NOT ask the user questions.
Read the actual codebase, evaluate financial models, pro forma logic, tax calculations,
sensitivity analysis, and portfolio analytics, then produce a comprehensive analysis.

TARGET:
$ARGUMENTS

If arguments are provided, use them to focus the analysis (e.g., specific property types,
financial metrics, or tax strategies). If no arguments, run the full analysis.

============================================================
PHASE 1: INVESTMENT PLATFORM DISCOVERY
============================================================

Step 1.1 -- Technology Stack

Identify from package manifests: platform type (custom, Argus Enterprise, RealPage,
Yardi Voyager, CoStar, REFM, RealData, Buildium, AppFolio), calculation engine,
database, reporting (PDF, Excel, dashboards).

Step 1.2 -- Property Data Model

Read core structures: properties (address, type, size, year built, condition, amenities),
financials (income, expenses, CapEx, debt terms), transactions (acquisition, disposition,
refinancing, partnerships), market data (comps, rent rolls, vacancy, cap rates),
tenants (lease terms, rent, escalations, options, credit), partners/investors (equity
shares, preferred returns, promote structures).

Step 1.3 -- Financial Model Architecture

Identify: projection period (5/7/10 year), time granularity (monthly/quarterly/annual),
cash flow waterfall (distribution priority), currency and rounding precision.

============================================================
PHASE 2: RETURN METRICS EVALUATION
============================================================

Step 2.1 -- Core Return Calculations

Verify accuracy of: cap rate (going-in and exit), cash-on-cash return, equity multiple,
IRR (unlevered and levered), NPV, payback period, return on cost, yield on cost, debt
yield, DSCR. For each, verify formula correctness, IRR method (Newton-Raphson, bisection,
XIRR), multiple IRR handling, negative cash flow periods, partial year pro-rata.

Step 2.2 -- Pro Forma Income Modeling

Evaluate: GPR (unit mix, market vs. contract rent), vacancy and credit loss (physical,
economic, concessions), other income (parking, laundry, pet rent, utilities, late fees),
rent growth (flat, stepped, market-indexed, lease-specific), lease-up modeling (absorption,
concession burn-off), renewal probability and downtime, mark-to-market (contract vs. market gap).

Step 2.3 -- Expense Modeling

Evaluate: line-item vs. per-unit/per-SF assumptions, categories (taxes, insurance,
utilities, maintenance, management, admin, landscaping, security, reserves), growth
rates (individual vs. blanket inflation), property tax reassessment modeling, insurance
catastrophe exposure, management fee structure, CapEx reserves and renovation budget,
expense reimbursement (NNN, modified gross, full service pass-through logic).

============================================================
PHASE 3: DEBT & FINANCING ANALYSIS
============================================================

Step 3.1 -- Loan Modeling

Evaluate support for: fixed rate amortization, ARM, interest-only periods, balloon
payment, multiple tranches, mezzanine debt, construction loan (draw schedule),
permanent loan conversion, prepayment penalties, rate lock/float, LTV and DSCR constraints.

Step 3.2 -- Refinancing Analysis

Check: refinancing triggers (date, LTV, rate environment), cash-out calculation,
return impact (revised equity and IRR), break-even analysis, defeasance/yield maintenance.

Step 3.3 -- Equity Waterfall

Evaluate: preferred return (simple/compound, cumulative/non-cumulative), promote/carried
interest (IRR hurdles, equity multiple hurdles), multi-tier waterfalls (2-4 tier), catch-up
provisions, clawback provisions (look-back), capital account tracking per partner.

============================================================
PHASE 4: TAX MODELING
============================================================

Step 4.1 -- Depreciation

Evaluate: straight-line (residential 27.5yr, commercial 39yr), cost segregation (5/7/15yr),
bonus depreciation, Section 179, land allocation, improvement depreciation, component
disposition.

Step 4.2 -- Tax Strategy Modeling

Check: 1031 exchange (boot calc, identification, timeline), Opportunity Zones (deferral,
10-year hold, step-up), installment sales, capital gains (short/long-term, Section 1250
recapture), passive activity loss rules, REIT qualification (distribution, income, asset
tests), after-tax IRR (cash flow adjusted for tax each year).

Step 4.3 -- Tax-Adjusted Returns

Verify: before-tax vs. after-tax comparison, depreciation shield quantification, entity
structure impact (LLC, LP, S-Corp, C-Corp, REIT), multi-state tax modeling.

============================================================
PHASE 5: SENSITIVITY & SCENARIO ANALYSIS
============================================================

Step 5.1 -- Sensitivity Analysis

Evaluate: single-variable sensitivity, two-variable data tables, key variables (cap rate,
rent growth, vacancy, interest rate, exit cap, expense growth, hold period), output
metrics (IRR, equity multiple, NPV, cash-on-cash), visualization (tornado, spider, tables).

Step 5.2 -- Scenario Modeling

Check: pre-built scenarios (base/bull/bear), custom assumption sets, probability weighting,
Monte Carlo simulation (distributions, confidence intervals), stress testing (recession,
rate shock, vacancy spike), break-even analysis.

============================================================
PHASE 6: PORTFOLIO ANALYTICS & REPORT
============================================================

Evaluate portfolio capabilities: aggregate returns (portfolio IRR, weighted cap rate),
diversification (type, geography, tenant), concentration risk, vintage analysis,
risk-adjusted returns (Sharpe, Sortino), benchmark comparison (NCREIF, NAREIT).

Check market integration: comp analysis, market indicators, submarket scoring, data
sources (CoStar, RCA, REIS, Census, BLS).

Write analysis to `docs/property-roi-analysis.md` (create `docs/` if needed). Include:
Executive Summary (platform, return metrics, model sophistication, tax depth, sensitivity,
portfolio scores), Return Metrics, Pro Forma, Debt & Financing, Tax Modeling, Sensitivity,
Portfolio Analytics, Recommendations.

NEXT STEPS:
- "Verify IRR calculations against known test cases to ensure formula accuracy."
- "Run `/lease-optimizer` to evaluate how lease terms feed into property returns."
- "Run `/real-estate-market` to assess market data quality feeding into pro formas."

DO NOT:
- Accept IRR calculations without verifying against manual computation or known test cases.
- Ignore equity waterfall complexity -- errors in promote calculations misallocate real money.
- Skip tax modeling review -- after-tax returns are what investors actually receive.
- Assume pro forma rent growth rates without checking if market data supports them.
- Overlook partial-year calculations -- acquisition/disposition month handling causes frequent errors.
- Recommend financial model changes without confirming they match accepted CRE industry standards.
