UNDERWRITING METHODOLOGY

Deterministic Mathematical Underwriting Methodology

AV Property Intelligence replaces speculative broker sentiment with pure mathematical determinism. Here is the complete architectural calculus behind our spatial loading unmasker, multi-tier tax waterfalls, and compounding operational financial models.

Core Engine: 100% Deterministic Financial Modeling • Zero Subjective Estimates

1. Spatial Efficiency

Extracting net usable RERA carpet area from inflated super built-up claims to reveal the true cost per livable square foot.

2. Statutory Tax Waterfall

Calculating every state-specific revenue charge (Article 25 Stamp Duty, Metro Cess, GST, and Ancillaries) before token issuance.

3. Carrying Cost Arbitrage

Quantifying Pre-EMI interest, subvention risks, and construction delay costs under RERA Section 18 reciprocal mandates.

4. Residual Land Equity

Verifying Undivided Share of Land (UDS) mathematical entitlement to protect long-term 40-year redevelopment equity.

01.Carpet Loading Factor & True Living Rate Calculus

Traditional brokers quote property prices on Super Built-up Area (SBA). This headline number artificially deflates the perceived per-square-foot rate. Our engine executes a two-step mathematical extraction:

FORMULA A: SPATIAL LOADING FACTOR (%)

Loading % = [ (Super Built-up Area - RERA Carpet Area) / Super Built-up Area ] × 100

Example: 2,100 sq.ft SBA with 1,420 sq.ft Carpet = [ (2100 - 1420) / 2100 ] × 100 = 32.38% Loading Factor

FORMULA B: TRUE USABLE LIVING RATE (₹/SQ.FT)

True Living Rate = Base Property Consideration / RERA Carpet Area

Example: ₹2.40 Cr on 1,420 sq.ft Carpet = ₹16,901/sq.ft (vs quoted super rate of ₹11,428/sq.ft, revealing a +47.9% living space markup).

02.The 25-Year Compounding Phantom Maintenance Formula

Because apartment societies bill maintenance on Super Built-up Area rather than carpet space, buyers pay recurring monthly fees on space they cannot inhabit. Our simulator models this cumulative cash drag using geometric compounding:

FORMULA C: COMPACTED LIFETIME PHANTOM MAINTENANCE (M_total)

M_total = Σ [ (Phantom Sqft) × R₀ × (1 + g)^(t - 1) × 12 ] for t = 1 to N

Where Phantom Sqft = (SBA - Carpet), R₀ = initial monthly rate per sq.ft, g = annual inflation rate (default 6%), and N = holding horizon (years).
