🟢search_properties(city, locality, propertyType, bedrooms, minPrice, ...)
Search residential property listings in Coimbatore and Chennai, Tamil Nadu. Use when the user names a locality, price band, BHK, or transaction type in either city. Returns sanitized listing cards with handoff URLs and a per-listing verified flag; never returns seller contact details. Out-of-scope cities return supported=false + supportedCities + scopeMessage — surface the scopeMessage to the user.

}🟢get_locality_insights(locality, city)
Get aggregated insights for a Coimbatore or Chennai locality: avg price, supply count, demand pulse, livability/investment grade, highlights, watchouts, monthly priceTrends, and strengthTags. Use when the user asks "what is X locality like" about a neighborhood in either city. Out-of-scope cities return supported=false; surface the scopeMessage to the user. Always surface the disclaimer field when returning livability or investment grade.

}🟢compare_localities(city, localities, propertyType)
Compare 2–3 Coimbatore or Chennai localities side-by-side: price trends, livability, investment grade, strengths, and watchouts. Use when the user asks "X vs Y" or "which is better between X and Y for buying/renting" about neighborhoods in these cities. Out-of-scope cities return supported=false; surface the scopeMessage to the user. For comparing specific LISTINGS by ID, use compare_properties instead.

}🟢calculate_home_affordability(propertyValue, loanAmount, interestRatePercent, tenureYears)
Estimate the monthly home-loan EMI / monthly payment in India — a home-loan calculator. Deterministic math; not advice or a loan-approval claim. Two modes: pass propertyValue (80% LTV assumed) OR loanAmount for a specific loan (e.g. "₹50 lakh loan"). Use for "what would my EMI be" / "monthly payment on …". The response `assumptionNote` states the basis in plain words. Always surface the disclaimer field.

}🟢simulate_loan_prepayment(outstandingPrincipal, remainingTenureYears, annualRatePercent, prepaymentAmount, recurringAnnualAmount, ...)
Simulate prepaying / repaying an Indian home loan early. Pure deterministic math — no advice, no loan-approval claim. Use for "should I prepay", "early/part/lump-sum repayment", "pay extra each month", "reduce EMI or tenure", "interest saved", or foreclosure. Modes: one-time, recurring yearly, or a fixed extra every month (recurring_monthly). Compares reduce_tenure (keep EMI, finish early) vs reduce_emi (keep tenure, lower EMI). Always surface the disclaimer field.

}🟢compare_balance_transfer(outstandingPrincipal, currentRatePercent, newRatePercent, remainingTenureYears, processingFeePct, ...)
Compare staying on your current home loan vs. transferring (refinancing) to a lower rate. Pure deterministic math — no advice, no loan-approval claim. Use when the user asks "should I switch lenders / transfer my loan / refinance". Returns new EMI, interest saved over the remaining tenure, switching cost, net saving, and the breakeven month. Always surface the disclaimer field.

}🟢optimize_home_loan_tax_regime(annualIncome, isSalaried, homeLoanInterest, homeLoanPrincipal, propertyType, ...)
Compare a home-loan borrower's income tax under the OLD vs NEW regime (FY2026-27) and recommend which regime saves more income tax. Pure deterministic slab math — not tax advice. Use when the user asks "old or new tax regime", "home-loan tax benefit", or "section 80C / 24(b) deduction". Models §24(b) interest + §80C principal (+ joint-loan doubling); the response lists benefits it does NOT model (capital gains, HRA, etc.). Always surface the disclaimer field.

}🟢estimate_stamp_duty_and_registration(propertyValue, state, city, localBody, firstSale, ...)
Estimate Indian state stamp duty + registration charges on a property purchase. Supports all 28 states + 8 UTs with buyer-gender concessions, urban/rural overrides, and commercial/agricultural multipliers. Pass constructionStatus to also itemize GST (under-construction 1%/5%, ready/resale 0%) for an all-in statutory quote. Returns supported=false for states outside India (supported set named in rateBasis). Not legal/tax advice. Always surface the disclaimer.

}🟢get_property_details(listingId)
Fetch full public details for one AVnester listing by its listingId. Get the listingId from search_properties results first (the `listingId` field) — IDs are not guessable, so this tool is the natural follow-up to a search. AVnester's catalog covers Coimbatore and Chennai; unknown or unpublished IDs return { listing: null, notFound: true } (never throws, to avoid leaking existence). Use when the user references a specific listing. Read-only, no side effects.

}🟢compare_properties(listingIds)
Compare 2–5 AVnester listings by listingId, side-by-side. Get IDs from search_properties first (not guessable). If the user has more than 5 candidates ("compare all"), pick the most relevant 5 (cheapest / largest / best price-per-sqft) and say so. Returns each listing plus pricePerSqft, vsCheapestPercent (0 = cheapest), vsLargestAreaPercent (0 = largest). Covers Coimbatore and Chennai; unknown IDs return not_found_or_unpublished. Does NOT recommend a purchase. Always surface the disclaimer.

}🟢get_property_decision_intelligence(listingId, propertyValue, state, city, firstSale, ...)
Assess whether a buyer can afford a specific Indian home — ONE verdict (AFFORDABLE / STRETCH / NOT_YET / INELIGIBLE) combining indicative eligibility (FOIR/LTV/CIBIL), EMI, true cash-to-close (down payment + stamp duty + registration + itemized GST), regime-aware tax, and an indicative lender-fit triage.
