12 AI prompts to verify Indian home cost decisions — copy & paste templates

Free, expert-curated prompts for ChatGPT, Claude, and Gemini. Each casts the right Indian expert (structural engineer, banking advisor, property lawyer, modular kitchen designer, etc.) and asks 3-4 specific cross-check questions that catch common mistakes our calculators see every week.

Why structured AI prompts beat asking generic questions

Asking ChatGPT "is my contractor quote fair?" produces a generic answer. The same AI, given (a) your specific BOQ inputs, (b) the calculator's quote-check verdict, (c) the right expert role for the question, and (d) 3-4 specific cross-check questions, produces materially better answers. We've encoded that structure for each Indian home cost decision below.

The 12 prompts on this page sit behind the "Verify with AI" button on each Ghar Ka Budget calculator. They auto-fill with your inputs and result. This page exists for two reasons: SEO transparency (people search for "AI prompt for Indian construction cost") and the fact that you can copy any of them and use them in any AI chatbot, with or without our calculator.

Each card includes the AI persona, what the prompt is designed to catch, the full template (click to expand), and a link to the matching calculator.

01

Construction Cost (per sqft) Verifier

AI persona: a structural engineer with deep knowledge of Indian residential construction in 2026
What this catches. Catches: missing line items in your contractor's BOQ (typically waterproofing, electrical, GST), realism check on the per-sqft rate against your seismic zone, and city-specific cost factors a generic per-sqft number can't capture.

EMI vs Rent Decision Verifier

AI persona: an Indian financial advisor specialising in home buying decisions in 2026

2. The calculator does not include home loan tax benefits (Section 24 interest, Section 80C principal, Section 80EE/EEA where applicable). How much do these typically tilt the verdict toward buying for someone in my income bracket?
3. What 3 non-financial factors (lifestyle stability, neighbourhood quality, family circumstances, job mobility) should weigh on this decision but are not in the model?
4. Given the verdict and my inputs, what 2-3 questions should I sit with for a week before committing either way?

05

Prepay vs SIP Decision Verifier

AI persona: an Indian personal finance advisor specialising in home loans, tax planning and equity SIP decisions in 2026
What this catches. Catches: whether the verdict correctly handled your tax regime (new vs old, self-occupied vs let-out, Section 24 ₹2L cap), realism on whether you would actually maintain SIP discipline through a market drawdown, and whether a hybrid (part-prepay + part-SIP) makes more sense than going all-in on either path for your life stage.

MY INPUTS:
{INPUTS}

CALCULATED VERDICT:
{RESULT}

Acting as {ROLE}, please:
1. Is the verdict appropriate given my tax setup? Specifically, did the calculator handle the new tax regime (no Section 24 deduction on self-occupied home) vs old regime (₹2L cap) vs let-out (uncapped) correctly for someone in my situation?
2. The model assumes I would actually invest the monthly surplus consistently in SIP. Realistically, what fraction of Indian households maintain SIP discipline through a 2-3 year market drawdown? How should that change my decision?
3. Beyond the corpus comparison, what 2-3 liquidity, behavioural, or life-stage factors should weigh on this decision but aren't in the math? (e.g. emergency fund readiness, job stability, debt-aversion comfort)
4. Should I split the surplus — say 50% prepay + 50% SIP — instead of going all-in on either path? When does a hybrid actually make sense vs being a hedge against not deciding?

06

Home Loan Balance Transfer Decision Verifier

AI persona: an Indian personal finance advisor specialising in home loans and refinancing decisions in 2026
What this catches. Catches: whether the new rate offer is actually competitive against May 2026 market (best 7.10–7.50%, typical 7.75–8.75%), the rate-reset negotiation move you should make with your current lender before transferring, hidden costs (property re-insurance, top-up bundling pressure, prepayment lock-ins on the new loan), and the 30–45 day transition window operational steps to avoid a missed-EMI CIBIL hit.

I used Ghar Ka Budget's Home Loan Balance Transfer calculator to decide whether to refinance my home loan to a lower-rate lender.

MY INPUTS:
{INPUTS}

CALCULATED VERDICT:
{RESULT}

Acting as {ROLE}, please:
1. Given the post-December-2025 repo cut (5.25%) and current Indian home loan rate spread (best 7.10-7.50%, typical 7.75-8.75%), is the new rate I've been offered actually competitive for my profile, or is there room to push for 25-50 bps lower? What lenders are most aggressive in May 2026 for a borrower like me?
2. Before transferring, what specific negotiation move should I make with my current lender first? Walk me through the exact ask, the conversion fee I should expect, and the rate reduction I can realistically obtain without leaving my bank.
3. The calculator includes processing fee, foreclosure (zero for floating per RBI), valuation, legal, CERSAI, and fresh stamp duty. What other hidden costs in Indian balance transfers do borrowers commonly miss? (e.g. property re-insurance with new lender, top-up bundling pressure, prepayment lock-in clauses on the new loan)
4. The 30-45 day transition is the highest-risk window for a CIBIL hit. What 3 specific operational steps should I take during that period to ensure neither bank reports a missed payment, and what's my fallback if the new lender's disbursement is delayed beyond my next EMI date?

PMAY 2.0 Eligibility & Subsidy Verifier

AI persona: an Indian banking advisor and PMAY-U 2.0 scheme expert familiar with all six eligibility filters and PLI claim procedures in 2026
What this catches. Catches: whether female-ownership timing is fixable post-sanction in your case (EWS/LIG only), realistic property type and locality you'll find under the ₹35L cap in your specific tier-1 city, the 30-day PLI claim filing risk and how to enforce it, and other state-level / women-specific housing schemes that stack with PMAY but commonly go untapped.

MY INPUTS:
{INPUTS}

ELIGIBILITY VERDICT AND SUBSIDY ESTIMATE:
{RESULT}

Acting as {ROLE}, please:
1. Did the calculator correctly handle my income category (EWS/LIG/MIG) and the corresponding female-ownership requirement? Specifically: if I'm in LIG (Rs 3-6L income) but the property is only in my name (male), can my spouse be added to the title after disbursement to retain PMAY eligibility, or is the registration window before sanction?
2. The Rs 35L property cap and Rs 25L loan cap are the most common disqualifiers I'm reading about. In tier-1 cities like Mumbai, Bangalore, Delhi NCR and Pune, are there any builder-affiliated PMAY-approved projects below this cap that I should know about? What's the realistic property type and locality I'd actually find under Rs 35L in those markets in 2026?
3. PLIs (banks/HFCs) are required to file the subsidy claim within 30 days of disbursement, but many miss this. What 3 specific operational steps should I take during loan processing to ensure my PLI actually files the claim on time, and what's my recourse if they miss the deadline?
4. Beyond PMAY 2.0 ISS, what other government schemes (state housing boards, MIG-segment subsidies in specific states, women-only schemes, Stamp Duty concessions) should I check that often go untapped for buyers in my profile? Some states have parallel benefits that stack with PMAY.

LTCG on Property Sale Tax Verifier

AI persona: an Indian Chartered Accountant specialising in capital gains tax planning for property sales under the Budget 2024 dual-regime in 2026
What this catches. Catches: which date counts as "acquisition" for the 23-July-2024 dual-regime cutoff if you bought via builder allotment letter or under-construction property, edge cases with multiple improvements / inheritance / co-owners, the right order to think about exemption planning (CGAS parking vs immediate house purchase vs 54EC bonds), and the surcharge layer on top of the 12.5%/20% + 4% cess that the calc deliberately omits.

I used Ghar Ka Budget's LTCG on Property Sale calculator to estimate tax on my property sale under the Budget 2024 dual-regime.

MY INPUTS:
{INPUTS}

CALCULATED RESULT:
{RESULT}

Acting as {ROLE}, please:
1. Did the calculator correctly identify whether my property qualifies for the dual-regime choice (acquired before 23 July 2024)? If I bought via builder allotment letter / under-construction property, what's the relevant acquisition date for the cutoff - the date of the allotment letter, possession, or registered sale deed?
2. The calc picked Method A (12.5% no indexation) or Method B (20% with indexation). Are there cases where this comparison gets more complex - e.g. property bought partially through inheritance, multiple improvements over the years, or co-owner with different acquisition dates? What should I sanity-check?
3. For exemption planning - if I haven't yet decided whether to invest in a new house (Sec 54/54F) or 54EC bonds, what's the order I should think about it? Is parking in Capital Gains Account Scheme (CGAS) before ITR due date a good interim move, and which nationalised banks actually offer it smoothly in 2026?
4. Surcharge layer: my LTCG plus salary may push my total income past Rs 50L / Rs 1Cr. The calc shows tax + 4% cess but not surcharge. What surcharge percentage applies in my income band, and is the 15% cap on LTCG surcharge per Budget 2022 still in force for May 2026?

Be specific to Indian Income Tax Act 1961 provisions (Sec 45, 48, 54, 54F, 54EC) and current 2026 ITR filing practice. Concise.

Rental Yield & Investment Return Verifier

AI persona: an Indian property investment analyst familiar with rental economics across tier-1, tier-2 and tier-3 cities in 2026
What this catches. Catches: whether your assumed rent is achievable in the specific locality, what local factors (metro/IT/oversupply) should sway your capital-appreciation assumption, restructuring options to improve poor yields (co-living, short-stay, commercial conversion, student housing), and the exit framework around 24-month LTCG threshold + Sec 54 rollover.

I used Ghar Ka Budget's Rental Yield calculator to evaluate a rental property investment.

MY INPUTS:
{INPUTS}

CALCULATED RESULT:
{RESULT}

Acting as {ROLE}, please:
1. The calculator showed my gross/net/after-tax yields and a 10-year benchmark vs FD/Debt MF/Equity MF. For my specific city and locality (mentioned in inputs), is the rent I'm assuming actually achievable, or is there a market gap (e.g. builder marketing rents higher than what tenants actually pay, or society maintenance creeping above my estimate)? What 3 real-world rent-suppressing factors should I budget for that the calculator might miss?
2. The capital appreciation assumption is the single biggest swing factor in the 10-year return. For my city/locality in 2026, what's a realistic appreciation range, and what specific local factors (infrastructure projects, new metro lines, IT corridor demand, oversupply of new launches) should make me bullish or bearish on this assumption?
3. If the rental yield is poor (1-2% after-tax), is there a way to restructure the deal to improve economics? Options: (a) co-living / shared accommodation (3-4 tenants instead of family), (b) Airbnb / short-stay rentals, (c) commercial conversion if zoning permits, (d) student housing near colleges. What works in my locality?
4. For exit planning: if this property doesn't work out, when should I sell? Should I plan around the 24-month LTCG threshold, time it with a market peak, or use Sec 54/54F to roll into a better property without tax leakage? What's the right exit framework given the math you saw?

What this catches. Catches: TDR-zone / coastal / airport-funnel / heritage-precinct factors that swing real margins ±10% from the calc, the prioritised list of negotiation asks based on margin band, immediate pre-DA next steps (RERA verification, bank guarantee structure, jurisdiction clause), and the 3 most common Mumbai redev failure modes + protective clauses.

MY INPUTS:
{INPUTS}

CALCULATED RESULT:
{RESULT}

Acting as {ROLE}, please:
1. The calculator's margin estimate is rough (deliberately so - real DCPR 2034 redev involves TDR loading, road-widening setbacks, height restrictions in heritage/CRZ/airport-funnel zones, and IOD/OC cycle delays that swing real margins +/- 10%). For my specific plot location (mentioned in inputs) in Mumbai, what local factors should I sanity-check that could materially change this number? Specifically: am I in a TDR-receiving zone, a coastal-regulation zone, near a DP Road earmarked for widening, or in an airport-funnel/heritage precinct?
2. The developer is offering a specific carpet + corpus + rent package. Based on my margin calculation, is this proposal under-paying, fairly priced, or generous? What are 3-5 specific negotiation asks I should table at the next society meeting, prioritized by what's most achievable given the margin?
3. We have 75% member majority resolution at our society. What are the immediate next steps before signing the Development Agreement - structural audit by which licensed engineer, RERA registration verification of the developer (track record on past redev projects), bank guarantee structure (which scheduled bank, what percentage of rehab cost), penalty clauses for delay, and Bombay High Court vs arbitration jurisdiction clause?
4. What are the 3 most common ways Mumbai redev projects fail or get stuck mid-execution (developer bankruptcy, FSI dispute with BMC, member faction blocking IOD, contractor walking off site), and what protective clauses in the DA prevent each one?

Frequently asked questions

What is the "Verify with AI" feature on Ghar Ka Budget?
Every calculator at Ghar Ka Budget has a "Verify with AI" button on the result panel. Clicking it opens a curated prompt — pre-filled with your inputs, the calculated result, and a recommended Indian-context expert role — that you can paste into ChatGPT, Claude, or Gemini for a second opinion. The goal is not to replace the calculator with AI, but to give you a structured way to stress-test our number with a different framing.
Why use a structured prompt instead of just asking ChatGPT directly?
Generic AI questions like "is my contractor quote fair?" produce generic answers. A structured prompt that includes (a) your specific inputs, (b) the calculator's computed result, (c) the right expert role for the question (structural engineer for construction, banking advisor for EMI, property lawyer for stamp duty), and (d) 3-4 specific cross-check questions produces materially better answers. These templates encode that structure for each Indian home cost decision.
Are these prompts free to use? Can I copy them?
Yes — every prompt on this page is free to use. Copy any prompt and use it with any AI chatbot. Replace the placeholders ({INPUTS}, {RESULT}, {ROLE}) with your specific situation. We publish them openly because we believe the home-buying decision is too important to gate behind paywalls or vendor lock-in.
Which AI tool works best for these prompts in 2026?
For Indian construction, real estate, and home loan questions, all three major chatbots (ChatGPT, Claude, Gemini) handle these prompts adequately. ChatGPT 4-class and Claude 3.5+ tend to be most specific about Indian context (state-wise stamp duty, city-wise rate ranges, RBI rate norms). Gemini handles them too. The prompt structure matters more than the specific tool — our templates are tool-agnostic.
Does Ghar Ka Budget use AI to generate its calculator results?
No. Every Ghar Ka Budget calculator is a deterministic Indian-context formula running locally in your browser — based on CPWD SOR rates, MOSPI WPI, state stamp duty notifications, and primary government source data. AI is offered only as a verification layer for users who want a second opinion on the calculator's result. The calculator math is auditable in the page source and documented at our methodology page.
