I asked ChatGPT to stress-test a ₹1.5 crore home purchase in Gurugram on a ₹25 LPA salary. AI’s response was eye-opening.
My ChatGPT Prompt
Act as a prudent, conservative homebuyer evaluating whether purchasing this home is a wise decision.
Do NOT use assumed property appreciation rates or stock market return assumptions unless explicitly requested.
Your goal is NOT to tell me whether buying or renting is emotionally satisfying.
Evaluate whether buying this home is prudent based on affordability, cash-flow resilience, family needs, and flexibility.

Then, evaluate the following:
Housing Stress Test
Calculate:
- EMI as % of take-home income
- Total housing cost as % of income
- Remaining monthly surplus after all expenses
- Classify safe, stretch and dangerous
- Emergency Fund Analysis
Determine:
- Required emergency fund if renting
- Required emergency fund if buying
Assume:
- 6 months expenses minimum
- 12 months if sole earner
- 18 months if industry risk is high
Tell me:
- How much emergency fund I should have before buying
- Whether buying would leave me underfunded
Job Loss Survival Test
Ignore extreme doomsday scenarios.
Instead analyze:
- Can I survive 6 months without income?
- Can I survive 12 months without income?
Calculate:
- Months of runway after down payment
- Months of runway after registration costs
- Months of runway after furnishing costs
Final Verdict
Place me in one category:
A. Buy now

C. Continue renting
Explain the decision using only affordability, resilience, lifestyle, and family considerations.
Do not use speculative property appreciation assumptions.
ChatGPT’s Response
I evaluated the home purchase conservatively, as a credit committee would. No property appreciation assumptions were used. No stock market return assumptions were considered. The goal was to judge affordability, resilience, family suitability and flexibility.
Monthly household income totals ₹2.1 lakh. Salary contributes ₹1.6 lakh, and the spouse adds ₹50,000 monthly.
The proposed purchase involves a property valued at ₹1.5 crore. The buyer contributes ₹30 lakh upfront and borrows ₹1.2 crore. The EMI stands at ₹1,00,704, with a monthly maintenance charge of ₹4,000.
The current household spending totals ₹90,000, including rent. Actual lifestyle spending, excluding rent, is roughly ₹45,000 per month.
Additional purchase costs matter. Stamp duty, registration, and setup expenses in Gurgaon may add ₹13–20 lakh. Those costs materially affect liquidity.
The housing stress test showed meaningful pressure.
EMI alone accounts for 48% of the monthly income. The total housing cost is about ₹1.05 lakh per month. That equals roughly 50% of take-home income.
After , maintenance and living costs, around ₹60,000 remains each month. It’s a stretch.
The household remains cash-flow positive. However, salary growth expectations remain modest at 3%. Job stability is only average. The purchase is manageable but not comfortable.
I tested emergency reserves next.
Current liquid assets include ₹10 lakh in fixed deposits and ₹30 lakh in equity. EPF and NPS holdings of ₹10 lakh were excluded.
For six months of rent, expenses amount to roughly ₹5.4 lakh. A healthier buffer is ₹8–10 lakh. Existing reserves already satisfy this. Home ownership changes the equation.
Monthly spending rises to roughly ₹1.5 lakh. Minimum reserves should reach ₹9 lakh. A more comfortable cushion is ₹18–20 lakh.
Given the child’s and average career stability, maintaining liquidity of ₹18–20 lakh after purchase appears prudent. The job-loss test became decisive.
Before purchase, liquid assets total about ₹40 lakh. That supports around 26 months of spending. After purchase, liquidity changes dramatically.
The down payment, registration, and furnishing together may require roughly ₹46 lakh. Since current liquid assets are lower, investment liquidation is likely. The remaining cash could fall close to zero.
At that point, surviving six months without income becomes difficult. Twelve months become unrealistic.
Final verdict
Wait 1–3 years and strengthen finances. The issue is not affordability. The issue is resilience.
Build a larger emergency reserve, set aside a down payment, and reduce effective housing costs before buying.
The recommendation is delay, not rejection.
