Introduction
Buying a home is the largest financial commitment most people make in their lifetime. In India, there's immense pressure to buy—from parents, society, and the belief that "rent is wasted money." But financially, buying only makes sense under specific conditions. This guide cuts through the emotion and societal pressure to help you understand exactly when buying a home is a smart financial decision—and when it isn't.
Key Takeaways
- 5 critical conditions: 10+ year stay, 30-35% down, EMI <35% income, rent-to-price >0.35%, emergency fund + other investments
- Don't buy because: Society pressure, 'rent is waste,' tax savings alone—you can lose ₹29L saving ₹1L tax
- Financial breakeven: Typically 7-10 years due to 13-18% transaction costs in India
- Tier matters: Tier 2/3 favors buying, Tier 1 favors renting in most cases
- Run the checklist: 8/8 = buy. Below 4/8 = build corpus first.
The 5 Critical Conditions for Buying to Make Sense
Buying a home makes financial sense when ALL of these conditions are met:
1. You Plan to Stay 10+ Years
Why it matters: Real estate transaction costs in India are brutal. Stamp duty: 5-7% of property value. Registration: 1-2%. GST (under-construction): 5%. Brokerage (if applicable): 1-2%. Legal fees, processing: 1-2%. Total: 13-18% of property value. Example: ₹50 lakh property → ₹6.5-9 lakh in transaction costs. To recover these costs through appreciation, you need TIME. At 5% annual appreciation: Year 1: ₹2.5L gain, still ₹4-6.5L below breakeven. Year 3: ₹7.9L gain, roughly at breakeven. Year 5: ₹13.8L gain, finally ahead. Year 10: ₹31.4L gain, clearly profitable. Rule: Don't buy unless you're 80% sure you'll stay 10+ years.
2. You Can Afford 30-35% Down Payment
Why it matters: If you can only afford 10-15% down payment, you're taking on too much debt. The Math: Property ₹50 lakhs, Down payment + costs 30% = ₹15 lakhs, Loan ₹35 lakhs, EMI ₹28,000 at 8.5% for 20 years. vs if you borrow 90%: Down payment 10% = ₹5 lakhs (plus ₹6.5L costs from savings), Loan ₹45 lakhs, EMI ₹36,000 at 8.5% for 20 years. Impact: ₹8,000 higher EMI (28% more), ₹19.2 lakhs more interest over 20 years, Higher financial stress. Safe Rule: Down payment + transaction costs should be ≤ 50% of your total savings. Never deplete all savings for a house.
3. EMI is Less Than 40% of In-Hand Salary
Why it matters: High EMI-to-income ratio = financial stress and no room for emergencies. Example 1 Safe: In-hand salary ₹80,000/month, EMI ₹28,000 (35%), Remaining ₹52,000 for expenses, savings—Manageable. Example 2 Risky: In-hand ₹60,000/month, EMI ₹32,000 (53%), Remaining ₹28,000—One emergency destroys you. Conservative Rule: EMI should be maximum 35% of in-hand salary (not gross salary). Optimal Rule: Keep it under 30% to maintain quality of life.
4. Rent-to-Price Ratio Works in Your Favor
What is Rent-to-Price Ratio: (Monthly Rent ÷ Property Price) × 100. Example: Property ₹50 lakhs, Equivalent rent ₹15,000/month, Ratio = (15,000 ÷ 50,00,000) × 100 = 0.3%. Decision Framework: Ratio > 0.5%: Buying makes strong financial sense (common in Tier 2/3). Ratio 0.35-0.5%: Borderline, depends on other factors. Ratio < 0.35%: Renting is financially smarter (common in Mumbai, Bangalore, Pune). City-wise: Mumbai 0.15-0.25%, Bangalore 0.25-0.3%, Pune 0.25-0.35%, Hyderabad/Chennai 0.3-0.4%, Tier 2: 0.4-0.6%.
5. You Have Emergency Fund + Other Investments
Why it matters: Don't put all eggs in one illiquid basket. Before buying, you should have: Emergency Fund: 6-12 months expenses in liquid funds. If monthly expense is ₹50,000, emergency fund: ₹3-6 lakhs minimum. Existing Investments: 50-100% of property value in other assets. Buying ₹50 lakh house? Should have ₹25-50 lakh in mutual funds, PPF, stocks, etc. Why: Medical emergency during home loan? You need liquid funds. Job loss? EMI continues, you need backup. Better opportunity? Locked capital prevents you from seizing it. Red Flag: If buying a house wipes out all your savings and investments, DON'T BUY YET.
Rent-to-Price Ratio
- Formula: (Monthly Rent ÷ Property Price) × 100
- >0.5%: Buying strong. Example: ₹30L property, ₹15K rent. Tier 2/3 cities.
- 0.35-0.5%: Borderline. Consider job stability, tax benefits.
- <0.35%: Renting smarter. Example: ₹80L, ₹20K rent = 0.25%. Mumbai, Bangalore, Pune.
- City-wise: Mumbai 0.15-0.25% (rent). Bangalore 0.25-0.3% (rent). Pune 0.25-0.35% (borderline). Hyderabad/Chennai 0.3-0.4% (mixed). Tier 2: 0.4-0.6% (buy).
Additional Factors That Strengthen Buying
- Stable career: Government, doctors, lawyers, tenured professors, PSU, senior (10+ yrs). Risky: IT, consultants, startup, fresh grads, gig workers.
- Sweet spot age 30s-40s: Career stable, family, 20-25 yr loan paid by retirement. 20s = build liquid first. 50s+ = shorter tenure, may want liquidity.
- Tax benefits (old regime): ₹2L interest + ₹1.5L 80C = ₹3.5L deduction. Tax saved ₹1.05L/yr at 30% = ₹21L over 20 yrs. Effective rate ~6.3%. New regime: no benefit except 80EEA ₹1.5L first-time.
- Below-market deals: Family property, distress sale (15-20% off), pre-launch (10-15% off, risky), auction (20-30% off, complex), employer subsidy.
- High appreciation potential: Metro/ infra, IT parks, govt projects, underdeveloped prime location. Don't trust builder promises—check RERA.
When Buying Does NOT Make Sense
- Relocating for 2-3 yr project: Projects change. Rent, save, buy when career stabilizes.
- Entire net worth in one property: ₹20L savings, ₹50L property, after down = broke + ₹35L debt. Build ₹40-50L corpus first.
- Buying to 'save tax': Save ₹1L tax, pay ₹30L interest = net LOSE ₹29L. Tax tail shouldn't wag the dog.
- 'Rent is waste' myth: Invest down + (EMI-rent) @ 12% = ₹2.94 cr vs property ₹1.33 cr. 2.2x more wealth by renting!
- Under-construction with uncertain timeline: Builder delays common. Buy ready-to-move when possible.

Quick Decision Checklist
- Plan to stay 10+ years (80% confident)
- 30-35% down + costs (without depleting savings)
- EMI <35% of in-hand salary
- 6-12 months emergency fund separate from down payment

- Job stable (5+ years confidence)
- Emotionally ready for 20-year commitment
- Score: 8/8 = buy. 6-7 = good. 4-5 = wait 1-2 yrs. <4 = build corpus first.
How to Make Buying Work Better
- Negotiate: Price 5-10% off, compare 5+ banks for 0.25-0.5% lower rate, waive processing. ₹50L property: ₹5.5L+ savings possible.
- Tenure: Take 20-yr but prepay whenever possible. Year 1-5 prepay has max impact.
- Prepay: Bonus, 1-2 extra EMIs/yr. ₹35L loan + ₹1L/yr prepay = clears in 14 yrs, save ₹12-15L interest.
- Tax: Old regime—use full ₹2L interest, ₹1.5L 80C. New—80EEA if first-time.
- Rent spare room: ₹8-10K reduces effective EMI. Let-out portion interest deductible.
The Hybrid Approach
If buying in your city doesn't make sense: Rent in Tier 1 (Bangalore ₹25K), buy in Tier 2 (Indore ₹35L). Take ₹28L loan, EMI ₹22.4K, rent out ₹12K. Net ₹35.4K. Benefits: Own property, build equity, rental income, tax benefits, freedom to relocate.
Real Example: Ankit, 34, Civil Engineer, Hyderabad
📊 2020: Government job, ₹15 LPA, ₹30L savings, rent ₹18K, found ₹50L property
Final Thoughts
Buying can be great—or terrible. Difference: TIMING and CIRCUMSTANCES. Buy when conditions right, numbers work, emotionally ready. Don't when career unstable, can't afford 30% down, EMI >35%, terrible rent-to-price, would deplete savings. Your home is where you live, not necessarily your best investment. Building wealth matters more than owning property. Make YOUR decision—run numbers, check boxes, decide with head not heart.
