Case Studies

Six detailed real estate investment scenarios with real numbers. Each case study guides you step by step through the analysis, from financial structuring to net results, using our simulators.

Tax data last updated : April 2026

Scenario

  • Purchase of a 45 sqm two-bedroom apartment in Lyon (residential area) for EUR 180,000.
  • Notary fees: EUR 14,400 (8%). Light renovation: EUR 10,000 (paint, flooring, kitchen).
  • Total project cost: EUR 204,400.
  • Expected rent: EUR 750/month (unfurnished).

Financing

  • Down payment: EUR 20,000 (notary fees + part of renovation).
  • Loan: EUR 184,400 at 3.5% over 25 years.
  • Monthly payment: EUR 921/month (including insurance).

Steps in the simulator

  1. Enter the purchase price (EUR 180,000), notary fees (EUR 14,400) and renovation (EUR 10,000).
  2. Configure the loan: amount EUR 184,400, rate 3.5%, duration 25 years.
  3. Enter the monthly rent (EUR 750) and charges: property tax EUR 900/year, condo fees EUR 1,200/year, PNO insurance EUR 200/year, vacancy rate 5%.
  4. Compare tax regimes in the results tab.

Key results

Annual gross rentEUR 9,000
Total project costEUR 204,400
Gross yield4.4%
Annual chargesEUR 2,300 (tax + condo + insurance)
Vacancy (5%)EUR 450/year
Net yield3.1%
Monthly cash flow (rent - mortgage)EUR -170
Annual savings effortEUR 2,040

Unfurnished vs LMNP (furnished real regime)

By switching to furnished rental (LMNP real regime), rent can increase to EUR 850/month thanks to the furniture premium (+13%). More importantly, the real regime allows deducting depreciation on the property (approx. EUR 5,500/year) and furniture (approx. EUR 1,500/year), totaling EUR 7,000 in additional deductions.

Result: taxable income drops to zero for several years, and monthly cash flow goes from EUR -170 to EUR -70/month (850 - 921). Net-net yield jumps significantly thanks to near-zero taxation.

Monthly rentEUR 750 -> EUR 850
Deductible depreciationEUR 0 -> EUR 7,000/year
Taxable incomeEUR 6,250 -> EUR 0
Monthly cash flowEUR -170 -> EUR -70
Net-net yield1.8% -> 3.2%

Key takeaway

The tax regime can transform a mediocre investment into a good deal. LMNP real regime is often the game-changer that tips a project into positive territory. Before dismissing a property, always test different tax regimes in the simulator.

Simulate a rental investment

Scenario

  • Purchase of a 5-unit building in Limoges for EUR 250,000.
  • Notary fees: EUR 20,000 (8%). Major renovation: EUR 80,000 (roof, facades, electrical upgrade, unit refresh).
  • Total cost: EUR 350,000.
  • Mix: 2x 2-bed at EUR 450/month, 2x 3-bed at EUR 550/month, 1x studio at EUR 350/month.
  • Total monthly rent: EUR 2,350/month, i.e. EUR 28,200/year.

Financing

  • Down payment: EUR 35,000 (10% of total cost).
  • Loan: EUR 315,000 at 3.8% over 20 years.
  • Monthly payment: EUR 1,890/month (including insurance).

Key results

Annual gross rentEUR 28,200
Total project costEUR 350,000
Gross yield8.1%
Annual chargesEUR 5,600 (tax EUR 2,800 + insurance EUR 400 + maintenance EUR 2,400)
Vacancy (7%)EUR 1,974/year
Net yield5.9%
Monthly cash flow (rent - mortgage)EUR +460 before charges
Cash flow after chargesApproximately neutral (charges ~EUR 467/month)

Vacancy risk diversification

With 5 units, losing one tenant represents a 15-21% income loss (depending on the unit), versus 100% with a single property. Even with one vacant unit, income from other units covers most of the charges.

An apartment building also allows cost pooling for renovation: replacing the roof benefits all units. The maintenance budget should be set at 15% of rent to anticipate recurring work.

1 vacant unit (studio)Loss: 15% of income. Cash flow: EUR -230/month
1 vacant unit (3-bed)Loss: 23% of income. Cash flow: EUR -430/month
Single property vacantLoss: 100% of income

Detailed analysis

Key strategies: Renovate to a good standard to attract quality tenants and reduce turnover. Diversify unit types (studio, 2-bed, 3-bed) to reach different tenant profiles. Budget 15% of rent for maintenance and repairs.

Under LMNP real regime, depreciation on the property (approx. EUR 9,300/year) and renovation costs (depreciated over 10-15 years) make the operation virtually tax-neutral for the first 10 years.

Key takeaway

Volume + renovation = higher yields + diluted risk. An apartment building in a mid-size city offers the best return-to-risk ratio for investors willing to manage multiple units. Tenant diversification is your best protection against vacancy.

Simulate an apartment building

Scenario

  • Purchase of a 60 sqm apartment in Bordeaux for EUR 120,000 (property in very poor condition, below market price).
  • Notary fees: EUR 9,600 (8%).
  • Full renovation: EUR 45,000 (kitchen, bathroom, floors, electrical, paint). Renovation duration: 4 months.
  • Total operation duration: 6 months (renovation + listing + sale period).
  • Estimated resale price: EUR 210,000 (market price for a renovated unit).

Financing

  • Down payment: EUR 30,000.
  • Loan: EUR 144,600 (purchase + notary + renovation) at 4% over 15 years.
  • Interest over 6 months: approximately EUR 2,100.

Key results

Resale priceEUR 210,000
Purchase price-EUR 120,000
Notary fees-EUR 9,600
Renovation-EUR 45,000
Holding costs (6 months)-EUR 3,600 (interest 2,100 + insurance 300 + charges 1,200)
Agent commission (6%)-EUR 12,600
Gross marginEUR 19,200
Taxable capital gainEUR 19,200 (no allowance before 6 years)
Tax (IR 19% + social 17.2% = 36.2%)-EUR 6,950
Net profitEUR 12,250
ROI on down payment (EUR 30,000)40.8% in 6 months
Annualized ROI~81.6%

Detailed analysis

Fix & flip is one of the most profitable real estate operations, but also one of the riskiest. Success rests on three pillars: buying below market (15-25% discount), controlling the renovation budget (allow 10-15% contingency), and selling quickly (each extra month erodes the margin).

Main risks: renovation budget overrun (structural surprises), declining market during the operation, longer sales period than expected (increases holding costs). A failed flip can turn an expected EUR 12,000 gain into a EUR 5,000 loss.

Key takeaway

Flipping can generate exceptional returns over short periods, but it requires accurate renovation cost estimation, good local market knowledge, and rapid execution. This is not passive investing: it is an entrepreneurial project.

Simulate a fix & flip

Scenario

  • Investor in the 41% tax bracket, already owns a 3-bed in Paris rented unfurnished at EUR 1,200/month (EUR 14,400/year).
  • Buys an energy-inefficient studio (DPE F rating) in Nantes for EUR 80,000.
  • Plans EUR 50,000 in energy renovation to reach DPE C (insulation, windows, heating).
  • The studio will be rented at EUR 500/month from the second half of the year (EUR 6,000/year at full occupancy).

Financing

  • Down payment: EUR 20,000 for the studio.
  • Loan: EUR 110,000 (studio + renovation) at 3.5% over 20 years.

Key results

Year 1 rental incomeEUR 14,400 (Paris) + EUR 3,000 (Nantes, 6 months) = EUR 17,400
Year 1 renovation (1st tranche)EUR 35,000
Deductible chargesEUR 4,000 (interest + insurance + management)
Rental resultEUR 17,400 - 35,000 - 4,000 = EUR -21,600
Offset against global incomeEUR 21,400 max (energy sieve DPE F)
Deficit applied year 1EUR 21,400
Tax savings year 1EUR 21,400 x 41% = EUR 8,774
Carry-forward deficitEUR 200 (21,600 - 21,400) carried to rental income

Tax impact over 2 years

Year 2: Remaining works EUR 15,000. Income EUR 20,400 (Paris + Nantes full year). Charges EUR 4,000. Result: 20,400 - 15,000 - 4,000 - 200 (carry-forward) = EUR 1,200 taxable. Tax: 1,200 x 58.2% (41% TMI + 17.2% social) = EUR 698.

Without rental deficit: EUR 20,400 x 58.2% = EUR 11,873 annual tax. Over 2 years, total savings exceed EUR 20,000.

Year 1 savingsEUR 8,774
Year 2 savingsEUR 11,175 (11,873 - 698)
Total savings over 2 years~EUR 19,949
Studio value increase (DPE F -> C)+15 to 20%, i.e. +EUR 12,000 to 16,000

Key takeaway

Rental deficit is the most powerful tax weapon for high-bracket investors (30%, 41%, 45%). By combining energy renovation with rental deficit, you massively reduce your taxes while upgrading your assets. Since 2023, the ceiling is raised to EUR 21,400/year for energy sieves.

Simulate a rental deficit

Scenario

  • Couple (30% tax bracket each) owning 3 rental properties, total value EUR 600,000.
  • Gross rental income: EUR 36,000/year. Loan interest: EUR 8,000/year. Charges: EUR 6,000/year.
  • Currently held personally under real regime: rental income taxed at 30% TMI + 17.2% social contributions = 47.2%.
  • Taxable income under personal ownership (real regime): 36,000 - 8,000 - 6,000 = EUR 22,000. Tax: 22,000 x 47.2% = EUR 10,384.

Financing

  • SCI creation: approximately EUR 1,500 (articles of association + formalities).
  • Property transfer costs: approximately 7% of value, i.e. EUR 42,000 (transfer duties). This cost is the main barrier to the operation.

Key results

Rental incomeEUR 36,000/year
Depreciation (80% x 600,000 / 30 years)-EUR 16,000/year
Loan interest-EUR 8,000/year
Deductible charges-EUR 6,000/year
SCI taxable resultEUR 6,000
Corporate tax (reduced rate 15%)EUR 900
SCI net resultEUR 5,100
Dividend distribution (PFU 31.4% — LFSS 2026)EUR 5,100 x 31.4% = EUR 1,601
Net received by coupleEUR 3,499
Total taxation (IS + PFU)EUR 2,501
Taxation under personal ownership (real regime)EUR 10,384
Annual savingsEUR 7,883

Beware the exit trap

The SCI under corporate tax has a major trap at resale: capital gains are calculated on the net book value (after depreciation), not the original purchase price. If you sell after 20 years of depreciation, the capital gains tax base is considerably increased.

Example: property purchased for EUR 200,000, cumulative depreciation of EUR 106,667. Book value: EUR 93,333. Resale at EUR 250,000. Corporate capital gain: EUR 250,000 - 93,333 = EUR 156,667, taxed at 25% = EUR 39,167. Under personal ownership, after 20 years of allowances, the capital gain would have been virtually tax-exempt.

Annual IS savings (over 20 years)~EUR 157,660 cumulative
Extra capital gains tax at exit~EUR 39,167 per property (estimate)
Net gain after exitPositive for long-term holds

Key takeaway

SCI under corporate tax drastically reduces annual taxation through depreciation, but creates a major tax cost at resale. It is the ideal strategy for assets intended for long-term holding or estate transfer (share donation with 10-15% discount). The primary advantage of IS is the ability to deduct depreciation (EUR 16,000/year), which is not possible under personal ownership.

Simulate a real estate holding

Scenario

  • An investor (30% tax bracket) has EUR 100,000 to invest in real estate.
  • Option A: Buy diversified SCPI shares.
  • Option B: Buy a studio apartment directly with a bank loan.
  • Investment horizon: 10 years.

Key results

SCPI: Amount investedEUR 100,000
SCPI: Entry fees (9%)-EUR 9,000 (withdrawal value: EUR 91,000)
SCPI: Annual distribution (4.5%)EUR 4,500 gross/year
SCPI: After tax (TMI 30% + social 17.2% = 47.2%)EUR 2,376 net/year
SCPI: Cumulative net over 10 yearsEUR 23,760
Direct: Down paymentEUR 30,000
Direct: LoanEUR 70,000 at 3.5% over 20 years (payment: EUR 406)
Direct: RentEUR 500/month = EUR 6,000/year
Direct: Annual charges + taxes~EUR 2,100
Direct: Monthly cash flowEUR -50/month (savings effort)
Direct: Cumulative effort over 10 years-EUR 6,000

Balance sheet at 10 years

SCPI: Capital invested EUR 100,000 + cumulative net distributions EUR 23,760. Stable withdrawal value at EUR 91,000 (conservative assumption). Total wealth: ~EUR 114,760. Zero management, zero stress, diversification across 100+ properties. Important: SCPI income is taxed as rental income (TMI + 17.2% social contributions), NOT as flat tax.

Direct investment: Property purchased EUR 100,000, valued at ~EUR 115,000 (+1.5%/year). Remaining loan balance: ~EUR 45,000. Equity in property: EUR 70,000. Cumulative cash flow: -EUR 6,000. Net wealth: EUR 115,000 - 45,000 - 6,000 = EUR 64,000 net. Plus the EUR 70,000 that was not invested.

SCPI: Wealth at 10 years~EUR 114,760 (91k + 23.8k distributions)
Direct: Wealth at 10 years~EUR 109,000 (115k property - 45k loan + adjustments)
SCPI: Management requiredNone (100% passive)
Direct: Management requiredActive (tenants, repairs, accounting)
SCPI: Leverage effectNone
Direct: Leverage effectx3.3 (100k / 30k down payment)

Detailed analysis

SCPI offers simplicity, diversification, and regular returns with zero management. But without leverage, the return on invested capital remains moderate. Important: SCPI income is taxed as rental income (TMI + 17.2% social contributions), not as flat tax (30%).

Direct investment allows using bank credit as a wealth accelerator. The cash flow effort is offset by equity buildup through loan repayment and potential property appreciation.

For the same starting capital, leveraged direct investment generally creates more wealth long-term, but at the cost of management effort and concentrated risk on a single property.

Key takeaway

SCPI for investors who prioritize simplicity and passivity. Direct investment for those who want to maximize leverage and control. The best strategy is often to combine both: direct for leverage, SCPI for diversification.
