Key Takeaways
- Four successive 1031 exchanges grew a $45,000 investment to a $2.1M portfolio while deferring $280,000+ in taxes.
- The compound benefit of deferral added $340,000 in additional portfolio value beyond the deferred taxes themselves.
- Without exchanges, the portfolio would be worth approximately $1,480,000 vs. $2,100,000—a $620,000 difference.
- Step-up in basis at death permanently eliminates all deferred gain and recapture for heirs.
This case study follows an investor who performed four successive 1031 exchanges over 15 years, growing a $150,000 initial investment into a $2.1M portfolio while deferring over $280,000 in cumulative capital gains and depreciation recapture taxes. The case illustrates the compound power of the "swap till you drop" strategy.
The Four-Exchange Chain
Exchange 1 (Year 0-4): Purchased a duplex for $150,000 (30% down = $45,000 cash, $105,000 loan). Sold after 4 years for $210,000. Gain: $60,000. Tax deferred: $14,280 (LTCG + recapture). 1031 exchanged into a fourplex for $320,000. Exchange 2 (Year 4-8): Held the fourplex for 4 years, improving NOI through rent increases and operational improvements. Sold for $440,000. Cumulative gain: $130,000. Cumulative tax deferred: $30,940. 1031 exchanged into an 8-unit apartment for $620,000. Exchange 3 (Year 8-12): Held the 8-unit for 4 years with professional management. Sold for $850,000. Cumulative gain: $210,000. Cumulative tax deferred: $49,980. 1031 exchanged into a 16-unit apartment complex for $1,200,000. Exchange 4 (Year 12-15): Held the 16-unit for 3 years. Current value: $2,100,000. Cumulative unrealized gain: $380,000. Cumulative deferred tax: $90,440. Total depreciation deferred through the chain: approximately $190,000 in recapture.
The Compound Impact of Deferral
If the investor had paid taxes at each sale instead of exchanging, the reinvestment amount would have been reduced at each step. Year 4 reinvestment: $210,000 − $14,280 = $195,720 (instead of $210,000). Year 8 reinvestment: $380,000 − $30,940 = $349,060 (instead of $440,000 equivalent). By Year 15, the taxed portfolio would be worth approximately $1,480,000 versus the $2,100,000 exchanged portfolio—a $620,000 difference. Of that difference, approximately $280,000 represents deferred taxes and $340,000 represents the compound growth on the deferred tax capital. The deferred tax capital—money that would have gone to the IRS—instead worked for the investor at 8-10% annual returns for up to 15 years.
The Endgame: Step-Up in Basis at Death
The investor, now 62, plans to hold the 16-unit complex through retirement. If held until death, the heirs receive a stepped-up basis equal to fair market value at the date of death. All deferred capital gains and depreciation recapture—approximately $570,000 in cumulative deferred gain—are permanently eliminated. The heirs inherit the $2.1M property with a $2.1M basis, owing zero capital gains or recapture tax. They can then begin their own depreciation schedule on the stepped-up basis and either hold for income or sell tax-free (no gain above the stepped-up basis). This is the "swap till you drop" endgame—the most tax-efficient wealth transfer strategy in real estate.

Common Mistakes to Avoid
Planning a 1031 exchange chain without considering the endgame strategy (eventual taxable sale vs. hold until death)
Consequence: Without a clear endgame, the investor may be forced into a taxable sale at an inopportune time, realizing decades of accumulated deferred gain at once
Correction: Plan the endgame from the beginning: hold until death for step-up basis, exchange into a "final" property for retirement income, or plan for the eventual tax liability
Assuming the step-up in basis at death is guaranteed to remain in the tax code
Consequence: Legislative changes could modify or eliminate the step-up provision—building an entire strategy around a single tax provision creates concentration risk
Correction: While the step-up has been in the code since 1921, maintain awareness of proposed changes and have contingency plans; 1031 exchange compounding provides benefits even without the step-up
