Key Takeaways
- Pre-sale planning (90 days early) identified replacement candidates before the 45-day clock started.
- Boot analysis ensured replacement property value ($665K > $420K) and debt ($435K > $165K) exceeded relinquished levels.
- DST identification as a safety valve provided emergency backup under the 3-Property Rule.
- Post-closing cost segregation on the excess basis generated $2,584 in additional Year 1 tax savings.
This lesson walks through a complete 1031 exchange from pre-sale planning through post-closing compliance, including the identification strategy, boot calculation, and cost segregation on the replacement property.
Exchange Setup and Pre-Sale Planning
Investor: Chen and Wei, MFJ. Relinquished property: a triplex purchased 8 years ago for $280,000, current value $420,000, outstanding mortgage $165,000. Accumulated depreciation: $81,455. Adjusted basis: $198,545. Estimated gain: $420,000 − $25,200 (selling costs) − $198,545 = $196,255. Estimated tax if sold without exchange: LTCG ($114,800 × 15% = $17,220) + recapture ($81,455 × 25% = $20,364) + NIIT ($196,255 × 3.8% = $7,458) = $45,042 federal. Pre-sale preparation: engaged a QI ($900 fee), identified target replacement criteria (8-12 unit apartment, $550,000-$700,000, 6%+ cap rate), and began searching 90 days before listing.
Exchange Execution
Day 0: Triplex closes for $420,000. After selling costs ($25,200) and loan payoff ($165,000), the QI receives $229,800 in exchange funds. Boot analysis: to avoid mortgage boot, the replacement property must have debt ≥$165,000. To avoid cash boot, all $229,800 must be reinvested as down payment. Target replacement price: $229,800 (equity) + $420,000+ (new loan) = $650,000+ to ensure full deferral with both value and debt exceeding the relinquished levels. Day 38: Chen identifies three properties: (1) a 10-unit apartment for $680,000 (primary target), (2) an 8-unit apartment for $590,000 (backup), (3) a DST interest for $230,000 (safety valve). Identification letter is signed and delivered to the QI. Day 42: the 10-unit passes inspection. Chen negotiates a purchase price of $665,000 with a $435,000 loan (exceeding the $165,000 relinquished debt) and $230,000 equity (absorbing all exchange funds plus $200 in additional cash). Day 168: replacement property closes. QI transfers $229,800 to the title company. Chen contributes $200 from personal funds to cover the equity difference. Full deferral achieved: no cash boot, no mortgage boot.
Post-Closing Optimization
After closing, Chen implements three optimization steps. (1) Form 8824 preparation: the CPA prepares the like-kind exchange reporting, documenting the $196,255 deferred gain and $81,455 deferred depreciation recapture. (2) Basis calculation: exchange basis ($198,545 carryover) + excess basis ($665,000 − $420,000 = $245,000 in additional value funded by the larger mortgage) = $443,545 total basis on the replacement property. (3) Cost segregation: a study ($8,000 fee) on the excess basis ($245,000) identifies $73,500 in reclassifiable components. With 60% bonus depreciation: $73,500 × 60% = $44,100 in Year 1 bonus depreciation, saving $10,584 at the 24% bracket. Net cost seg benefit after study fee: $2,584 in Year 1 plus ongoing accelerated depreciation. Combined Year 1 benefit: $45,042 in deferred taxes + $2,584 in net cost seg savings = $47,626 in total tax optimization.
Go / No-Go Decision Framework
Go Indicators
- ✓Pre-sale planning (90 days early) identified replacement candidates before the 45-day clock started.
- ✓Boot analysis ensured replacement property value ($665K > $420K) and debt ($435K > $165K) exceeded relinquished levels.
No-Go Indicators
- ✗Not immediately establishing new depreciation schedules for the replacement property after closing: Delayed depreciation setup results in missed deductions in the acquisition year and complications in calculating the carryover and new basis components
- ✗Assuming the replacement property's entire value starts a fresh depreciation schedule: Only the new basis (exchange boot plus additional investment) starts a fresh schedule; the carryover basis continues the relinquished property's remaining depreciation—miscalculation overstates deductions
Scenario: Executing a Multi-Property 1031 Exchange with Cost Segregation
Chen and Wei sell a triplex ($420K) with $196K in gain and $81K in depreciation recapture. Without exchange, they face $45,042 in federal taxes. They target a 10-unit apartment at $665K for full deferral.
The exchange deferred $45,042 in federal taxes. Post-closing cost segregation added $2,584 in net Year 1 tax savings. Chen and Wei upgraded from a triplex to a 10-unit apartment complex with $47,626 in total first-year tax benefit, while maintaining full deferral of all prior gains.

Common Mistakes to Avoid
Not immediately establishing new depreciation schedules for the replacement property after closing
Consequence: Delayed depreciation setup results in missed deductions in the acquisition year and complications in calculating the carryover and new basis components
Correction: Work with the CPA to establish replacement property depreciation schedules immediately after closing, separating carryover basis (continuing the old schedule) from new basis (starting a fresh schedule)
Assuming the replacement property's entire value starts a fresh depreciation schedule
Consequence: Only the new basis (exchange boot plus additional investment) starts a fresh schedule; the carryover basis continues the relinquished property's remaining depreciation—miscalculation overstates deductions
Correction: Separate the replacement property's basis into carryover (continuing the original depreciation schedule) and new basis (beginning a new schedule from the acquisition date)
