Improvement/Construction Exchanges: Advisor Planning Notes and Pitfalls
13 min read · For Advisors · Last updated
Key Takeaways
In an improvement exchange, only improvements completed and transferred to the client by Day 180 count toward exchange value. Advisors must stress-test the timeline against contractor delays, permitting issues, and scope changes, and ensure improvement budgets include realistic contingencies.
What an Improvement Exchange Does
An improvement exchange allows a client to acquire below-market replacement property and improve it to full exchange value, deferring tax on the entire amount. The client buys a property that needs work, completes improvements within the 180-day exchange window, and counts the improvement costs toward the exchange value.
Key rule: Only improvements completed and transferred to the client (placed in service) by the end of Day 180 count. Not started. Not substantially complete. Finished and in the client's hands. The IRS does not extend the deadline for construction delays.
Value Counting: What Counts and What Does Not
| Category | Counts Toward Exchange Value? | Examples |
|---|---|---|
| Capital improvements completed by Day 180 | Yes | Roof replacement, HVAC installation, electrical upgrades, plumbing, flooring, windows, fixtures, tenant buildout |
| Repairs and maintenance | No | Fixing existing elements rather than replacing them |
| Cosmetic changes that do not increase value | No | Paint color changes without renovation |
| Soft costs (permits, professional fees) | Maybe | Only if the contract clearly capitalizes these as part of the improvement |
| Work not completed by Day 180 | No | Becomes boot or post-exchange expense |
| Improvements paid after the exchange closes | No | Separate from the exchange structure |
Exchange Value Calculation
| Line Item | Amount |
|---|---|
| Relinquished property sale price | $2,000,000 |
| Replacement as-is purchase price | $1,700,000 |
| Improvement costs (completed by Day 180) | $350,000 |
| Total exchange value | $2,050,000 |
| Boot position | $0 (fully deferred) |
If only $280,000 of improvements are completed by Day 180, total exchange value drops to $1,980,000, creating a $20,000 boot position with a small taxable gain.
Timeline Mechanics
Delayed Improvement Exchange
| Step | Timing | Activity |
|---|---|---|
| Identify replacement property | By Day 45 | Standard identification rules apply |
| Acquire replacement property | By Day 80 | Close on as-is property |
| Complete improvements | Day 80-180 | Contractors execute scope |
| Construction window | ~100 days | Feasible for smaller projects only |
Reverse Improvement Exchange (Preferred)
| Step | Timing | Activity |
|---|---|---|
| EAT acquires replacement property | Day 1 | Exchange Accommodation Titleholder takes title |
| Construction begins | Day 5 | Contractors start immediately under EAT authority |
| Construction complete | Day 140 | All work finished, inspections passed |
| Relinquished property sale closes | Day 160 | QI coordinates transfer |
| Improved property transfers to client | Day 160 | Exchange closes |
| Construction window | ~135 days | Realistic for complex projects |
The reverse structure is preferable because work begins immediately without waiting for the client's acquisition to close.
Project Plan Requirements
Before the EAT acquires the property, lock down five elements:
1. Detailed Scope of Work
Itemize every improvement with price, timeline, and responsible party:
| Item | Specification | Cost | Duration |
|---|---|---|---|
| Roofing | Complete tear-off, new asphalt shingles | $X | X weeks |
| HVAC | Remove 2 old units, install 2 new 5-ton units | $X | X weeks |
| Flooring | Remove carpet, install 8,000 sq ft luxury vinyl plank | $X | X weeks |
| Painting | Interior repaint all tenant spaces | $X | X weeks |
Vague scopes like "cosmetic updates" or "bring up to current standards" invite scope creep and missed deadlines.
2. Fixed-Price or GMP Contract
Use a fixed-price or guaranteed maximum price (GMP) contract, not cost-plus. Include:
- Performance bonds (guaranteeing the contractor completes the work)
- Payment bonds (guaranteeing subcontractors and suppliers are paid)
- Liquidated damages clause (for every day past deadline, contractor pays $X)
3. Realistic Budget with Contingency
Build in 10-15% contingency. If the scope is $400,000, budget $440,000-$460,000. Allocate the contingency explicitly.
4. Contractor Vetting
Before hiring, verify:
- Financial stability and bonding
- Licenses and insurance
- References from prior projects completed on time
- Current project load (overbooked contractors deprioritize)
- Experience with tight-deadline projects
5. Permitting Timeline
Research permitting before Day 1:
- Contact local building department for typical permit turnaround times
- Identify which improvements require permits (roof, HVAC, electrical)
- Factor permit and inspection delays into the project schedule
- Consider a permit expeditor if the jurisdiction is slow
Timeline Stress Test
Before approving the improvement exchange, verify:
| Question | Method |
|---|---|
| Can the project finish by Day 170 (10-day buffer)? | Build a Gantt chart with task durations and dependencies |
| What is on the critical path? | Identify longest lead-time items (structural engineering reports, custom materials) |
| What if permits take 4 weeks instead of 2? | Model delay scenarios |
| What if materials are on backorder? | Confirm availability before Day 1; pre-order critical items |
| What if an inspection fails? | Build rework time into the schedule |
| Does the client have construction management capability? | If not, hire a professional project manager or GC |
Common Failure Points
| Failure | Cause | Prevention |
|---|---|---|
| Permitting delays | Jurisdiction has 12-week backlog; only 8 weeks remain for work | Obtain building department feedback before Day 1; reduce scope to non-permit work; hire expeditor |
| Contractor walkoff | Contractor takes a larger job and deprioritizes | Fixed-price contract with performance bond and liquidated damages clause |
| Scope creep | Client or GC adds work mid-project, pushing past Day 180 | Lock scope in writing; require formal change orders; reject any change that extends past Day 170 |
| Material shortages | HVAC units or flooring on backorder | Confirm material availability and order before Day 1 |
| Weather delays | Exterior work delayed by rain, snow, or extreme heat | Schedule exterior work early; build weather contingency days |
| Hidden structural problems | Water damage, foundation issues, hazardous materials discovered during construction | Conduct pre-acquisition inspection and Phase I environmental assessment; include contingency budget |
When NOT to Use an Improvement Exchange
| Condition | Reason |
|---|---|
| Construction window less than 60 days | Insufficient time for meaningful improvements |
| Improvement budget exceeds $500,000 or involves structural/mechanical changes | Major renovations require 6-18 months; 180 days is unrealistic |
| Client has no construction management experience and will not hire a GC/PM | High risk of mismanagement, delays, and disputes |
| Property is difficult to value or finance post-improvement | Lenders may resist; appraisal risk |
| Local contractor market is tight | Cost and quality compromises; scheduling unreliable |
Key Takeaways
An improvement exchange is one of the most tax-efficient structures for the right client and property. The critical success factor is disciplined planning:
- Only improvements completed by Day 180 count toward exchange value
- Use a reverse exchange structure when possible to maximize the construction window
- Lock scope, budget, and contractor before Day 1
- Stress-test the timeline against permitting, supplier, and weather risks
- Build a 10-day buffer before the Day 180 deadline

The Bottom Line
Improvement exchanges are tax-efficient when a below-market replacement property plus improvements equals the required exchange value, but only if advisors and clients are realistic about construction timelines and build in 10-15% contingency for inevitable delays.
