Exchange Type
1031 Improvement Exchange
Also called a Build-to-Suit Exchange — an Improvement Exchange lets you use exchange funds to enhance, build, or improve a replacement property, maximizing your tax deferral by reinvesting every dollar.

What is a 1031 Improvement Exchange?
A 1031 Improvement Exchange — also known as a Build-to-Suit Exchange — is a type of 1031 Exchange that allows investors to use exchange funds to enhance, build, or improve a Replacement Property. Rather than simply acquiring an existing property, this structure lets you custom-build or renovate to your exact investment specifications.
Why an Improvement Exchange?
In a traditional 1031 exchange, if the replacement property costs less than the relinquished property, the difference becomes taxable "boot." With an Improvement Exchange, construction and enhancement costs count toward the reinvestment total — allowing investors to reinvest all proceeds into a custom or improved asset and avoid boot entirely.
Step-by-Step Process
Select a Qualified Intermediary
The QI holds all sale proceeds, manages payments for the replacement property acquisition, and funds approved improvement costs.
Sell the Relinquished Property
Proceeds transfer directly to the QI. The investor cannot receive or control any funds at this stage.
Identify Replacement Property (Day 1–45)
Identify the property you intend to purchase and improve within 45 days. Also outline improvement plans and estimated costs.
Complete Purchase & Improvements (Day 1–180)
The QI funds both the property acquisition and approved improvement costs as work progresses — all within the 180-day window.
Title Transfer
Once improvements are substantially complete, the QI transfers title of the improved property to the investor, finalizing the exchange.
Advantages
Full Fund Utilization
Reinvest every dollar into property enhancements — no taxable boot from unspent proceeds.
Custom-Built Property
Create or enhance property to exact specifications — ideal when the market lacks ready-made options that fit your needs.
Wider Property Selection
Consider properties that currently lack desired features but can be improved or built out to suit your investment strategy.
Potential Cost Savings
Acquiring underdeveloped land or structures and adding improvements can be more cost-effective than buying a finished asset.
Critical Timing & Value Requirements
Timeline Compliance: All improvements must be substantially complete within the 180-day exchange period. Work with contractors experienced in exchange timelines to avoid disqualification.
Value Requirement: For full tax deferral, the replacement property's value after improvements must equal or exceed the sale price of the relinquished property.
QI Manages All Funds: Every dollar — for property purchase and improvements alike — flows through the Qualified Intermediary. The investor has no direct control over funds during the exchange period.
