What Is an Improvement or Construction 1031 Exchange?

Written by The Realized Team | Aug 31, 2026

An improvement or construction 1031 exchange allows a real estate investor to defer capital gains taxes by using proceeds from the sale of a relinquished property to buy and improve a replacement property of equal or greater value. This process necessitates compliance with specific IRS rules and deadlines.

Understanding the Improvement Exchange Process

An improvement or construction 1031 exchange, also known as a build-to-suit exchange, involves selling an investment property and using the funds to purchase and enhance a new property. The goal is to elevate the replacement property's value to meet or surpass the value of the property sold. This strategy not only defers taxes but also customizes the property to better suit investment needs.

Key Steps and Rules

45-Day Identification: The investor must identify the replacement property and any intended improvements within 45 days of selling the original property.

180-Day Completion: The construction or renovations on the replacement property must be completed within 180 days. Only the improvements finished within this period qualify for the exchange.

Value Requirement: The combined cost of the replacement property and its improvements must be at least equal to the relinquished property's value to qualify for tax deferral.

Roles Involved

Qualified Intermediary (QI): Manages the exchange funds and ensures compliance with IRS regulations.

Exchange Accommodation Titleholder (EAT): Temporarily holds the title to the replacement property during the improvement process. This arrangement prevents the investor from owning both properties simultaneously, maintaining the exchange's validity.

Benefits of Improvement Exchanges

Improvement exchanges enable investors to use tax-deferred capital for enhancing replacement properties, potentially increasing their value and appeal. This strategy offers flexibility and personalized real estate investment opportunities, making it easier to find properties that meet specific goals and market needs.
