Key Takeaways
- The 3-Property Rule allows up to 3 identified properties of any value—the simplest and most commonly used method.
- The 200% Rule allows unlimited properties if total value does not exceed 200% of the relinquished sale price.
- The 95% Rule allows unlimited properties of any value but requires closing on 95%+ of identified value.
- Identification must be in writing, unambiguous (street address or legal description), and delivered to the QI within 45 days.
The 45-day identification period is the most critical and time-pressured phase of a 1031 exchange. The IRS provides three rules for identifying replacement properties—understanding how they work and when to use each one is essential for exchange success.
The 3-Property Rule
Under the 3-Property Rule, the investor may identify up to three potential replacement properties of any value. This is the most commonly used identification method because of its simplicity. The investor identifies three properties in writing to the QI; they must ultimately close on at least one of them. Best practice: identify three properties ranked by preference—the primary target, a backup, and a safety net. This provides flexibility if the primary target falls through due to inspection issues, financing problems, or seller withdrawal. The identification must include unambiguous property descriptions: street address, legal description, or other clear identifier. Vague descriptions (e.g., "a property on Main Street") may be challenged by the IRS.
The 200% Rule
Under the 200% Rule, the investor may identify any number of properties, provided their total fair market value does not exceed 200% of the relinquished property's sale price. Example: If the relinquished property sells for $500,000, the investor can identify properties totaling up to $1,000,000 in combined value. This allows identification of four, five, or more properties as long as the aggregate value stays within the 200% cap. This rule is useful when the investor is considering several smaller replacement properties (e.g., selling one $500,000 property and potentially replacing it with two $400,000 properties). The risk: if the combined identified values exceed 200%, the identification fails entirely—not just the excess properties. Careful value estimation is essential.
The 95% Rule
Under the 95% Rule, the investor may identify any number of properties of any total value, provided they actually acquire 95% or more of the total identified value. Example: If the investor identifies $2,000,000 in replacement properties, they must close on at least $1,900,000 (95%). This rule is rarely used because it requires closing on nearly all identified properties—leaving almost no flexibility. It is primarily useful for large portfolio exchanges where the investor intends to acquire all identified properties. For most individual investors, the 3-Property Rule provides sufficient flexibility with the least risk. The 200% Rule is a useful fallback for multi-property replacements. The 95% Rule should be avoided unless the investor has high certainty of closing on all identified properties.
| Rule | Number of Properties | Value Limit | Closing Requirement | Best For |
|---|---|---|---|---|
| 3-Property Rule | Up to 3 | No limit | At least 1 | Most investors; simple and flexible |
| 200% Rule | Unlimited | ≤200% of relinquished value | At least 1 | Multi-property replacement strategies |
| 95% Rule | Unlimited | No limit | ≥95% of identified value | Large portfolio exchanges with high closing certainty |

Common Mistakes to Avoid
Identifying more than three replacement properties without checking the 200% Rule
Consequence: If the total value exceeds 200% of the relinquished property, the taxpayer falls to the 95% Rule—which requires acquiring nearly all identified properties or the entire exchange fails
Correction: Before submitting the identification list, verify compliance with either the Three Property Rule (3 or fewer) or the 200% Rule (aggregate value ≤ 200%); avoid triggering the 95% Rule
Making vague or incomplete property identifications in the 45-day identification letter
Consequence: The IRS requires unambiguous identification—vague descriptions (e.g., "a property in Dallas") may disqualify the identification, causing the exchange to fail
Correction: Identify properties using legal descriptions or street addresses; submit the identification in writing to the Qualified Intermediary with clear, unambiguous property descriptions
