1031 exchanges and DSTs: deadlines, rules and the market

The 45-day and 180-day rules, identification options, how Delaware Statutory Trusts fit, and 2025 DST market data.

Short answer

A 1031 exchange lets an investor defer capital gains tax by selling investment real estate and buying like-kind replacement property. You must identify replacement property in writing within 45 days of the sale and complete the purchase within 180 days (or by your tax return due date, if earlier). A Delaware Statutory Trust (DST) is a fractional ownership structure that can qualify as replacement property, letting investors exchange into professionally managed real estate. DST equity raised reached about $8.41 billion in 2025.

Key takeaways

  • 45 days to identify, 180 days to close, both counted from the sale of the relinquished property.
  • You can identify up to 3 properties, or more under the 200% or 95% rules.
  • DST equity raised rose about 49% to ~$8.41B in 2025 (Mountain Dell Consulting).
  • Multifamily made up 58% of syndicated DST offerings at the end of 2025.

The core 1031 rules

45 daysTo identify replacement property in writingFrom transfer of relinquished property
180 daysTo complete the exchange (or tax return due date, if earlier)Same start date
Identification ruleHow it works
Three-property ruleIdentify up to three replacement properties of any value
200% ruleIdentify more than three, if their combined value is no more than 200% of what you sold
95% ruleIdentify any number, but acquire at least 95% of the total identified value

Identification must be in writing, signed, and delivered to an independent party such as your qualified intermediary.

What is a DST, and why do 1031 investors use it?

A DST holds title to one or more properties; investors buy beneficial interests. Because a DST can qualify as like-kind replacement property, it gives exchangers a way to move from active landlording into passive, professionally managed real estate, and to close within tight deadlines.

Planning an exchange
