Duplexes, triplexes, fourplexes, and small apartment buildings are some of the most active assets in the 1031 exchange market. Investors in this space often use exchanges to consolidate multiple smaller properties into a single larger building, defer significant depreciation recapture, or transition into commercial real estate — all without paying taxes on the gain.
Qualifying Small Multi-Family Properties
Any residential rental property with two or more units qualifies for a 1031 exchange as long as it is held for investment. The number of units does not affect eligibility — a duplex and a 20-unit apartment building are treated the same way under Section 1031.
- Duplexes (2-unit)
- Triplexes (3-unit) and fourplexes (4-unit)
- Small apartment buildings (5–20 units)
- Mixed-use buildings with residential and commercial units
- Owner-occupied multi-family (if investment portion is exchanged separately)
Depreciation Recapture on Multi-Family Properties
Residential rental properties are depreciated over 27.5 years. If you have owned your duplex or apartment building for several years, you likely have substantial accumulated depreciation that would be recaptured at 25% upon sale. A 1031 exchange defers that recapture tax along with your capital gains, allowing your full equity to move into the replacement property.
Trading Up: Consolidation and Portfolio Growth
The most common strategy for small multi-family investors is consolidation — selling two or three smaller properties and exchanging into a single larger building. This reduces management complexity, often improves cash flow per dollar invested, and defers all taxes on the combined gain. We can coordinate simultaneous exchanges from multiple relinquished properties into a single replacement.
Owner-Occupied Duplexes and Mixed-Use Properties
If you live in one unit of a duplex or small multi-family building, the rules are more complex. Only the investment portion of the property qualifies for a 1031 exchange. The owner-occupied portion may qualify for the Section 121 primary residence exclusion. We can help you structure the transaction to maximize the benefit of both provisions.
