Must my replacement be rented right away to count as investment property?

The statute looks at why you took title, so a vacancy is evidence rather than a disqualification

Section 1031(a)(1) defers gain when property held for business or investment is exchanged for like-kind property 'to be held either for productive use in a trade or business or for investment'. The words 'to be held' look forward from the day you receive the replacement. Nothing in the statute or in Reg. section 1.1031(a)-1 requires rent to be flowing on that day.

The regulation goes further for land: 'unproductive real estate held by one other than a dealer for future use or future realization of the increment in value is held for investment'. A lot or farm parcel bought to hold can be a good replacement with no tenant ever.

What the IRS will not accept is a hope of appreciation layered over personal use. Rev. Proc. 2008-16 summarizes the Tax Court's Moore decision on two never-rented vacation homes: 'mere hope or expectation that property may be sold at a gain cannot establish an investment intent if the taxpayer uses the property as a residence.' The risk is what you do with the property while it is empty.

For a house, condo or apartment, Rev. Proc. 2008-16 replaces the intent argument with a calendar

The safe harbor applies to a dwelling unit, defined as real property improved with 'a house, apartment, condominium, or similar improvement that provides basic living accommodations including sleeping space, bathroom and cooking facilities.' If the replacement meets the qualifying use standards in section 4.02(2), the IRS 'will not challenge' that it was held for investment.

The standards are three. You own the unit at least 24 months immediately after the exchange. In each of the two following 12-month periods you rent it to another person at a fair rental for 14 days or more. And in each period your personal use does not exceed the greater of 14 days or 10% of the days rented at a fair rental, with personal use measured under section 280A(d)(2).

Under section 4.05, if you report an exchange expecting to meet the standards and later find the unit does not, you 'should file an amended return and not report the transaction as an exchange'. Outside the harbor you are back to proving intent on the facts. Moving in later is covered in how long to rent before moving in and how long to hold the replacement.

Repairs and marketing before the first lease do not break the exchange, and they also set your depreciation start

Repairs done to make the property rentable are consistent with holding it for productive use; see renovating the replacement. Paying for them from leftover exchange money is a separate question, answered in using exchange funds for repairs.

Depreciation runs on its own clock. Publication 527 says you place rental property in service 'when it is ready and available for a specific use', even if no one is renting it yet. Its own example: a house bought April 6, repaired, advertised in July and first rented September 1 is placed in service in July. Keep both dates in your file: intent runs from acquisition, depreciation from the day the unit was ready and offered.

Worked example: a condo closed March 1 and first rented June 1 clears the first year of the safe harbor easily

Hypothetical, round dates; run your own facts with your CPA. You close on a replacement condo on March 1, 2026. Painting and new flooring take six weeks, the unit is listed with photos and a rent figure on April 15, and a tenant signs a 12-month lease at market rent starting June 1.

The first 12-month period runs March 2, 2026 to March 1, 2027. The unit is rented at a fair rental for about 274 days of it, and your personal-use allowance is the greater of 14 days or 10% of 274, so 27 days. The second period must clear the same tests on its own numbers.

Publication 527's rule puts the placed-in-service date at April 15, when the unit was ready and listed. Had the tenant fallen through and the unit sat on the market all summer, the exchange analysis would not change, provided the listing stayed live and you did not move in.

Build the record while the property is empty, because that is when an examiner will look hardest

These facts carry intent and are easy to lose. Keep them with your exchange documents until the limitations period closes for the year you finally dispose of the replacement; see audit risk and records.

• Listing agreements, dated ads and rent comparables showing the asking rent was fair.
• Contractor invoices and dated photos showing the work was to make the unit rentable.
• Applications, showings and messages with prospective tenants, including those who declined.
• For land: zoning research, a hold plan, and any farming or parking lease offers.
• No family stays and no below-market lease to a relative; see renting to a child or parent.

A leased investment such as a DST interest takes the question off the table from the first day

The intent problem exists because a single property can be lived in. A beneficial interest in a Delaware Statutory Trust that owns leased real estate cannot. In the fact pattern of Rev. Rul. 2004-86, the trust's property is already leased to a tenant and the investors are treated as owning undivided fractional interests in it, so there is no period in which you could be using it personally.

That makes a trust interest a practical fit when part of the exchange should carry no occupancy question at all; see traditional DSTs and why a DST interest is like-kind. A trust interest is illiquid, carries the sponsor's and tenant's risks, and pays only what the property earns.
