Scenario Library / Short-Term Rental Scenarios / Scenario: Converting a Long-Term Rental to a Short-Term Rental

This page describes a composite hypothetical. It is not a real client or a real result. Dates and amounts are assumptions, and the treatment of a mixed year has technical points to confirm with an advisor.

The Scenario in Brief

An investor owns a rental house that had a long-term tenant for several years. The tenant's lease ends in March, and the investor decides to furnish the house and rent it on a nightly basis starting in May. The investor wants to know how the change affects the tax return for the year of conversion and what records to start keeping.

Assumptions Used

The Average Stay

The advisor would compute the average period of customer use for the short-term period.

ItemAmount
Days of customer use, May through December150
Number of stays40
Average period of customer use3.75 days

The average is below seven days for the short-term period, which suggests the activity may not be a rental activity for passive purposes in that period. The advisor would explain that the treatment of a year that includes both long-term and short-term periods has technical points, and would suggest conservative documentation. The investor's records for the earlier months, including the lease and rent history, would be retained separately.

Vacancy and Setup Time

The month of April was a transition period. The advisor would explain that the property remained available for rental in the sense that the investor was preparing it, but the setup work could also affect when depreciation on the new assets begins. The furniture and appliances are separate assets, and each has its own placed-in-service date, which the investor sets when the property is ready for guests and the assets are available for use. Keeping the purchase dates, delivery dates, and the date of the first booking would support the placed-in-service dates.

Furnishings and Equipment

The 30,000 dollars of furnishings would generally be 5-year or 7-year property. If bonus depreciation at 100 percent is available, the entire amount might be deductible in the year, subject to limits. If not, it would be depreciated over the recovery periods. If the activity were passive, the deduction would be part of the passive loss. The advisor would also mention that small items may be eligible for a de minimis safe harbor election if they meet the requirements.

The Building's Recovery Period

The advisor would discuss whether the recovery period for the building changes because of the change in use. Many practitioners treat short-term rentals with transient use as nonresidential real property with a 39-year recovery period, but positions vary. If a change is appropriate, it may require an accounting method change. The advisor would look at the facts and the guidance and would not assume a change without analysis.

Participation Records

The advisor would emphasize the participation log. The investor's setup time, including furnishing, photographing, creating listings, and setting up pricing, could count as participation if performed by the investor and documented at the time. Contractor time should also be tracked to test the comparison with the cleaner. On the assumed hours, the investor's 120 hours would exceed the cleaner's 90, which might support the third test if the other requirements are met. The advisor would remind the investor that investor-type activities such as researching the market would not count.

Suspended Losses from the Long-Term Period

If the property produced suspended passive losses while it was a long-term rental, the advisor would explain that the change of use does not automatically release them. They would generally remain suspended until the investor has passive income or disposes of the property in a fully taxable sale. The advisor would confirm how the activity is defined and how the losses would be tracked.

Illustrative Effect

If the investor's net result from the short-term period were a loss of 15,000 dollars after furnishings expensing and depreciation, and if the loss were nonpassive, the federal tax effect at an assumed 24 percent rate would be about 3,600 dollars. If the loss were passive, it would be suspended. These figures are hypothetical.

Scenario Variations Worth Considering

If the average stay were nine days, the property would remain a rental activity for passive purposes. If the investor had converted in January, the year would be entirely short-term. If the cleaner spent more hours than the investor, the participation analysis would change. If the investor had a property manager, the manager's hours would need to be considered.

Risks and Limits

What This Scenario Teaches

A conversion is a change in the facts of the activity, and the records should show the date and the reason. Starting the logs on the first day makes the year easier to support.

Questions to Bring to Your Advisor

  1. How should I treat the year of conversion?
  2. What should I do with my furnishings purchases?
  3. How should I document my hours and the cleaner's hours?
  4. What happens to my suspended losses?

Frequently Asked Questions

Does converting restart depreciation on the building?

Generally no. The building continues to be depreciated, though the recovery period should be reviewed.

Is the tax effect in this scenario a promise?

No. It is arithmetic on assumptions.
