Buying in December Versus January: The Timing Decision

For a buyer whose primary motivation is a large current-year tax bill, the difference between closing on December 20 and January 10 can be an entire year of deduction timing. It is also the situation where buyers most often make an expensive mistake in the opposite direction.

Why the date matters

Depreciation generally begins when property is placed in service, meaning ready and available for its intended use. For a short-term rental that generally means available for booking, not the date of closing.

A property that closes on December 20 and is not listed until February is generally placed in service in the following tax year. The closing date alone does not secure the deduction.

That distinction is the trap. Buyers racing to close before year end sometimes achieve a December closing and a March listing, which produces the deduction in the following year anyway, with the added cost of a rushed acquisition.

What placing in service actually requires

The property has to be ready and available for its intended use. For a short-term rental, that generally means furnished, functional, permitted where a permit is required, and genuinely available for booking.

A listing that exists but is blocked for all dates is a weaker position than one accepting reservations. A property with no furniture is not available for its intended use regardless of what the listing says.

The practical implication is that if a December placement in service is the objective, the furnishing, photography, permitting and listing work has to be substantially complete before the closing rather than started after it.

Sequencing to actually achieve it

1. Confirm with your CPA, early, that a current-year deduction is worth the compression and what it is likely to be worth.
2. Get the property under contract with enough runway that furnishing can be ordered during escrow.
3. Order furnishing on a schedule that has it delivered and installed within days of closing.
4. Complete permitting and registration in parallel, since a property that cannot legally operate is not available for its intended use.
5. Book photography for the week of closing.
6. List and open the calendar before December 31.
7. Engage the cost segregation provider early enough that the study is complete before filing.

This is achievable and it requires the acquisition timeline to be built around it from the start. It is not achievable by finding a property on December 5.

The case against rushing

The purchase decision should be driven by the property, not by the calendar. A property bought at a poor basis in December to capture a deduction is a bad investment with a tax benefit attached, and the bad investment lasts far longer than the tax year.

We screen roughly a thousand deals a week and eliminate about 98%. A December deadline does not change the filters, and a client with a year-end motivation gets the same answer about a property that fails them.

The honest advice in many cases is that January is fine. A deduction taken in the following tax year is a timing difference, not a loss, and buying the right property in the first quarter beats buying the wrong one in December.

Bonus depreciation phase considerations

Bonus depreciation percentages have been subject to statutory phase-down schedules and legislative changes over recent years, which means the value of a first-year deduction has varied by year.

That variation is a genuine reason to discuss timing with your CPA specifically rather than applying general reasoning. In some years the difference between placing in service in one year versus the next has been material beyond simple timing.

Because these provisions change, this is not something to plan from a blog post, including this one. Confirm the current-year treatment with your CPA before making a timing decision that depends on it.

The alternative for existing owners

If you already own a short-term rental purchased in a prior year and never had a cost segregation study done, the look-back option may be more valuable than rushing a new purchase.

A study can generally be applied to a prior-year purchase without amending returns, through a change in accounting method with a cumulative catch-up adjustment claimed in the current year.

That produces a current-year deduction without buying anything, and for owners who have been depreciating conventionally it is frequently the largest single tax opportunity available to them. It is worth exploring before concluding that a December purchase is the only path to a current-year benefit.
