Whether to rent out or sell a home you're moving out of is easier to decide once you weigh it across three axes: the chance you'll move back into it, the real economics of renting it out, and a tax deadline. It's worth combining all three rather than relying on just one.
- The three axes to weigh are the chance of moving back, the real economics of renting, and the tax deadline.
- If you expect to move back in a few years — say, after a job transfer — a fixed-term lease (teiki shakuya) that lets you set an end date is worth considering.
- Rental income needs to be viewed net of management fees, repair costs, fixed asset tax, and vacancy periods.
- If a mortgage is still outstanding, renting out the property may require your lender's approval.
- The ¥30 million special deduction for a primary residence has a deadline: you must sell by the end of the third year after you stop living there (as of 2026).
Weighing the chance you'll move back
The first thing worth considering is whether there's a realistic chance you'll move back into the home someday. If you expect to return in a few years — say, because of a job transfer — a fixed-term lease (teiki shakuya keiyaku), which lets you set a defined end date, is worth considering. Since the lease doesn't renew once its term ends, you have the reassurance of knowing the home will come back to you. If you don't expect to move back, on the other hand, the decision turns on whether you can justify holding onto the property on economic grounds.
Estimating the real economics of renting, realistically
If you're considering renting the property out, don't judge it on the headline rent alone. In practice, you need to net out management fees if you outsource management, repair costs as the property ages, fixed asset tax that continues regardless of whether it's occupied, and the fact that you earn nothing during vacancies — and look at the real, bottom-line economics. Deciding to rent based on the surface-level rent figure alone can leave you with less in hand than expected. The effect of an extended vacancy in particular tends to get overlooked, so it's worth building in a margin when you estimate it.
A note if you still have a mortgage
A mortgage is, in principle, a loan made on the assumption that you'll live in the home yourself. That means if you still have a mortgage outstanding, you need to get your lender's approval before renting the property out to someone else. How lenders handle temporary rentals for unavoidable reasons, such as a job transfer, varies by institution, so it's reassuring to check with them as soon as you start considering the idea. Selling a home with a mortgage still outstanding is a separate topic worth understanding on its own.
The tax deadline
The ¥30 million special deduction available when you sell your primary residence comes with a deadline: you need to sell by the end of the third year after you stop living there (as of 2026). If you rent the property out for an extended period before selling, you risk missing this deadline and losing the ability to use the deduction.

A note on selling after a period of renting
If you sell after renting the property out for a while, with a tenant still in place, that's what's known as an owner-change sale (ōnā chenji). An owner-change property falls outside the options of a buyer who wants to move in right away, which narrows the pool of interested buyers compared to selling for owner-occupancy, and can make it harder for the price to hold up. How to approach selling a property that already has a tenant in place is a separate topic worth understanding in detail. Rather than reviewing the lease terms only once you start considering a sale, it's reassuring to set them up with a future sale in mind from the point you first start renting the place out.
Frequently asked questions
Can I rent out my home just for the duration of a job transfer?
Yes. If you expect to move back, a fixed-term lease is well suited, since you can set a defined end date. If you still have a mortgage, you'll need to check with your lender beforehand.
Is it better to rent or to sell?
There's no one answer. If you're renting, judge it by the real, bottom-line economics — including vacancy, repairs, and tax — and if you're not moving back, weigh that against the simplicity of selling and the deadline on the tax special deduction.
Does renting the property out for a few years before selling change the tax treatment?
The ¥30 million special deduction for a primary residence has a deadline — you need to sell by the end of the third year after you stop living there. Renting for an extended period can mean losing access to it, so it's worth checking with a tax accountant, based on the requirements as of 2026.
Summary
Whether to rent out or sell a home comes down to three axes — the chance you'll move back, the economics, and the tax deadline. Because the special deduction on your primary residence in particular comes with a deadline, it's worth not putting off the decision for too long.
