A job transfer, a move back to a hometown, or simply a change in life stage — these are the moments when many owners find themselves stepping away from a condo they own in Japan. At that point, most owners face the same fundamental asset decision: should you sell the unit or rent it out? This article walks through the costs, tax rules, and risk-management issues you need to understand before renting out a condo, from the owner's perspective.
This decision is distinctly Japanese. A Japanese mansion (マンション) — the local term for a concrete, multi-unit condominium building, not to be confused with the English word “mansion,” which means a large detached house — comes bundled with rules that have no direct equivalent in most Western housing markets: home-mortgage terms strictly tied to owner-occupancy, an annual tax return (kakutei shinkoku, 確定申告) that most salaried employees in Japan never otherwise have to file, and a narrow, date-driven window for a valuable capital-gains exemption. Get one of these wrong and a bank recall notice or a lost tax break can quietly erase your rental numbers. At INA&Associates, we support many owners' rental operations every day, and in our experience the biggest reason people misjudge this decision is looking only at the income, never the costs and risks on the other side of the ledger. So this article is deliberately candid about the downsides too.
Should You Rent Out Your Condo or Sell It? Where the Decision Starts
The first thing to understand is that renting and selling are not a simple better-or-worse contest — the right answer depends on your purpose and your time horizon. Do you expect to move back into the unit in a few years, or are you ready to let it go permanently? That single question tends to split owners into two very different paths.
When Renting Makes Sense
If there is a realistic chance that you or your family will move back in later, renting lets you earn rental income without giving up the asset. If the unit sits in a strong location with steady rental demand, holding onto it and renting it out can also support long-term wealth building. A property where time works in your favor is exactly the kind of property that suits renting.
When Selling Makes Sense
On the other hand, if you have no plan to move back and the unit's resale value is likely to decline with age, an early sale can be the more advantageous route — especially while you can still use the ¥30 million special exemption for the sale of a former primary residence (approx. $195,000 at 155 JPY/USD), discussed later, a deadline-sensitive tax break with no close parallel in most Western capital-gains regimes. Rent the unit out too long and you can miss that window entirely, in which case your take-home proceeds end up lower than if you had simply sold from the start.
How Much Does It Cost to Rent Out a Condo?
Before starting a rental operation, getting an accurate picture of the costs involved is the foundation of any income and expense plan. It helps to split the costs into three buckets: the initial costs incurred before you hand the unit over, the costs tied to finding and signing a tenant, and the costs that recur for as long as the unit is rented.
Initial Costs Before Renting the Unit Out
Before welcoming a tenant, professional house cleaning is essential — grime or plumbing issues you might not notice yourself can hurt first impressions at viewings. If wallpaper is torn or fixtures have aged, renovation or replacement should also be considered. Handing the unit over in excellent condition directly translates into a higher occupancy rate and a more defensible rent level. Unlike a basic move-out cleaning in many Western rental markets, Japanese tenants and leasing agents alike weigh visible condition heavily when comparing listings, making this preparation near-mandatory rather than optional.
Costs at the Leasing and Contract Stage
The brokerage fee paid to the real estate agent who finds your tenant is, as a rule of thumb, about one month's rent plus consumption tax. In some cases this fee can be offset using the reikin (礼金, “key money”) the incoming tenant pays — a non-refundable, one-time gratuity to the landlord that is a distinctly Japanese custom with no direct Western equivalent, unlike a refundable security deposit. On top of that, you may also incur costs for drafting the lease agreement and for re-keying the locks between tenants.
Costs That Continue While the Unit Is Rented
Once the rental period begins, the owner continues to bear repair costs whenever equipment breaks down, along with fixed asset tax and city planning tax (a Japan-specific second property tax layered on top of the fixed asset tax, unique to areas designated for urban planning), plus the building's own management fee and repair reserve fund. If you outsource management to a property manager, the management fee is typically around 5% of the rent as a rough benchmark. The main cost items are organized below.
| Cost Item | When It Occurs | Approximate Amount |
|---|---|---|
| House cleaning | Before renting | Varies by layout and size |
| Renovation / restoration to original condition (genjō kaifuku) | Before renting | Varies widely by condition |
| Leasing agent's brokerage fee | At tenant contract signing | About one month's rent |
| Property management fee | Ongoing, monthly, while rented | About 5% of rent as a benchmark |
| Building management fee and repair reserve fund | Ongoing, monthly, while rented | Varies by building |
| Fixed asset tax and city planning tax | Ongoing, annually, while rented | Varies by assessed value |
| Equipment repair costs | Whenever a breakdown occurs | Case by case, variable |
Note that the building management fee (kanrihi) and the repair reserve fund (shūzen tsumitatekin) are two separate, mandatory monthly charges under Japan's condominium ownership system, unlike a typical US or UK condo/strata arrangement where a single HOA or service charge usually bundles both together. With these figures in hand, always simulate your “take-home cash flow” — rent minus ongoing costs — before you start, rather than relying on gross yield alone.
Taxes on Rental Income and the Basics of the Annual Tax Return
Once you start a rental operation, taxes are unavoidable. Rental income is taxed as “real estate income” (fudōsan shotoku, 不動産所得), and as a rule you must file an annual tax return (kakutei shinkoku, 確定申告) every year. This is a genuinely Japan-specific burden: most Japanese salaried employees never file their own return at all, because their employer settles income tax automatically each December through a year-end adjustment (nenmatsu chōsei) — unlike the US, where employees routinely file their own annual return regardless of income source. Rental income breaks that automatic settlement and puts the filing obligation back on you, and overlooking it can mean an unexpected tax bill later.
How Real Estate Income Is Calculated
Real estate income is calculated by taking your total rental revenue and subtracting your necessary expenses. Necessary expenses include the property management fee, repair costs, fixed asset tax, casualty insurance premiums, depreciation, and the interest portion of any loan. Depreciation (genka shōkyaku) deserves particular attention: it is an expense that does not involve any actual cash outflow, which makes it an important lever for reducing your taxable income.
Main Items You Can Claim as Expenses
- Management-related costs, such as the property management fee and brokerage fees
- Equipment repair costs and restoration-to-original-condition (genjō kaifuku) expenses
- Fixed asset tax and city planning tax
- Casualty insurance premiums, such as fire and earthquake insurance
- Depreciation on the building and its fixtures
- The interest portion of any loan attributable to the rental
That said, the scope of what counts as a deductible expense, and how depreciation is calculated, follows detailed rules. If you are unsure, do not guess — check with a licensed tax accountant (zeirishi). Honestly, tax is one of the areas where rental owners in Japan most often stumble.
What Should Condo Landlords in Japan Watch Out For?
Protecting your asset value over the long term means addressing certain issues before you start operating the rental. Neglect them, and you risk losses that far exceed whatever short-term rental income you collect.
Converting from a Home Mortgage Requires Your Lender's Approval
A Japanese home mortgage (jūtaku rōn) is granted on condition that the property is your own primary residence. Converting it to a rental without notifying the bank is treated as a breach of contract, and the lender can demand immediate repayment of the entire outstanding balance in one lump sum. Where many Western lenders might treat an owner-occupancy clause as a minor compliance matter, Japanese banks enforce it as a hard contractual condition. If you have an unavoidable reason, such as a job transfer, consult your lender in advance to obtain approval or refinance into a loan product that permits renting.
Thoroughly Document the Unit's Condition at Move-In and Move-Out
Disputes over restoration to original condition (genjō kaifuku, 原状回復) are among the most common problems in Japanese rental operations. Take detailed photographs of the room's condition before a tenant moves in, so you can objectively compare it against move-out. Under Ministry of Land, Infrastructure, Transport and Tourism (MLIT, 国土交通省) guidelines, normal wear and tear (tsūjō sonmō, 通常損耗) and ordinary aging are, in principle, not the tenant's financial responsibility — considerably more tenant-protective than the security-deposit norms many US landlords are used to, where a broader range of wear can be charged back. Drawing a clear line on who pays for what before move-in is the key to avoiding disputes later.
The Home Mortgage Tax Credit Is Suspended During the Rental Period
While your home is rented out, you cannot claim Japan's home mortgage tax credit (jūtaku rōn kōjo, 住宅ローン控除). Even if you later move back in, the credit generally only resumes from the following year, and note that the total credit period itself is not extended to make up for the gap.
The ¥30 Million Special Exemption and Its Relationship to Sale Timing
When weighing whether to rent or sell your condo, one of the most consequential tax rules is the “special ¥30 million exemption for the transfer of residential property” (approx. $195,000 at 155 JPY/USD) — a capital-gains exemption available when you sell a former primary residence. Whether you understand this rule correctly can make a large difference to your final take-home proceeds.
Be Aware of the Exemption's Deadline
If you sell a condo that used to be your primary home, you can generally use this special exemption of up to ¥30 million (approx. $195,000) as long as the sale closes by “December 31 of the year that includes the date three years after you stopped living there.” The longer the rental period drags on, the more likely you are to blow past this deadline. Most Western capital-gains systems have no equivalent, deadline-triggered exemption of this scale tied to a former-residence conversion, which is exactly why international owners often overlook it.
Choosing to Rent Can Cost You the Exemption
This is the pitfall of the rental decision. What was meant to be “just a few years of renting” often stretches on until, almost without noticing, the deadline has passed. Losing the exemption significantly increases the tax on your capital gain, so at the moment you decide to rent, also map out an exit strategy: by when do you plan to sell? Because eligibility varies by individual circumstances, confirm applicability with your local tax office or a tax accountant.
Weighing the Pros and Cons of Renting Out a Condo
As an investment decision, it is important to soberly weigh the returns against the risks. If you start out looking only at the upside, an unexpected expense can leave you unable to keep the operation going. The pros and cons are organized below.
Main Advantages
- Rental income can cover holding costs such as fixed asset tax and insurance premiums
- A tenant living in the unit naturally keeps ventilation and water flowing, which avoids the deterioration risk of a vacant home
- If you expect to return after a job transfer, you can keep the asset while still earning income
- Depreciation and other items can, in some cases, allow for useful tax adjustments
Main Disadvantages and Risks
- The risk that unexpected costs will arise, such as equipment complaints or restoration-to-original-condition disputes
- The home mortgage tax credit is suspended for the duration of the rental period
- Holding costs continue to accrue even during vacancy periods, when income is zero
- Ongoing administrative burden, including filing an annual tax return every year
Renting vs. Selling, Side by Side
| Point of Comparison | Renting | Selling |
|---|---|---|
| Form of income | Ongoing rental income | A single lump-sum sale price |
| Ownership of the asset | Retained | Given up |
| Main risk | Vacancy, repairs, unpaid rent | Missing out on future price appreciation after the sale |
| Key tax point | Real estate income tax; mortgage tax credit suspended | Potential use of the ¥30 million special exemption (approx. $195,000) |
| Ongoing effort | Management and annual tax filing continue | Only required at the time of sale |
How to Choose a Property Management Company Without Making a Mistake
If you live far away or your main job keeps you busy, handling management entirely on your own is not realistic. That is exactly why choosing a trustworthy property management company can determine whether your rental operation succeeds or fails.
Confirm the Scope of Work You Can Outsource
How much can be outsourced — tenant recruitment, contract procedures, rent collection, complaint handling, move-out settlement — varies from company to company. Before signing, confirm concretely whether the scope of outsourced work matches the fee being charged. Choosing on price alone can leave you regretting the quality of service exactly when it matters most.
Will They Be Honest with You, as the Owner?
What we value most is whether a company is honest with you about the downsides and risks, not just the good news. A company that only ever tells you good news is not one you can rely on when trouble actually happens. Trust and honesty are the foundation of a rental business built to last. This is also a value we at INA&Associates hold central to how we operate every day.
INA's Perspective — Rental Management That Serves Both People and Assets
We do not see real estate as merely an income-generating device. Behind every unit is a tenant's life, and behind that is the asset and life of the owner who supports it. Rental management should aim not just at short-term yield, but at an outcome that everyone involved can genuinely accept over the long term.
The decision to rent out a condo is not a one-time choice — it is the beginning of an operation that continues for years afterward. What matters most is how you design the management, tax handling, and exit strategy after you begin. We are committed to walking alongside owners for the long run, telling you honestly about both the good and the bad, so you can protect your asset with confidence.
Conclusion
Renting out a condo, if properly prepared, can lead to stable long-term asset management — but misjudging the costs, tax rules, or risks can just as easily mean you never see the returns you expected. What matters is judging the decision on the full picture: not just the surface number of rental income, but ongoing costs, vacancy risk, and tax-related deadlines together.
On top of that, matters like your home mortgage terms and the deadline for the ¥30 million special exemption (approx. $195,000) depend heavily on individual circumstances. When in doubt, do not go it alone — consult a trusted professional or property management company. For further reading, see the ina-network category page as well.
Frequently Asked Questions
Is there a problem with my home mortgage if I rent out my condo?
Because a home mortgage is granted on the condition that the property is your own primary residence, converting it to a rental requires consulting your lender and obtaining approval. Converting it without authorization risks the lender treating it as a breach of contract and demanding immediate repayment of the entire loan in one lump sum. If you have a reason such as a job transfer, consult your lending bank first.
How do I set an appropriate rent when renting out my condo?
As a rule, rent is set in consultation with a real estate agent, based on comparable nearby properties, the building's age, the level of its fixtures, and its location. Setting it too high prolongs vacancy; setting it too low squeezes your returns. It is safer to request an appraisal from a management company with solid market knowledge and confirm the reasoning behind the number.
Should I manage the property myself, or leave it to a management company?
If you live far away or your main job keeps you busy, outsourcing to a property management company is the realistic choice. The fee is roughly 5% of rent as one benchmark, but in exchange the company handles tenant recruitment, complaint response, and move-in/move-out procedures on your behalf, which significantly reduces both your workload and your stress. Decide based on the balance between the scope of outsourced work and the fee.
Is rental income taxed?
Rental income is taxed as real estate income, and as a rule you must file an annual tax return every year. Management fees, repair costs, and depreciation, among other items, can be claimed as necessary expenses. Because the scope of allowable expenses and the depreciation calculation follow detailed rules, we recommend consulting a tax accountant if you are unsure.
What happens if I miss the deadline for the ¥30 million special exemption (approx. $195,000)?
If you can no longer use the exemption, the tax burden on your capital gain from the sale can increase substantially. If you are considering a future sale, stay aware of how many years have passed since you stopped living in the unit, and build your plan around selling within the exemption's eligibility window. Because eligibility depends on individual circumstances, please confirm applicability with your local tax office or a tax accountant.
