Will Reserve Fund Fees Spike? The Fixed Costs That Cut Into Yields on Older Condos
On September 29, the Ministry of Internal Affairs and Communications released the final results of the October 2025 census: a total population of about 122.97 million, down 2.5% from 2020, with Tokyo reported as the only prefecture to grow. Population flows shape rental demand in any investment area — which is exactly why the fixed costs that quietly build up after purchase belong in your yield estimate too.
You find a condo listed at a 5%-plus gross yield, but after purchase the monthly management fee and repair reserve fee go up, and the income that actually reaches your account keeps shrinking. On older buildings this is not unusual. In short, both fees are fixed costs that do not depend on the rent you collect, and reserve fees are often designed to be raised in steps as the building ages — which can move your net yield significantly.
This article explains the difference between the two fees, why reserve fees rise, a worked example of net yield after an increase, and the documents and provisions to check before you buy. The figures are illustrative assumptions; actual amounts and procedures vary by building and management association. Please confirm with the management company and a qualified professional before deciding.
What is the difference between management fees and repair reserve fees?
The management fee covers day-to-day upkeep: cleaning of the entrance and corridors, elevator maintenance, staff wages, and electricity for shared areas. The repair reserve fee is set aside for future major works such as exterior repainting, roof waterproofing and replacing water pipes. Both are paid monthly by the unit owner, and the obligation stays with the owner even when the unit is rented out.
For an investor, the key point is that both keep accruing while the unit is vacant. The longer a vacancy lasts, the heavier the impact on cash flow.
Why do repair reserve fees go up?
There are generally two ways to set the fee: a level-contribution method with a fixed amount from the start, and a stepped method that begins low and rises over time. The stepped method is often used at new-build stage to keep the initial monthly figure low, so later increases are commonly already built into the plan.
In older buildings, rising material and labor costs, faster-than-expected deterioration or a shortfall in the reserve can lead the owners' meeting to approve an increase or a one-time levy. Because increases are decided by resolution, a single owner generally cannot block one, so your income projections should assume it may happen.
Worked example (purchase price ¥20M, annual rent ¥1.08M assumed)
- Gross yield
- 5.4%
- Net yield (current reserve fee)
- 3.8%
- Net yield (after increase)
- 2.9%
- Extra cost per year
- 180,000yen
Annual rent ÷ purchase price
After fees, reserve and property tax
Reserve fee assumed to rise from ¥10,000 to ¥25,000 a month
¥15,000 × 12 months
How much does an increase change your yield?
The example below assumes a purchase price of ¥20 million, monthly rent of ¥90,000 (¥1.08 million a year), a management fee of ¥10,000 a month, a repair reserve fee of ¥10,000 a month and fixed asset and city planning tax of ¥80,000 a year. It excludes vacancy loss, property management fees, agent fees and income tax, so real take-home income will be lower.
Before and after a reserve fee increase (illustrative, ¥10,000 units)
| Item | Before | After (reserve fee ¥25,000/month) |
|---|---|---|
| Annual rent income | 108 | 108 |
| Management + reserve fees (annual) | 24 | 42 |
| Fixed asset & city planning tax (annual) | 8 | 8 |
| Annual net income | 76 | 58 |
| Net yield on purchase price | 3.8% | 2.9% |
The increase alone takes net yield from 3.8% to 2.9%, about 0.9 points. Even with an unchanged gross yield, a change in fixed costs can shift the economics of the investment considerably.
Relevant laws and guidance
- Act on Building Unit Ownership, Article 7
- Claims the management association holds against owners, such as management and reserve fees, are generally treated as carrying a statutory lien.
- Same Act, Article 8
- Claims relating to common areas can generally be pursued against a successor to the unit, meaning a buyer may be asked to cover a prior owner's arrears.
- Same Act, Article 18
- Matters concerning the management of common areas are, as a rule, decided by resolution at the owners' meeting.
- MLIT Guidelines on Condominium Repair Reserve Funds
- Government guidance on setting reserve amounts from a long-term repair plan and on how each contribution method works.
What should you check before buying?
Before buying, review the current management and reserve fees and any arrears stated in the explanation of important matters, the long-term repair plan, the reserve balance and the latest meeting minutes. In particular, look at when increases are planned in the repair plan and whether the balance is sufficient against it.
Common misses and fixes
✕Calculating yield from today's reserve fee and ignoring increases a few years later.
→Check planned increases in the long-term repair plan and test whether the numbers still work after them.
✕Buying in a building with a low reserve balance and being asked for a one-time levy at the next major repair.
→Check the reserve balance and the timing and estimated cost of the next major repair beforehand.
✕Leaving out fees that keep accruing while the unit is vacant.
→Hold enough cash to cover fixed costs through several months of vacancy.
✕Not reading meeting minutes and missing disputes over repairs among residents.
→Review two to three years of minutes for discussions on increases and repairs.
Pre-purchase checklist
- I checked the current fees and their revision history
- I checked when the long-term repair plan expects fee increases
- I confirmed the reserve balance is adequate against the plan
- I confirmed in writing with the management company that there are no arrears
- I read recent meeting minutes for repair and fee discussions
- I recalculated net yield using the post-increase fee
Frequently asked questions
- Q. Are reserve fees deductible as an expense?
- A. For a rented condo, the tax treatment of management and reserve fees involves judgment. Management fees are generally treated as expenses while reserve fees may be treated differently depending on their nature, so please confirm with a tax accountant.
- Q. Can I oppose a fee increase?
- A. Increases are decided by resolution at the owners' meeting, so a single owner generally cannot block one. You can, however, attend, vote and voice your opinion.
- Q. Are older buildings always more expensive?
- A. Fees tend to be higher as major-repair costs grow with age, but the contribution method and repair history vary, so each building needs to be checked.
- Q. What if a one-time levy is requested?
- A. If the reserve falls short, owners may resolve to collect a one-time levy. Checking the balance and the next repair plan before buying makes this risk easier to estimate.
