Is an 8% Gross Yield Actually Profitable? Reading Net Yield Instead
Written by：SUMIMOTO Inc.Editorial Policy
The yield you see first in an investment listing is almost always the gross figure: annual projected rent divided by the purchase price. It is easy to compare, and it excludes every cost of actually holding the property. Screening several properties from overseas on that number alone is how buyers get it wrong.
How do gross and net yield differ?
Net yield subtracts running costs from annual rent and divides by total investment including acquisition costs. Setting out what each calculation includes makes the gap self-explanatory.
What each figure accounts for
| Item | Gross yield | Net yield |
|---|---|---|
| Annual rental income | Included | Included |
| Management fee to the agent | Excluded | Deducted |
| Building management and repair reserve | Excluded | Deducted |
| Fixed asset and city planning tax | Excluded | Deducted |
| Insurance premiums | Excluded | Deducted |
| Vacancy periods and letting costs | Excluded | Factored in |
| Acquisition costs | Excluded | Added to the denominator |
Figures worth holding onto
- Gap between gross and net
- 1–2points
- Withholding on rent to non-residents
- 20.42%
Typical for a single condominium unit
Certain exceptions apply
How wide does the gap get?
For a single condominium unit the difference is commonly one to two percentage points, and it widens with building age and with the high-yield regional stock. A gross 8% dropping below a net 6% is not unusual.
What changes if you are a non-resident?
Rent received by a non-resident is in principle subject to withholding — with exceptions, such as an individual tenant renting as a residence for themselves or a relative. Appointing a tax agent for the annual return is standard practice. And even where the yen-denominated yield lands as projected, the return in your home currency still moves with the exchange rate.
Relevant provisions
- Income Tax Act, Article 161
- Consideration for the lease of real property located in Japan is treated as Japan-source income.
- Income Tax Act, Article 212(1)
- A person paying Japan-source income to a non-resident must withhold income tax and pay it to the state.
- Act on General Rules for National Taxes, Article 117
- A taxpayer without a domicile in Japan must appoint a tax agent and notify the tax office.
Common oversights and what to do instead
✕Comparing on gross yield and picking the unit with heavy management fees and reserves.
→Deduct running costs on the same basis for every candidate and rank on net yield.
✕Modelling on full occupancy, then running short of cash during a vacancy.
→Build the cash flow on a conservative vacancy rate and letting cost.
✕Leaving acquisition costs out of the denominator and overstating the yield.
→Calculate on total investment including agency fees, registration costs and taxes.
✕No withholding or tax agent arrangement until after letting had started.
→Confirm the tax treatment before purchase and set up the arrangement before the tenancy begins.
Before you commit
- Checked the monthly management fee and repair reserve
- Checked the annual fixed asset and city planning tax
- Checked the agent's management fee rate
- Tested the projected rent against local market rents
- Built vacancy and letting costs into the model
- Calculated yield on total investment including acquisition costs
- Confirmed the withholding position and tax agent arrangement
- Assessed the effect of currency movement on your home-currency return
Frequently asked questions
- Q. What net yield should you target?
- A. The benchmark shifts with district, property type and financing terms. Comparing several properties on identical assumptions is more useful than any single target figure.
- Q. Are high-yield regional properties a bargain?
- A. The gross figure looks strong, but vacancy risk and exit liquidity are the real questions. Weigh net yield alongside your assumptions on resale.
- Q. Will the repair reserve rise?
- A. It is often stepped up over time under the long-term repair plan. Check the plan and the current balance before buying.
- Q. How should you handle currency?
- A. Model the yen cash flow and the home-currency cash flow separately — that keeps the decision from drifting with the rate.
