Tokyo coastal 3-bed at ¥172,100,000 and ¥771,000/month — does the yield hold up?

If the ¥771,000 rent is not achievable or turnover is longer than expected, the margin could shrink quickly. I am looking at a 3-bed coastal home in Tokyo priced at ¥172,100,000; at that monthly rent, the headline gross yield is about 5.4%.

The property appears sound, but I still need evidence for the rental estimate and a clearer view of management charges, property tax, insurance and coastal maintenance. I have also allowed for vacancy, regular work and an occasional major repair. Would you rely on signed comparable leases or an existing tenancy before accepting the rent assumption, and which property records or cost statements would you request to test the projected net return?
 
The gross arithmetic works: ¥771,000 × 12 is ¥9,252,000, or about 5.4% of the price. I would scrutinise property tax, insurance and coastal wear before discussing an acceptable net yield. Those are property-specific enough that a generic percentage allowance can mislead.
 
Is ¥771,000 based on an existing lease, signed comparable deals, or an agent’s asking-rent estimate? At this price, the quality of that one input matters more than fine-tuning the maintenance allowance.
 
Also clarify what “coastal” means here. Salt exposure, wind and water risk can change maintenance and insurance costs considerably, but not every Tokyo property described that way has the same exposure. Building construction, elevation and exact location are missing.
 
I’d model tenant turnover separately from ordinary vacancy. A 3-bed at ¥771,000 has a narrower tenant pool than a typical apartment, so one move-out can mean both lost rent and a meaningful reset cost. Averaging everything into a smooth annual vacancy figure hides that lumpiness.
 
On the target return: I wouldn’t choose a net-yield hurdle until financing is added. An acceptable unlevered result can become uncomfortable if the loan payment is sensitive to rates or if repairs coincide with vacancy.
 
I partly disagree that financing comes first. Establish the property’s unlevered economics before allowing debt terms to make the return look better or worse. Start with collected rent minus management, tax, insurance, maintenance and realistic turnover costs, then stress the financing separately.
 
What exactly is the regulatory concern—ordinary long-term tenancy, intended short stays, or some restriction tied to the building? Those are different operating assumptions. Without that detail, “regulation risk” is too broad to price into the yield.
 
Good question. If the ¥771,000 assumes furnished or short-duration occupancy, I would not compare it directly with a conventional long-term rent. The management burden, turnover pattern and permitted use all need to match the income estimate.
 
The larger-repair reserve deserves a component list rather than one round number. For a house near the coast, exterior surfaces, roof, windows, drainage and mechanical equipment may not age together. A sound inspection today does not establish the timing of future cash calls.
 
Don’t overlook acquisition and eventual selling costs when deciding whether the investment compensates you, even though they are not part of annual net yield. A modest annual spread can disappear if the planned holding period is short.
 
That is useful, but I’d keep two outputs: annual operating yield on the full purchase price, and a holding-period return including entry, exit and financing. Combining them too early makes it hard to see whether the weakness is the property or the transaction structure.
 
For the annual case, ask for the actual property-tax basis and an insurance quotation for this address. Purchase price alone won’t reliably tell you either cost. I would also want to know whether any shared-road, seawall, access or common-area obligation attaches to the home.
 
To put a decision around it, run at least three rent cases: ¥771,000, a lower achieved rent, and a period with no rent after turnover. If the purchase only works in the first case, the 5.4% headline is doing too much work.
 
A further caveat: “management” often covers routine tenant contact but not every repair visit, leasing expense or turnover task. The proposed management agreement should show what is included rather than relying on a single percentage in the model.
 
I’d ask for evidence on how long comparable 3-bed homes remain available and whether they actually close near ¥771,000. The relevant comparison is similar location, size, condition and lease format—not a broad Tokyo rental average.
 
Following Amelia’s two-output approach, my hurdle would be expressed as a margin over a conservative alternative, not a universal net-yield number. This deal has concentrated vacancy and repair risk, so a merely positive cash flow would not be enough for me.
 
One refinement to my earlier financing comment: test payment coverage in the bad year, not just the average year. A turnover, a rent reduction and a major repair can overlap. Annual averages make that combination look safer than the cash account will feel.
 
Has the seller provided a rent history for the property itself? If it has never achieved ¥771,000, I would treat that figure as a marketing assumption until supported by comparable completed lettings. Existing history would also reveal seasonality and turnover frequency.
 
Insurance is the line I’d expect many buyers to understate, especially if they insert a generic Tokyo estimate before insurers assess the particular coastal location and construction. Get the scope as well as the premium; a cheap policy with important exclusions does not solve the risk.
