A house price tells you what it costs to buy the property. It does not tell you what it costs to keep it ready for your next visit.
Before setting a purchase budget, build a second budget for ownership. Start with the particular house and the way you intend to use it. A general estimate from a video or article cannot tell you which bills will apply to your address.
Build a worksheet with evidence beside each number
For every cost, record the amount, whether it repeats, who supplied the estimate, and when you checked it. Leave unknown amounts blank and label them “quote needed.” An unknown cost is a useful next question; treating it as zero hides the question.
| Budget category | Evidence to request |
|---|---|
| Local taxes and charges | Property-specific records and confirmation of which charges apply to you |
| Insurance | A quote for the property's condition and intended occupancy |
| Utilities and connectivity | Account terms, standing charges, and expected usage |
| Local care and administration | A written scope showing visits, reporting, mail, keys, and exclusions |
| Maintenance and seasonal work | Inspection findings and local quotes for relevant work |
| Professional support | A quote based on your ownership structure and actual needs |
| Visits | Your expected travel, arrival preparation, and cleaning costs |
Keep initial setup and renovations separate from recurring costs. Otherwise, a large first-year expense can make the annual comparison confusing.
Write down how you will use the house
How many trips do you expect to make? Will anyone else stay there? Will the property be empty between visits? Would you still want it if you received no rental income?
These questions are inputs to the budget. Give the same answers to the people quoting insurance, maintenance, and management so their estimates describe the same situation.
If rental income is part of your plan, give it a separate worksheet. Confirm what is possible for the specific property before counting income toward affordability.
Separate the coordinator's fee from the work
“Management” can describe several different things. A quote might pay for administration, with a visit charged separately. Another might include regular visits but exclude repairs and contractor bills.
Ask for three examples: an ordinary quiet month, a month with an extra visit, and a month when a repair needs coordinating. Request itemised amounts rather than comparing headline fees alone.
Stress-test your own assumptions
Create a normal-year column and a difficult-year column. In the second, use a repair scenario based on the property's inspection, fewer personal visits, and any other uncertainty relevant to your plans. Ask which expenses continue even when you cannot travel.
There is no universal contingency percentage in this worksheet. A useful allowance should reflect the house's condition and the work you know might be needed.
Keep the underlying costs in yen, alongside any dollar conversion you use for planning. Record the exchange-rate assumption so you can change it without rebuilding the worksheet.
Decide what you still need to learn
The result should be a short list of unanswered questions, not a deceptively precise total. Which quote would most change your decision? Which cost is uncertain because nobody has checked the house? Which service can you not yet find locally?
Those are the questions to resolve before your next step.
