¥166m choice in Tokyo: 100 m² small multifamily or coastal home?

I’m deciding between a 100 m² small multifamily and a similarly priced coastal home in Tokyo, around ¥166,000,000. The multifamily initially looks easier to maintain, while the home offers more control but could bring larger, irregular repair bills.

I’m comparing building reserves, insurance, energy use, tenant demand, vacancy risk and eventual resale liquidity. What tends to be missed after the first year, and what would you put on a practical pre-purchase checklist?
 
Don’t assume the multifamily is automatically simpler. It may spread some building costs, but tenant turnover, vacancies and management can create a steady stream of smaller tasks. First establish exactly what the shared reserves cover, their current balance, and whether major work is anticipated. For the coastal home, obtain property-specific insurance terms and inspect the exterior, drainage and exposed equipment rather than budgeting from averages.
 
That distinction between fewer large decisions and many small recurring ones is useful. I was treating maintenance almost entirely as an annual cost, not as workload. I also need to separate reserve contributions from repairs inside each rentable area. Would you evaluate tenant demand before the building condition, or reject a weak building first even if the location rents well?
 
Building condition first, because strong demand does not repair a deteriorating structure. But I’d assess both before making any offer: condition determines the likely capital burden, while demand tells you whether income can absorb it. Also test a vacancy scenario rather than relying on full occupancy. A 100 m² property may have concentrated risk if only a small number of tenancies produce the income.
 
I’d push back slightly: a technically sound multifamily in a weak rental pocket can still be the worse purchase. Condition can be priced; persistently limited tenant demand is harder to change. Compare realistic rents, likely turnover and the type of tenant each space attracts, then price the identified building work. The coastal home’s resale market may also be narrower, so “more control” does not necessarily mean an easier exit.
 
For energy, compare the actual systems rather than property labels. A detached coastal home may have more exposed surfaces, but a small multifamily can have several separate heating, cooling and hot-water systems to maintain. Ask for past usage where available and list the age and condition of each major unit. Replacement timing can matter more than one year’s consumption.
 
I’d make two schedules for each option: predictable annual costs and irregular events. Put reserve payments, routine management, insurance and normal servicing in the first. Put exterior work, equipment replacement, tenant turnover, vacancy and insurance deductibles in the second. Then stress the timing: what happens if two irregular items land in the same year? Insurance scope and resale assumptions should be checked locally rather than inferred from the asking price.
 
One more caveat on liquidity: don’t compare only how quickly each property type might sell. Compare who the likely buyer is and what information they will scrutinise. A multifamily buyer may focus heavily on occupancy, rents, expenses and deferred work; a coastal-home buyer may be more sensitive to condition, exposure and insurance. Keep the records now that would make either story credible later.
