Comparing Self-Managed vs. Managed Property Total Costs

When I bought my third rental unit, a property management company quoted me 5% of monthly rent plus a leasing fee equal to one month’s rent every time a tenant turned over. On a unit renting for 80,000 yen a month, that is 4,000 yen every month just for oversight, plus roughly 80,000 yen whenever someone moves out. Multiply that across 9 properties over 15 years and you are talking about several million yen. So the question I get asked most often by new landlords is simple: is self-management actually cheaper once you count everything, or does it just feel cheaper because the costs are hidden in your own time?

I have managed all 9 of my properties myself since I started, so I have 15 years of real numbers to compare against what a management company would have charged. The honest answer is that self-management wins financially, but only if you are willing to trade your evenings and weekends for it.

What Property Management Companies Actually Charge

Most companies in my area charge between 3% and 5% of collected rent as a monthly management fee, and that usually does not include repairs, advertising for new tenants, or emergency call-outs. Add a leasing fee of one month’s rent per turnover, a renewal fee of around 10,000 to 20,000 yen when a lease renews, and markups of 15% to 20% on any contractor work they arrange, and the real cost creeps closer to 10% to 12% of gross rental income once everything is tallied. On a portfolio generating 7.2 million yen a year across 9 units, that is roughly 720,000 to 860,000 yen annually flowing out before you even think about vacancy or major repairs.

What Self-Management Actually Costs Me

My own costs look very different. I spend about 8 to 10 hours a month on routine tasks: rent collection follow-ups, coordinating cleaners between tenants, and answering the occasional maintenance text. During a turnover month that jumps to 20 to 25 hours because I am doing the walkthrough, listing the unit, screening applicants, and often repainting or fixing minor issues myself. I budget 3% of rental income for outside contractors I cannot handle alone (electrical work, major plumbing, roofing), plus another 2% for materials on the DIY repairs I do handle, things like replacing a kitchen faucet for 4,500 yen instead of paying a plumber 18,000 yen for the same job. All in, my out-of-pocket costs run about 5% to 6% of gross rent, roughly half of what a management company would charge.

The Hidden Cost Nobody Puts on a Spreadsheet: Time and Mistakes

Here is where self-management gets honest. In my first two years, I underpriced a rent renewal by about 8,000 yen a month because I did not check comparable listings carefully, which cost me nearly 96,000 yen over that lease term. I have also eaten the cost of a bad tenant screening decision once, which took four months and around 210,000 yen in lost rent and legal fees to resolve. A management company with experienced staff might have caught both of those earlier. So while my direct expenses are lower, my effective cost includes an education tax that decreases the longer you do this, but never fully disappears.

Running the Numbers on a Single Unit

Take one of my units renting at 90,000 yen a month, or 1,080,000 yen a year. A management company at 5% plus one turnover a year would cost around 144,000 yen annually (54,000 yen in management fees plus 90,000 yen leasing fee, averaged for turnovers that happen roughly every 18 months). My self-managed cost on the same unit, including materials, occasional contractor help, and an allowance for my own time valued conservatively at 1,500 yen an hour for the 100 or so hours a year I put in, comes to about 135,000 yen. The gap is smaller than people expect once you actually value your own labor honestly, which is the calculation most landlords skip.

Where Each Approach Actually Wins

Before deciding, I ask new landlords to walk through this checklist honestly:

• Do you live within a 30-minute drive of the property? Self-management gets much harder beyond that.
• Can you realistically spend 10+ hours a month on this, especially during turnover season?
• Do you have basic repair skills, or a reliable handyman you trust at fair rates?
• Is this your only source of income, where a vacancy of even one month creates real financial pressure?
• Do you own more than 5 units, where the time cost starts to compound quickly?

If you answered no to two or more of these, a management company’s 10% fee is often worth it, especially for landlords who live far from their properties or hold full-time jobs elsewhere. I have colleagues managing properties 200 kilometers from home who pay the fee gladly because the alternative is losing a full day of travel for every minor issue.

My Verdict After 15 Years

For someone local, hands-on, and willing to learn basic repairs, self-management saves roughly 4% to 6% of gross rental income a year once you account honestly for mistakes and your own time. On my 9 properties, that gap has added up to a meaningful amount over 15 years, enough to fund two additional down payments. But I would not recommend it to everyone, only to landlords who genuinely enjoy the hands-on side of the work. That’s the approach I use across all 9 of my properties, and it is the reason I still pick up a wrench on a Saturday morning instead of calling someone else to do it.
