Comparing the Cost of In-House vs. Outsourced Property Management

When I bought my first rental property 15 years ago, a local management company quoted me 5% of monthly rent plus a leasing fee equal to one month’s rent every time a tenant moved out. That sounded reasonable on paper until I scaled it across what eventually became 9 units. At that size, outsourcing everything would run me close to 900,000 yen a year in fees alone, before a single repair was made.

I decided to handle most of it myself instead, and after a decade and a half of running both models side by side (I still outsource one property), I can tell you exactly where self-management actually saves money and where it quietly costs you more than people admit.

What Property Managers Actually Charge

Most companies I’ve gotten quotes from over the years land around 5% of monthly rent for basic collection, tenant communication, and vacancy listing. On a unit renting at 70,000 yen a month, that’s 3,500 yen monthly, or 42,000 yen a year, per unit. Then add a leasing fee (typically one month’s rent) whenever a tenant turns over, plus a renewal handling fee of roughly 20,000 to 30,000 yen every two years. Even with low turnover, a single unit can end up costing 100,000 yen or more a year in management fees. Multiply that across 9 properties and the total climbs past 900,000 yen annually, and that’s before any actual maintenance happens.

What It Actually Costs Me To Self-Manage

I don’t write a monthly fee check, but my time isn’t free either. I estimate I spend around 6 hours a month per property on tenant calls, rent tracking, and coordinating upkeep, which comes to about 54 hours a month across all 9 units. Valued at even 2,500 yen an hour, that’s 135,000 yen a month, or 1.62 million yen a year. On paper, that number looks worse than outsourcing. But a large share of those hours are things I’d be doing anyway as a hands-on owner, and the physical repair work, the part a management company would just subcontract out at a markup, I do myself and bill nothing for it.

The Repairs Are Where the Real Money Is

This is the part most cost comparisons miss entirely. When a management company handles a repair, they typically tack on a 10 to 20 percent coordination fee on top of whatever the contractor charges. A water heater replacement that costs 80,000 yen from a plumber becomes 96,000 yen or more once that markup is added. I’ve replaced three water heaters myself over the years, spending around 35,000 yen each in parts plus a weekend of my own labor. Add in drywall patching, flooring repairs, and basic plumbing fixes, and I estimate I’ve avoided over 2.4 million yen in repair markups across 15 years simply by doing the work myself instead of letting a company hire it out.

When Outsourcing Actually Makes Sense

I’m not against management companies. I still use one for a single property that’s two hours from where I live, because the drive time alone would erase any savings. If you own fewer than 3 properties, live far from them, or work a demanding full-time job with no flexibility, that 5% fee is often worth every yen. In my experience the break-even point sits around 4 to 5 properties within a reasonable drive: below that, your hourly time cost usually beats the management fee, and above it, your time gets stretched too thin to do quality work.

Cost isn’t the only factor, and I’d be lying if I said self-management is purely a numbers game. When I started, it took me nearly 2 years to feel confident running background checks, drafting lease renewals, and handling the paperwork around a guarantor company on my own. A management company already has those systems built, and for a new landlord that head start can be worth paying for even if the raw yen math favors self-management. I still keep a checklist taped inside my filing cabinet with every document a new tenant needs, because missing one form early on cost me a full month of vacant rent while I sorted it out.

A Quick Checklist Before You Decide

• Calculate your true hourly rate, not just the management fee percentage
• Count how many hours a month you can realistically give without burning out
• Get quotes on 2 to 3 recent repairs to see the markup a manager would add
• Factor in tenant screening and legal paperwork, which take longer to learn than repairs
• Consider a hybrid approach: self-manage day-to-day but outsource during a busy season

My Break-Even Math After 15 Years

Across all 9 properties, I estimate self-management saves me somewhere between 700,000 and 1 million yen a year compared to full outsourcing, once you subtract a fair value for my time and account for the repair markups I avoid. That’s not free money, it’s money earned from weekends spent under sinks and evenings spent answering tenant texts. But it’s also the money that let me buy property number 7 in cash instead of taking out another loan, which is the kind of trade-off no percentage fee on a quote sheet ever shows you.

If you’re weighing this decision yourself, don’t just compare the headline percentage, run the repair markup and your real hourly cost side by side. That’s the comparison that actually matters, and it’s the one that’s kept all 9 of my properties profitable without a manager on payroll for every single one of them.
