We built the company we couldn't find.
Owner-operated, technology-first property management for the San Francisco Bay Area.
We couldn't find a property manager good enough — so we built one.
We're Bay Area property owners ourselves. When we went looking for a management company, we had a simple bar: treat our homes like they're yours, communicate like adults, and use technology that actually makes life easier.
We couldn't find one that cleared it. The traditional firms leaned on call centers, franchise playbooks, and the same off-the-shelf software as everyone else. So we built the company we wished existed — and the software to run it.
We don't buy off-the-shelf and call it innovation. We build.
Most property managers rent their software. We wrote ours.
The big names run their entire business inside platforms they rent — AppFolio, Buildium — and call it modern. But rented software is a cost with strings: a per-unit fee for every door, and a vendor forever nudging you toward its own upsells. It ends up in what you pay and how slowly things move.
We built our own. No licensing fees, no vendor pulling strings — so those savings and efficiencies get passed directly to you. It's how we hold a large Bay Area presence with a small, focused team, and stay close to what actually matters.
Your books, always accurate
Every expense is captured and reconciled the moment it lands, so your statements stay tax-ready. We even read your utility bills and recover the tenants' share — money most owners quietly absorb every month.
Rent increases, done right
Bay Area rent law is unforgiving. The local math, the official forms, and the timing rules are built into the software — so the increases you're entitled to are filed correctly, on time.
Your property, in real time
Rent collected, balances due, repairs, renewals — the moment it changes, it's in your dashboard. The same live numbers we work from, not a monthly PDF weeks after the fact.
Deductions that hold up
Move-in and move-out are photographed, dated, and signed, with a side-by-side record of what changed. A deduction isn't your word against theirs — it's documentation that stands.
Sign in minutes, never lose a tenant
Document management and e-sign are built in. A qualified applicant signs from their phone in minutes — no good tenant lost to slow paperwork, no vacancy left waiting.
Repairs that actually move
When something breaks, we run the whole chain — vendor bids, your sign-off, scheduling. Small problems get fixed before they turn into expensive ones, and tenants stay happy.
Someone always answers
Our AI receptionist answers calls and texts day or night — the night shift we built so no tenant hits voicemail. Every issue is logged, triaged, and routed to a real person.
When we needed a financial backbone, we vetted the field, chose a partner that met our bar, and integrated our own software directly into it — we partner where it serves you, and build where it sets us apart.
That efficiency goes straight into running your property — a big presence, a small team, and nothing between us and what matters.
Standards we won't compromise.
Owner-first
Your investment cared for, not just collected on.
Technology that works for you
Software we built, not software we rent.
Genuinely responsive
No call centers. No franchise. Real people who answer.
Transparent
Clear pricing, no mystery fees.

FounderMike Mann is a Bay Area property owner before he's anything else. When he couldn't find a management company he trusted with his own properties, he didn't go looking for a better one — he built it.
MarinOak runs on software Mike wrote himself — no off-the-shelf platform, no vendor in the middle. He leads both the company and the technology. The team stays deliberately small: every owner gets the kind of attention you'd expect from someone who manages his own properties on the same system.
