I’m Chris. I run Woosung Management LLC, a real-estate operating company based in the USA. We own and operate a large rental portfolio: properties across multiple LLCs, mostly seller-financed, with a mix of long-term rentals, short-term rentals, and the occasional flip.
In 2024 we grew the portfolio by roughly 10x in twelve months. It was exciting. It was also nearly the end of us. We were managing 200+ leases in three Google Sheets, a folder of PDFs on Google Drive, and a slack channel called “stuff to remember.”
We missed a balloon payment by two weeks because nobody had it on a calendar. We almost lost a property tax exemption because the renewal email got buried. We sent a lender a P&L stitched together from four spreadsheets at 2 a.m. We were winning the deals and losing the operation.
So I did what any sleep-deprived operator does: I started building. First it was a spreadsheet template. Then a Python script to amortize seller-financed notes. Then a database. Then a web app. Then James, an AI assistant who could read our data and answer the questions I kept asking on long drives.
Why seller financing is the whole point.
Most real-estate software treats seller financing like a footnote. For us, it’s the main story. About 90% of our deals are seller-financed. We send LOIs. We negotiate terms in plain English. We track balloons, partial payments, and modifications. We close deals that don’t involve a single bank.
So when we built Command Center, seller financing was front and center. The LOI generator, the term-sheet templates, the note tracker, the lender package: all of it was built for the way we actually close deals. If it’s good enough to run our portfolio, it’s good enough to run yours.
This software runs our portfolio first.
That sentence is important. Command Center is not a side project. It’s the operating system for Command Center. Every feature is in here because we needed it. Every workflow is here because we use it. Every alert is here because we missed something once and never wanted to miss it again.
The flip side: we’re biased toward features that matter for portfolios that look like ours. Mid-Midwest. 1 to 1,000 units. Mostly long-term residential, some STR, some small commercial. Seller-financed-heavy. If that sounds familiar, you’re going to love this tool. If you’re running a 10,000-unit institutional fund, we’re probably not the right fit yet.
What we’re not.
We don’t want to be everything. We don’t want to be your bank. We don’t want to be your tenant CRM. Today we’re focused on being the operating system above all of those tools, not replacing them.
We want to be the source of truth for your portfolio. The layer that sits above your bank, your accounting software, your tenant management, your legal docs. The thing you open every morning to answer the question “what do I own and what is it doing?”
What’s on the roadmap.
Based on user demand we may add rent collection in the future. Deeper bank integrations, more 3D tour features, an investor-facing portal, and a native mobile app are all on the list too. We’re going to take our time and build them the way we build everything else: because users asked for them and because we can do them well, not because someone wrote it on a Gantt chart.
If you’ve got a feature idea, tell us. We read every message. About half of what’s in the product right now came from beta users who said “wouldn’t it be nice if…”
