A new real estate investment brings dozens of questions without ready-made answers.
- Will this property perform better as an STR, student housing, or a hotel?
- What kind of welcome pack maximizes RevPAR for this specific guest profile?
- How does a change in the business model affect bank covenants at this level of financing?
- What does the cash flow look like if construction is delayed by three months?
Most investors answer these questions using intuition and a single Excel model that calculates one scenario at a time. Origami Effect builds a system that computes all scenarios simultaneously — and keeps a close eye on costs once the decision is made.
Two stages. Four tools. One ecosystem.
A real estate investment has two critical moments — before and during. Before: which decision is the right one. During: whether execution is going according to plan. Origami Effect handles both.
Stage One — Investment Decision
Artemis — dozens of scenarios before a single decision is made
Artemis is an MFO-class financial model built specifically for real estate.
It doesn’t just accept a single set of assumptions — it simulates the full physics of different business models for the same property and compares them side by side.
Business models within a single model
The same 80 rooms. Four completely different strategies — and four completely different financial outcomes.
STR (Short-Term Rental) — variable revenue depending on occupancy and ADR, high operational opex, sensitivity to seasonality and platforms. Artemis models various occupancy scenarios, different ADR levels broken down by seasons, and diverse management cost structures.
Student housing — stable revenue, long-term contracts, low opex, but limited pricing flexibility and specific capex requirements. The model accounts for academic cycles, vacancy periods, and infrastructure demands.
Hotel with a welcome pack — a model that changes the financial picture not by altering the room rate, but through the structure of the packages. Artemis simulates different welcome pack variations — breakfast, transfer, parking, spa — and calculates the impact of each variant on RevPAR, margin, and cash flow. Which package maximizes the result for this guest profile and location?
Hybrid model — a mix of STR, long-term rental, and additional services. Artemis models the optimal allocation structure for a specific property and market.
Build To Sell — a model where revenue is not a rental stream but a one-time sales event. Artemis models the development schedule, construction costs spread over time, projected unit sales prices based on finishing standards and market conditions — and above all, the cash flow, which remains negative for most of the investment period and must be reconciled with the financing schedule. When does the project start generating a surplus? What does the IRR look like under various sales price scenarios and implementation schedules? What happens to liquidity if sales move slower than expected?
Monthly rental and mixed-use — apartments, commercial spaces, or any combination thereof within a single property. Artemis models the revenue structure broken down by unit types, square footage, and rental rates. It factor in vacancies, lease renewal cycles, tenant turnover costs, and technical maintenance expenditures.
CaPex and OpEx in every variant
Every business model carries a different capex profile — a different fit-out standard, different technical infrastructure, different equipment. Artemis models CaPex separately for each variant and shows how the difference in investment outlays translates into IRR, payback period, and bank covenants at the same level of financing.
OpEx is modeled down to the exact cost category — operations, utilities, marketing, management, maintenance. Changing a single variable instantly recalculates across the entire model.
Risk scenarios
For each business model, Artemis generates risk variants — what happens when occupancy is 20% lower than assumed, when construction costs rise by 15%, or when the interest rate changes by 100 basis points.
Stress tests and “black swan” scenarios for every variant. The investor sees not only which model is best in the baseline scenario — but also which one is the most resilient when things go wrong.
Archiving and comparability via Clio
All calculated scenarios are sent to Clio, where they are archived with timestamps, authors, and full assumptions. Compare STR vs. student housing vs. hotel at the balance sheet, P&L, and cash flow levels — in a single PDF or PowerPoint, without opening a single .xlsx file. The history of every model version is accessible at any moment.
How do you know why occupancy assumptions were changed three weeks ago? In a traditional approach — you don’t.
In the Origami Effect ecosystem, every single change is saved. The decision has a history.
Unlimited scale — one ecosystem for the entire portfolio
Artemis contains the profile of a single property — with its own physics, CaPex structure, business model, and scenarios. This is intentional. Each asset has its own dedicated model that calculates only its unique logic — without the compromises that come from averaging different assets in a single spreadsheet.
Clio consolidates data from all properties into one central database. Whether it’s dozens of real estate assets, twenty, or a hundred — Clio gathers results from every Artemis model and assemblies them into a single, cohesive portfolio view. The master report for the investor shows all properties side by side — with the ability to drill down to a single property, a specific construction phase, or a particular cost category.
Echo operates in an analogous way. It can log invoices for a single property or handle an entire portfolio simultaneously — with every invoice automatically assigned to the correct asset, phase, and budget category. The aggregated view shows total costs and budget execution for the entire portfolio. The individual view shows the details of a specific investment or construction site.
Scale does not change the architecture. Adding another property simply means adding another Artemis model and another data source in Clio — without any system overhaul.
Stage Two — Investment Execution
Echo — real-time construction cost oversight
Once the investment decision is made and construction begins, a new problem arises: how to control costs when invoices flood in from dozens of contractors, suppliers, and subcontractors — at different times, across various categories, and for different project phases?
Echo logs every construction invoice at the exact moment of receipt and automatically assigns it to the proper stage, budget category, and line item. No manual data entry. No waiting for a monthly report from the site manager.
Data from Echo goes instantly into the database and is cross-referenced with the budget from Artemis.
At any given moment, the investor can see: how much has been spent to date, how much remains in each category, where deviations occurred, and how they impact the project’s total capex.
What Echo monitors on the construction site
Construction works broken down by stages and categories — structural work, installations, finishing, landscaping. Each category has its own budget and invoice history.
- Suppliers and subcontractors — who billed how much, how much has been paid, how much is outstanding, and whether payment deadlines are being met.
- Changes and additional works — each change order is budgeted separately and tracked independently from the original cost estimate. The investor can immediately see if additional works fit within the contingency reserve or require a decision to increase financing.
- Currency exposure — for foreign material purchases, Echo logs currency obligations and shows their impact on total capex at current exchange rates as well as scenario rates.
Construction alert system via Clio
Clio monitors data from Echo according to defined rules and reacts whenever something needs attention: a budget category exceeded by more than a set threshold, a phase lagging behind schedule, an unassigned invoice, or an overdue payment to a contractor. Alerts reach the investor wherever they are — WhatsApp, Teams, Discord. Not when someone finds the time to check, but the moment the event occurs.
Budget execution report
Clio automatically generates a budget execution report — weekly for the investor, monthly for the financing bank. Capex spending vs. plan. Deviation history. Final construction cost forecast based on the current billing pace. A PDF or PowerPoint format ready for presentation without any manual effort.
Everyone handles their own scope.
The system builds the whole picture automatically. The right information to the right person at the right time — whether it’s an alert for the site manager when a budget category is exceeded, a cash flow report for the bank on the first day of the month, or a comparison of ten scenarios for the investor before making a refinancing decision.
None of these components replace one another. Together, they form a system that answers questions no off-the-shelf tool can even ask — because no off-the-shelf tool simultaneously understands the physics of an STR model, the logic of a construction budget, and the reporting requirements of a financing bank.
Who is it for
- Individual investors and family offices facing a decision on their first or next investment property — who want to compare business models before committing to specific capex.
- Developers and SPVs executing projects with external financing who require construction cost reporting in a format accepted by the bank.
- Owners of existing properties considering a change in their business model — e.g., converting an office building into student housing or moving from classic long-term rentals to STR — and wanting to see what that change means financially before deciding.
- Real estate funds analyzing multiple properties simultaneously who need scenario comparability across different projects.
Implementation
Origami Effect does not deliver financial model templates. It builds Artemis for a specific property, a specific market, and the exact business models the investor is considering. Echo is configured around the construction budget structure and the bank’s reporting requirements.
We start with a conversation about the investment — what you are considering, which models you want to compare, what the financing structure looks like, and what the bank requires in terms of reporting. Based on this, Origami Effect will design a system that answers your specific questions — not generic real estate market questions.
