Cross-Border Engine

Invest worldwide without being on site

Properties yielding 8–12 % in Florida, Ohio or Texas look opaque from a distance. Cadruno calculates US and international properties with the same hard numbers as the one around the corner – including every local cost that listings like to hide.

Local US costs, automatic

Property taxes, HOA fees, hazard and flood insurance, property management: Cadruno pulls local cost structures into the calculation automatically, before any yield is claimed.

Currency in view

USD to EUR/CHF conversion with a traceable rate: from the listing, otherwise from the stored table – the analysis names which. You see the cash flow in your currency, not the listing’s.

AI location & risk check

Straight from the listing text, the model spots location signals, condition risks and missing disclosures – and labels every derivation as such.

Questions that come before the first analysis

How does Cadruno calculate cash flow and renovation costs?

Cash flow is rent minus payment, non-recoverable costs and buffer – a deterministic calculation, not a guess. Renovation costs are computed across 20 trades with a regional factor, as an honest range instead of false precision.

Does the AI invent financial figures?

No. All financial calculations are strictly deterministic: cash flow, yield, payment and break-even rent come from fixed formulas, not from the language model. AI is only used where reading is required (e.g. listing text), and every number carries an origin label: listing, input, derivation, model or assumption.

Can I evaluate properties in the USA or internationally?

Yes. Cadruno analyzes listings from over 100 platforms worldwide, including US portals like Zillow and Realtor.com. Local costs such as property taxes, HOA fees, hazard and flood insurance and property management flow into the calculation automatically, converted into EUR or CHF.

Is it free to use?

Getting started is free: a one-minute account, no credit card, 30 analyses on the free tier. Paid tiers for heavier use will follow and will be shown transparently.

Is Cadruno investment or tax advice?

No. Cadruno is a decision aid: we calculate scenarios and show the origin of every number. For investment, tax or legal questions, professional advisors remain responsible.

Where do the numbers come from?

From five sources, always labelled: the listing, your input, derivation (deterministic calculation), model (AI) or assumption. No number without an origin.

Do I need an account?

Yes. Analyses are saved so you can compare properties and build a portfolio. Getting started begins with creating an account, then you run your first analysis.

Are you an alternative to ImmoScout & co.?

No. Portals show listings, that is where you find properties. Cadruno shows investments, this is where you decide whether one is worth it.

How reliable is the AI forecast?

Forecasts run exclusively through the model. If no model access is available, Cadruno shows a visible error instead of a substitute number. Better no number than a quiet guess.

Who is it for?

For private investors in existing property: from first purchase to a portfolio built alongside a day job. The app is currently built for desktop.
