Your property wealth. One clear view.

Rockheart Lane is a private portfolio app for property owners with holdings in more than one country. It tracks what you own, what it’s worth, what it earns, and what you owe — across Australia, Hong Kong, Germany, and the Netherlands — and turns it into tax-ready reporting when the year closes.

What it does

Built for owners who think in more than one currency.

Every property, one dashboard

Portfolio value, net worth, net cash flow, and what needs your attention — across every property you own, at a glance.

Multi-jurisdiction, multi-currency

Australia, Hong Kong, Germany, the Netherlands — each property in its own currency, rolled up into one household view.

Financing you can see coming

Loan balances, rates, and fixed-rate periods — including German Zinsbindung expiries — flagged before they matter.

Construction, tracked as it's drawn

Budget against spend for properties still being built, so a renovation's progress is never a guess.

Tax-ready reporting

A Tax Pack per property, per year, built for German depreciation (AfA) and the other reporting your accountant needs.

Real ownership, real contributions

Down payments, acquisition costs, and ownership splits tracked per owner — not averaged away.

Currency exposure, made visible

See how much of your wealth sits in each currency, and how a move in exchange rates shifts it.

Add a transaction in seconds

Quick entry for rent, expenses, and everything between — logged in moments, not spreadsheet rows.

Understand what your properties earn

Yield, cash-on-cash return, and market rates side by side.

Income and expenses over the trailing twelve months, gross yield and cash-on-cash return, and current mortgage rates in each of your jurisdictions — so a financing decision is made against real numbers, not a hunch.

Net worth is charted against the broader market over time, so growth reads in context rather than in isolation.

Financials page showing market mortgage rates by jurisdiction, an income and expenses bar chart, and a net worth versus market line chart. — Financials — returns, market rates, and trend, together.

Track equity across your portfolio

Every property and every loan, in one clean table.

Properties table listing country, status, monthly rent, purchase price, market value, loan balance, and equity for each property. — Properties — purchase price, market value, and equity, per property.

Loans page with total debt and payment figures, and a table of every loan including a fixed-rate period ending soon. — Loans — balances, rates, and fixed-rate periods flagged before they end.

Why owners keep it open.

One clear view instead of four spreadsheets, one per country.

Know what you own and what it's worth before your accountant asks.

See risk before it arrives — a loan reset, a currency swing, a lease ending.

Built to be trusted with two people's money — reconcilable, and ready to hand over.
