AI that doesn't just answer — it updates your plan.

Most tools give you a chat window. Stackhold's AI writes directly into your portfolio, income, and cashflow — so your plan moves as fast as your thinking.

Cockpit · Pro
I'm thinking of adding a $720k new-build in Hamilton, 6.2% IO for 5 years. Does it fit?

Yes — it fits. It lifts DTI to 6.3× (under 7× cap), portfolio LVR stays at 62%, and the new-build DTI exemption gives you headroom. Here's what I'll change:

  • + Add property: Hamilton new-build · $720,000 · IO 5y
  • Recalculate: DTI 5.8× → 6.3×, LVR 59% → 62%
  • ! Flag: $58k short on deposit — sell unit B or defer 8 months

Product workflow preview — structured actions are always shown for approval before anything changes.

Structured actions, not just chat

The AI speaks a structured action protocol that adds, updates or removes portfolio items, incomes, expenses, tasks and checklists. Every action is previewable — you approve before anything changes.

Portfolio-aware by default

Your full context — properties, base equity, income, lending rules, selling strategy, tenant and task data — is available to the AI. It doesn't ask you to re-explain yourself.

Guardrails, not guesses

The AI enforces your deposit, LVR, DTI and stress-test rules. If a suggestion breaches a limit, it flags it loud — with an alternative.

The first property platform with a built-in strategist

Not templates. Not rules of thumb. A custom-built engine that understands your position, the law, and the market — then builds your plan.

03
Stackhold market intelligence callouts highlighting suburb growth and yield data

Researches the market

04
Stackhold strategy plan showing property recommendations, numbers and next steps with dates Exact numbers Next step, dated

Builds your plan

You get specific properties, exact numbers, and numbered next steps with dates. Apply with one click — your whole portfolio updates.

Other tools show you what happened. The Strategist tells you what to do.

From spreadsheet chaos to one live plan

Stop juggling tabs. Run your portfolio from one screen.

Spreadsheets break the moment you add a property. Stackhold doesn't — every change to one number updates everything else, instantly and correctly.

Before

A spreadsheet, a notes app, and hope

A cluttered investor spreadsheet with broken formulas and stale data
  • Formulas break the moment you add a property.
  • Rents and rates go stale within weeks.
  • No idea what one bad deal does to the others.
After

One live plan that updates itself

Stackhold dashboard with annotated callouts pointing at live equity, headroom dials, and the next move card
  • Change one number, everything updates.
  • Lending rules baked in for NZ, AU, and US.
  • A real next move, with a date.

Investors using Stackhold tell us they save around six hours a month they used to spend wrangling spreadsheets, chasing rent changes, and rebuilding the same forecast.

What the cockpit does

Four jobs. One connected model.

Every screen knows every other screen. Change one number; the rest update — from tenants to cashflow to the 10-year forecast.

Built where you invest

Native rules for NZ, AU, US — editable for anywhere.

Not a US tool with other currencies bolted on. LVR, DTI, stress buffers, rent period (weekly vs monthly) and native terminology are built-in for New Zealand, Australia and the United States — and every rule is a default you can rewrite, so the same engine runs for investors in the UK, Canada, Singapore, Ireland, the UAE, or anywhere you own a door.

Investing somewhere else?

Every lending rule, stress buffer, tax convention and rent period in Stackhold is an editable default. Plug in your bank's LVR cap, your country's DTI or DSCR, your stress-test rate and your currency — the engine recalculates the whole portfolio the same way it would for NZ, AU or US. One cockpit, every jurisdiction.

Answers before you ask

Frequently asked

Is Stackhold financial advice?

No. Stackhold is a planning and modelling tool. The numbers and rules reflect typical lender behaviour and public regulatory guidance, but every deal depends on your broker, bank, accountant and lawyer. Always take licensed advice before acting.

Do I need to pay to start?

No. The Basic plan is free forever and covers the full app — portfolio, cashflow, multi-market rules, property management and personal finances — including AI: 5 Cockpit messages and 1 Stackhold Strategy run every month. Pro raises those AI quotas (500 messages and 30 Strategy runs / month) and adds priority support. You can upgrade any time inside the app.

How accurate are the lending rules?

We ship sensible defaults — NZ 65% investor LVR, AU 70%, US 43% payment-based DTI, plus stress-test buffers — and you can edit every rule per country. If your bank uses different thresholds, just change them and the whole engine recalculates.

Can I really manage tenants and documents in here?

Yes. Each property has its own admin space — tenancies (with start/end dates, bond, rent reviews), tasks and inspections, an expense log with optional receipts, a document vault for contracts and certificates, and key-date reminders. Stackhold isn't a tenancy-platform replacement (we don't collect rent), but for self-managers it removes the spreadsheet-and-sticky-note layer entirely.

Does it use my personal finances too?

Yes. You add your income sources, monthly and annual expenses, and your liquid cash. The engine uses these to compute real serviceability, deposit-readiness and DTI — so when it tells you the next-buy date, that number reflects your actual cashflow, not just the rentals.
