What a personal AI agent can work out about an Australian home loan, what it can’t, and how to give it the right numbers.
No — but it can do most of the work first. An agent can tell you what you could borrow, what a lower rate would save, whether refinancing covers its own costs and what your lender’s discharge process is. It can’t apply. In Australia a lender assesses the credit and a licensed broker submits it.

Any assistant that speaks MCP
Ask any assistant what you could borrow and it will answer. The answer will be plausible and it will usually be wrong, because Australian lending has rules a general model doesn’t carry. Lenders test your repayments about three percentage points above the rate you’d actually pay. Stamp duty runs on eight separate state scales that move at budget time. Usable equity is not value minus balance — it’s 80% of the value minus the balance, which is often less than half as much.
Connecting arthr replaces the guess with the sum. Every answer comes back with a link to the calculator that produced it, so you can check the figure rather than take the model’s word for it.
An agent can
Work out borrowing power, repayments, refinance savings, break-even, usable equity and stamp duty. Look up your lender’s discharge form and how long they say it takes. Re-run all of it whenever your numbers change.
An agent can’t
Apply for a loan, be the credit assessor, or tell you the rate a lender would give you. Those need a licensed broker and a lender, and no amount of automation removes them.
No. A home loan is credit, and in Australia a lender has to assess it against their own rules while a licensed broker submits it. An agent can do everything up to that point — work out what you could borrow, compare rates, check whether a refinance pays for itself, find your lender's discharge form — but it can't be the applicant or the broker.
For the research, yes. For the loan, no. An agent will happily produce a confident number, but it can't submit an application, negotiate with a lender's credit team, or fix a file that gets declined. Those are the parts that decide whether you get the loan, and they're regulated for that reason.
It can compare the maths, which is most of the question. Connected to arthr it will run repayments, borrowing power, refinance savings, break-even and stamp duty on real Australian rules rather than guessing. What it can't do is tell you the rate a particular lender would give you — that depends on your situation and comes from a broker.
Not yet, not through arthr. A persistent agent can re-run the numbers whenever you ask, and if you tell it your balance and rate it will tell you what a better rate would save and how long the switch takes to pay for itself. It can't watch the market for you, because arthr's tools don't quote live rates — you supply the rate to compare against.
Yes. No account, no API key, nothing to authorise. The tools take numbers, do the sum and send the answer back, and we don't store what you asked.
An estimate tells you roughly where you stand. A broker tells you what you can actually get, and then goes and gets it.
