He is not a portfolio investor. He owns one house, in an outer-eastern suburb, bought in 2015 with his wife when their second child was on the way and the plan was to move into it one day. That plan quietly became a different plan. They stayed where they were, the house went to a tenant, and for eleven years he has managed it himself — advertised it himself, met the applicants himself, chosen them himself.

In eleven years he has had four tenants, no tribunal hearings, no bond disputes and, by his own account, one late rent payment which was fixed with a phone call. He is, on any reasonable measure, a careful landlord.

Last month his tenant of three years gave notice. He went to re-advertise, sat down to update the application form he has used since 2015 — the one he built himself out of two agency forms he'd been given years ago — and found that the rules had moved underneath him.

His question, which arrives in our inbox in one form or another almost every week now, was this: "How much of what I've always done is now illegal, and how would I even know?"

What actually changed

The short answer is that a rental application is no longer a document a landlord gets to design.

There is now a prescribed form. Rental providers and their agents must use it. That is the change that catches people out, because it inverts the logic everyone was operating under. The old assumption was that you could ask anything that wasn't specifically banned. The new position is closer to the opposite: the form sets out what may be asked, and a question that isn't on it isn't permitted.

Inside that form, the boundaries are unusually specific. A provider can ask for personal details — name, date of birth, current address, phone, email. Employment details, including net weekly income, current or most recent employer, and if the applicant isn't working, when their last job ended. Rental or residential history, including previous providers' contact details. Personal referees. The lease term and move-in date they'd like.

Financial evidence is capped: no more than two documents from a defined list — pay slips, a bank statement, or Centrelink statements. Identity is capped the same way: no more than two documents from a defined list of about a dozen. Not "whatever you feel you need to be comfortable". Two, and two.

And there is a short list of things that can no longer be asked at all. Whether the applicant has ever taken legal action or had a dispute with a rental provider. Their bond history, including whether a claim was ever made against their bond. A bank statement showing daily transactions — a statement can be requested, but the applicant is entitled to redact the transactions they consider private. Where a provider asks about a protected attribute under equal opportunity law, they must put in writing why they need it.

For an owner like him, this is the uncomfortable part. Three of those four were on his form. Not out of malice — out of exactly the instinct you would expect from someone protecting an asset. Have you ever been in a dispute with a landlord? Has a claim ever been made on your bond? He thought he was being diligent. Those are now questions he cannot ask.

Nor is it only the form. Properties must meet the minimum standards at the time they are advertised, not merely by the time someone moves in — and advertising one that doesn't is an offence in itself. Advertising must state a fixed price, not a range, and offers above the advertised rent cannot be invited or accepted, which matters because plenty of self-managing owners have historically thought that accepting an unsolicited higher offer was fair game. It isn't. Rent increases now require 90 days' notice. Fixed-term agreements that end now roll automatically into periodic ones unless there is agreement otherwise or a valid reason to issue notice. Smoke alarms need an annual check. And from October, a bond claim has to be flagged in advance and supported by evidence, while gas and electrical safety checks move to a mandatory two-year cycle.

Then energy efficiency standards begin phasing in from March 2027 — heating, cooling, hot water, showerheads, ceiling insulation, draughtproofing.

So the honest answer to his question is: more than he thought, and the pace hasn't finished.

The part he got wrong, and the part he got right

He got the compliance question right. It is a real question, it has a real answer, and the answer is not complicated — use the prescribed form, don't ask what isn't on it, get the property assessed against the minimum standards before it goes to market, and diarise the dates that are still coming. An hour with the current rules, or a property manager who is across them, closes almost the whole gap. This is administration. It is not existential.

What he got wrong is more expensive, and almost everybody makes the same mistake.

He assumed that because the rules are the loudest thing happening to him, they are the most important thing happening to him.

They aren't. They're the most uniform thing happening to him. Every rental provider in the state has the same prescribed form, the same two-document cap, the same 90 days, the same phase-in dates. A rule that applies identically to every competing property cannot explain why one of those properties will outperform another — and it certainly cannot explain the gap between two houses in the same suburb, on the same council rates notice, with the same regulations printed over the top of them.

Where the money actually moves

Here is the number that should have been keeping him awake instead.

When we measure rental performance at street level rather than suburb level — using achieved rents rather than advertised ones, actual vacancy duration rather than a headline vacancy rate, and real days-on-market rather than an agent's estimate — the spread in effective yield between the best and worst streets inside a single suburb routinely runs to 20–30%. Same postcode. Same median. Same school catchment, often the same train station. Same rental laws, to the letter.

That gap is not a rounding error, and it is not a matter of taste. It is built out of things that are measurable and stubbornly local: how deep the tenant pool actually is on that run of houses, how long a property genuinely sits before it lets, how much competing stock comes onto the same street each spring, whether the buyers who eventually take the property off your hands are owner-occupiers or other investors, and what they'll pay.

Now compare the two problems side by side, because this is the whole argument.

The compliance problem costs him an afternoon, once, and is then solved permanently. It is knowable, published, free to read, and identical for his competitors. The selection problem — which street, which side of it, which tenant pool — costs him nothing to think about and everything to get wrong, compounds silently every year he holds, is different for every property, and is published nowhere at all.

He has spent three weeks on the first one. He has spent, on his own admission, about a weekend in 2015 on the second.

That is not a criticism of him. It's the default. Regulation arrives with a date, a form and a headline, so it demands attention. Street-level performance arrives as a slightly disappointing rent review eleven years in a row, so it doesn't. One of them announces itself. The other one just quietly takes the money. This is the same asymmetry we've written about when an owner raised the rent $100 a week and was called a parasite by his own family — the argument looked like it was about ethics, and it turned out to be about data.

It is also why the same reform package lands so differently on two owners. A tighter regime is a genuine cost, but it is a cost applied to an asset — and a well-selected asset absorbs it out of the margin it already had, while a marginal one doesn't have the margin to absorb anything. Rising obligations don't fall evenly. They fall hardest on properties that were only ever working because nothing went wrong, which is precisely what we saw when an owner ended a tenancy to sell, failed to sell, and then couldn't legally re-let, and again when a $210,000 renovation came back valued at almost exactly what the house was worth before. The constraint was never the thing people were arguing about.

What we told him to do

Fix the form this week. Use the prescribed one. Delete the two questions about disputes and bond history — and understand that losing them costs him far less than he fears, because the information they were meant to surface is better obtained from rental history and referees, which he is still entitled to ask for, and from tenancy databases, which he may still use provided he tells the applicant which ones. Get the property assessed against the minimum standards before it is advertised, not after. Put the coming dates in a calendar.

Then, once that's done and it stays done, go and do the thing he has never done: find out how his street actually performs. Not his suburb. His street. What genuinely gets achieved there, how long properties sit, who the buyers are, and how any of that compares to the run of houses four hundred metres away that shares his median and shares nothing else.

Because the rules are going to keep changing, and every one of those changes will be published, dated and identical for everyone. The thing that is different about his property — the thing that has been quietly setting his return for eleven years — has never appeared in a headline, has never had a compliance deadline attached to it, and is the only part of this he can still do something about.

The reform noise makes property feel like a harder asset to own than it was. In truth it makes it a harder asset to own carelessly, which is a different sentence entirely. The owners who come out of this period ahead won't be the ones who read the fastest. They'll be the ones who worked out, before they bought, which four hundred metres they were standing on.

He researched the rules. He never researched the street. Almost everyone does it in that order.
