Issue #20: The Renovate-and-Sell Deal Box

Written by Alex Zarate | Jul 30, 2026, 11:07:22 AM

I ran numerous deals through the numbers this past week. None made it into my deal box. Here is the framework that decides, and three of those deals worked through it.

Last week we ended on the gap: the distance between where you are and where you are going. This week was supposed to be about sizing your target. We will get there. But I spent the past week running numbers on renovation deals, one after another, and what happened is a better lesson than anything I had planned, so I am taking the detour.

Where equity comes from

If you want to accelerate your equity position right now, waiting is a weak plan. Equity only ever comes from four sources, and they split cleanly into two camps:

  • Market growth and debt paydown are the waiting sources. Growth you cannot control, and in the current market you cannot count on it either. Paydown works, but slowly, and it is capped by your cashflow.
  • Buying below value and adding value are the working sources: equity you capture on the day you purchase, and equity you manufacture through the renovation itself. That is where control lives.

So I have been doing exactly that: hunting for properties where a disciplined renovate-and-sell creates more value than it costs and such a deal can tick the "Buy below value" and/or "Add value" boxes. This week produced the finding that matters. The method is real, the margins in the data are real, and almost nothing on the market right now survives contact with the numbers.

The deal box: working backwards to one number

Every candidate goes through the same screen before I let myself like it. It produces a single number: the most I can pay. Everything is worked backwards from the exit:

Start with the sale price, renovated. What does this property sell for once the work is done? Not hoped for. Proven, by sold comparable sales, and at street level, not suburb level. This number carries the whole deal, and it is where most bad purchases are born.

Subtract the work. The full renovation budget plus a 10 to 15 percent contingency, because 1970s wiring and hidden water damage do not appear in listing photos.

Subtract the friction. Three parcels of cost that people forget until they arrive. Buying: stamp duty, legals, loan fees. Holding: loan interest for every month the work runs, plus rates and insurance, less any rent collected. Selling: agent commission, marketing, conveyancing. None of them build value. All of them are real.

Subtract the margin. The profit that makes the risk worth taking. I use around 15 percent of the sale price. This is not greed. It is the buffer that absorbs everything the first three numbers got slightly wrong.

What is left is the maximum you can offer. Here is the shape of it with clean illustrative numbers:

The deal box Illustrative
Sale price, renovated (street-proven) $700,000
minus the work (reno + contingency) $132,000
minus the friction (buy + hold + sell) $63,000
minus the margin (15% of sale) $105,000
= the most you can pay $400,000

On a $700,000 renovated exit, you can pay $400,000. Not $450,000 because the kitchen is charming. Not $480,000 because you have looked at forty listings and you are tired. The box does not care how good the photos are. That is its job. One technical note: stamp duty and loan interest both scale with the purchase price, so the real calculation solves for the number rather than guessing it. The logic, though, is exactly the table above.

If the asking price sits above the line, the deal does not work at any level of enthusiasm.

Three deals through the box

Now the week's work. I ran through numerous deals; I have picked three that show, between them, exactly how good-looking listings fail the screen. Each is fed through the same framework. I am keeping locations vague deliberately, because I am still negotiating in these markets.

Deal one: the gut job priced like a tidy home. A three-bedder in a Hunter town, asking mid five hundreds, marketed honestly as a full renovation project.

The box Deal one
Sale price, renovated $720,000 to $750,000
The work $130,000 to $145,000
The most I could pay roughly $410,000 to $450,000
Asking $540,000 to $560,000
Verdict about $100,000 above the line. Walk.

What made it look good: the suburb has a genuine spread of about $270,000 between original and renovated stock, which is exactly what this method feeds on. What killed it: a tidy, un-renovated house on the same street recently sold for the equivalent of roughly $650,000 to $680,000. The gap between this shell and a tidy home is $90,000 to $110,000, but closing that gap costs $130,000 to $145,000. The gap is smaller than the work. You would be paying near-tidy money for an unrentable shell.

Deal two: the one that flipped from yes to no. A three-bedder on a big level block in a regional centre, asking in the mid three hundreds, below what comparable original homes on big blocks sell for.

The box At suburb level At street level
Sale price, renovated $590,000 $460,000 to $480,000
The most I could pay $369,000 $243,000 to $279,000
Asking $355,000 $355,000
Verdict go, with $100k profit loses about $50,000. Walk.

What made it look good: everything. At suburb level, renovated homes on comparable blocks had sold near $590,000, the ask sat under my walk-away number, and the box showed roughly $100,000 of profit. I was a phone call away from offering. What killed it: the last check. A street-level pull of every sale on that exact street showed the best result in three years was $442,000. The $590,000 exit was borrowed from a stronger street two blocks away. Same suburb, different truth. Re-run the box at the street's real ceiling and the same deal loses about $50,000. One boring verification step refused a $50,000 mistake.

Deal three: the cottage with your profit already in the price. A period cottage in a heritage precinct, asking six seventy-five as a renovation project.

The box Deal three
Sale price, restored $730,000 to $777,000
The work $145,000 to $180,000
The most I could pay roughly $420,000
Asking $675,000
Verdict $255,000 above the line. Walk.

What made it look good: the pocket data is beautiful. Original cottages trade between $440,000 and $600,000, restored ones between $730,000 and $777,000. A real, confirmed spread of $250,000 to $300,000, on this exact street. What killed it: the ask. At $675,000 the vendor has priced the property at restored-money while selling a project. The uplift is real, and the vendor is proposing to keep all of it, in advance, on the buyer's behalf. As a flip it loses around $160,000.

What the week actually taught

Three walks is not the method failing. Three walks is the method working.

The spreads are real. In all three markets, the distance between original and renovated stock is $250,000 or more, confirmed by sold data. The machine that manufactures equity exists. What has changed is that vendors are pricing projects as if the renovation were already done, which means the uplift is being captured by the seller before the buyer lifts a paintbrush.

So the discipline is the least glamorous sentence I will write this month: manufacturing equity is mostly the work of saying no quickly. Compute the most you can pay before you inspect, before you meet the agent, before you imagine the finished product. Then an inflated ask is not a disappointment. It is just a fact, and you move to the next candidate.

And go one level closer to the asset. Deal two is the one to remember. The suburb-level story was seductive and wrong by $130,000. The street-level data was boring and right. Whatever level of evidence you are using to justify an exit price, drop one level down before you sign anything.

Where this connects to your numbers

Manufactured equity is not a hobby. It is a lever for closing a specific gap, which means it only makes sense if you know what your gap is. If you have not measured yours, the Property Portfolio Gap Analysis at pbco.com.au/property-portfolio-gap-analysis walks through it in about five minutes, free: position, target, and the distance between them. The lever comes after the measurement.

A note from me

I will be honest about how the week felt. Running deal after deal and killing every one of them feels like failure. It is the same feeling as standing at an auction watching someone else pay a number you refused to pay. But the second deal is the corrective. The process, followed to the last boring step, quietly refused a $50,000 loss that the suburb-level story would have signed off on. Nobody claps when discipline works. There is no moment. There is just a loss that never happens to you. I am still hunting, the target suburbs have not changed, and when a deal finally passes the box I will walk you through it, numbers and all. But I am not lowering the bar to make the market feel better.

See you next week.
