Two agents. Two verdicts. Both published unedited.

There's no honest valuation without a plan to get there - so we published both agents' full strategy, not just their number.

Agent's appraisal

A level parcel of land is quite rare in Mount Colah - and being so close to the park, the schools, the shops and the station all plays into it.

As-is, based off the matterport, in the current market, I'd put it in the vicinity of $1.5m to $1.6m. I recently sold a similar Mount Colah property, but in an inferior location - down Northland, quite steep, no public transport, a hike back to the station and that fetched $1.43m. Yours sits higher purely because of the level block and the location.

If you do some work - a kitchen update, a bathroom update, a little landscaping and painting - I could see it going up to around $1.7m. And with the right competition and timing, a premium result could be north of that.

Preparation to maximise

I'd keep the landscaping light - people will see how level the block is and fall in love with that parcel of land already. The value is in a kitchen update, a bathroom update, painting, and all the little pieces you find along the way.

Buyers today are time-poor and spending more time at home, so they're looking for properties they can turn the key and start living in straight away. Renovated homes are proving very attractive right now - that's where the premium is.

Sale method & marketing strategy

What's working in this market is giving people a deadline. I had three auctions in Mount Colah on the same Saturday just recently and sold every one - a 100% clearance that day.

A deadline actually helps buyers: it gives them time to work with, to get their parents, their solicitor and everyone across the documents and have a second look - rather than being pushed out or deprioritised the way they can be with an open-ended private treaty. So I'd lean toward an auction or deadline campaign - though if private treaty is your preference, we can absolutely work that way. It's a recommendation, not a rule.

On marketing, I wouldn't go over the top. A lot of heavy marketing is really about building the agent. For this property, the basics done well - photography, floor plan, copywriting, brochures, a signboard and the internet listings - are what matter.

Buyer profile

Two main groups. Families, mostly - the level block and the opportunity to add value down the track is very attractive to them. And the odd younger downsizer who wants to do a little work and start living straight away.

We're seeing a lot of people from nearby suburbs like Wahroonga and Pennant Hills wanting to downsize and get out of the two-storey home. Across our ten offices we've got a shared database, so any buyer looking for something like your home, we can put it in front of them directly.

Timing

It really comes down to avoiding the school holidays - it'll mostly be families looking, and I'd hate for a chunk of the market to be away when we want to extract every last dollar.

Stock in Mount Colah has been low for a while, so if you can get to market sooner rather than later, that's my recommendation. If you need to do the renovations first, plan around them - just keep clear of the school holidays.

Insights

I have a real passion for Mount Colah - 95% of my business comes from this one suburb, so I know the buyers, the location and the schools inside out. That hyper-local knowledge is what lets me find the right competition for a specific home.

Agent's appraisal

I've had a look at the property in great detail. Similar properties are selling between $1.35m and $1.45m as-is.

Slightly updated homes - putting maybe $50,000-$60,000 into it - are getting over $1.55m, possibly even to the $1.6m mark, for the same three-bedroom cottage on a nice flat block in Mount Colah.

Preparation to maximise

The strategy to maximise value is to completely declutter everything inside. I understand the tenants are currently vacating - that's the best option and once it's cleared out, a very deep clean: floors, walls, windows, sprucing it up as much as possible.

I'd go as far as changing the lighting and the blinds. It's not a full renovation - just getting it presenting to a point where the result is maximised.

Sale method & marketing strategy

The two ways to sell are auction or private treaty. For this property, in this market, I'd recommend a private treaty campaign.

The auction clearance rate is sitting around 50% at the moment - a few weeks ago it was closer to 35%. I'm getting a lot of buyer feedback that they're actually waiting for properties to pass in at auction, because they think they'll get a better buy afterwards. Days on market is crucial right now.

So I'd run a private treaty campaign with a single price guide - not a price range, which caps you - starting from around $1.4m to $1.5m, depending on what you're comfortable with. That gets people in the door, creates competition, and drives the price up as high as possible.

Buyer profile

Your target buyer is a first home buyer - someone looking to get their foot in the door. Anywhere around the $1.5m mark, there are lots of buyers; once you go above that, the pool thins out.

At the $1.5m mark you'll have a lot of first home buyers wanting to purchase and do work later. The property needs a few touch-ups, but buyers aren't afraid of that - the main thing for them is getting the location they want. The block is flat, a good size, and easy to renovate.

Timing

On timing - I always say the best time is when you're ready and when the property is ready, because there's a lot we can't control: interest rates, competition, recent sales.

Once the property's updated to a point you're happy to take to market, we're ready to go. My one piece of advice: if it's after the 1st of November, I'd wait until around February the following year.

Insights

If I were fortunate enough to represent the sale, my focus would be to create maximum buyer competition and control the campaign from start to finish.

Something we pride ourselves on is contacting everyone who missed out on a similar property - right across the patch, from Waitara to Berowra - qualified buyers we already know are looking for a home just like yours. And our whole team inspects the property on photo day, so they can each run a buyer investigation among their own contacts.

To sell in this market you really do need an experienced agent. I've worked through the GFC, the Royal Commission, and high interest rate rises, and still got clients premium results in a short amount of time.
