Who We Act For

Two Kinds of Buyers. One Standard.

Local Home Buyers

You can already see most listings we can. Finding it was never the hard part. What you can’t see is what a home is actually worth, what’s wrong with it, and what the vendor will really take. Whether it’s your first home or your last one, you get an honest number on every property, due diligence that finds the problem while it’s still the seller’s problem, and someone negotiating for you while you get on with your life.

Relocating Home buyers

Buying into an area you don’t know is where the expensive mistakes happen. The wrong street, the wrong side of the highway, the commute nobody warned you about. We work both ends of the M1 and we’ll tell you which pockets hold their value, which ones look like a bargain for a reason, and what you should actually be paying. You’ll know the area before you’ve committed to living in it.

How It Works

A Precise Process, Start to Settlement

No guesswork and no hurry. Every stage is transparent, and every recommendation is backed by data, research and lived experience in the market.

Step One: Strategy

We define your brief together (objectives, budget, timeline, and the criteria that actually matter) so every property we present has already earned its place.

Step Two: Search & Due Diligence

We source off-market, pre-market and private opportunities, then investigate each one: comparable sales, growth data, building condition, planning overlays, downside risk, etc.

Step Three: Negotiate & Secure

We negotiate or bid on your behalf with a clear walk-away price. Our job is to secure the property on the best possible terms, not at any cost.

Step Four: Settle & Beyond

We coordinate contracts, building & pest inspections and settlement, and remain your advocate even after you become the property owner.

 Trustindex verifies that the original source of the review is Google. I couldn’t be happier with the service from Propx during the purchase of my South Penrith property. Their professionalism, market knowledge, and negotiation skills made the process seamless and stress-free. They took the time to understand my investment goals and secured a great property at a competitive price. Highly recommend Propx for anyone looking for a reliable and skilled buyers agent!

 Trustindex verifies that the original source of the review is Google. A huge shoutout to both Aria and Arian from PropX invest. Prior to engaging prop X I engaged many buyers agents as I was buying my first investment property interstate and wanted to make sure I was going about it the best way possible to ensure maximum success. After speaking to other agencies I struggled to find confidence within there processes which almost deterred me from even using a buyers agent until I was recommended prop X. After the first consult the team were clear with there approach, analysis and clearly had extensive knowledge about the property market which allowed me to gain enough confidence to proceed. From the initial consult to settlement of my first property I was kept well informed throughout every step of the way making my experience stress free and as seamless as it gets. I was more than happy with the property Prop X found for me and I look forward to watching it grow over the next few years so that I can engage the team again and keep building my property portfolio. I highly recommend prop X for anyone who needs assistance transacting with properties as I can assure you the Prop X team will take all the guess work out of the process and ensure you will have the best experience possible. A big shout and thank you again !!
Kind Regards Momin

 Trustindex verifies that the original source of the review is Google. Wow, absolutely amazed by Arian and his team here at PropX Invest. There is a certain stigma involving buyers agents and if they are really worth it, and I can say with full confidence they are absolutely worth it. Bought my first investment property, and as a busy person it took so much stress and effort off my hands. Did a valuation on the property just a week after it sold and we got $51,000 in equity… a great bargain and find. There was constant communication and quality information provided by Arian; from property reports, to suburb reports, to high quality data, it was expectational. No doubt in my mind that i will be re using them moving forward with ALL purchases and recommending friends and family to PropX Invest. Really glad I came across you guys on social media and took the leap! Will definitely be hearing from me in the future regarding referrals and more purchases from me :)

Thank you
Marcel

 Trustindex verifies that the original source of the review is Google. Aria, Arian, and Brad provided an exceptional buyer's agent service that completely transformed our property hunting experience. When we first introduced, we were losing hope in our property search, but they immediately turned things around with their professional and strategic approach.

What truly set them apart was how they took the time to understand our situation and presented us with clear, well-thought-out plans and potential outcomes. They didn't just show us properties; they carefully curated options and provided comprehensive materials for our analysis, helping us make informed decisions.

Their communication was outstanding - always available when we needed them and super friendly in every interaction. They patiently addressed all our questions and concerns throughout the journey, making what can be a stressful process much more manageable.

The team's expertise and dedication to finding the right property for us was evident in every step. They consistently went above and beyond, discussing each potential property in detail and ensuring we understood all aspects of our options.

I would highly recommend Aria, Arian, and Brad to anyone looking for a buyer's agent in Brisbane. They're truly professionals who care about their clients and deliver results. Thank you for helping us achieve our property goals!

 Trustindex verifies that the original source of the review is Google. The PropX team was recommended to me by a friend to assist me in purchasing an investment property. The guys have been amazing, and I couldn't be happier with the service received. As I am purchasing the property as part of my Super, there are a few extra requirements and the team have done all the hard work and taken all the stress away that usually comes along with finding the right investment. I highly recommend recommend PropX to anyone looking to find the right property.

Arian Namdar – Licence No. 20451121

Principal Buyer’s Agent
Six years in real estate, and involved in more than $100,000,000 of transactions. Arian acts only for buyers. He’ll tell you what a home is actually worth, negotiate or bid on your behalf, and say plainly when the right answer is to walk away. Now based on the Central Coast, he works both ends of the M1. He has even bought homes for his own family in this market, so Arian know’s what the Saturday-night conversation sounds like.

Aria Namdar

Head of Research
Aria spent his career on more than $8 billion of mortgage and asset-backed securities transactions. Work that came down to one thing: data driven strategies to mitigate risk and optimise client returns. He does the same here. Every property you consider is tested against the comparable sales, the risks and the numbers before you commit, so the price you pay is a conclusion rather than a guess.

Common Thoughts

Frequently Asked Questions

What does a buyer's agency actually do?

We act exclusively for you, the buyer, never the seller. That means defining your strategy, sourcing properties (most of them off-market), running due diligence, negotiating or bidding on your behalf, and managing everything through to settlement.

How do you access off-market properties?

Through long-standing relationships with selling agents and property owners across NSW and Victoria. Agents bring us opportunities before they launch publicly because they know we represent qualified, decision-ready buyers.

How long does the process take?

It varies with your brief and market conditions, but most clients secure a property 6 to 9 weeks of engagement. We’ll give you an honest read on your specific timeline in the first conversation, we don’t deal in hype or hurry.

Which areas do you cover?

We focus on the M1 corridor in New South Wales, primarily Sydney’s North Shore, Central Coast and Newcastle.

If your brief sits outside these markets, we’ll tell you plainly whether we’re the right fit.

Do you work with home buyers as well as investors?

Our focus is to support home buyers across the areas we cover.

However, we have helped many investors in these markets and are able to do so if needed.

The Right Home. The Right Number.

If we don’t save you more than our fee, our cost comes down by the difference.
