The Story Behind CST Properties - Commercial Real Estate Agent Sydney
Building on a 60-Year Family Legacy
Con Tastzidis is a Sydney commercial real estate agent with over 40 years of integrated property and business expertise.
His career trajectory is unique: beginning with hotel operations—food and beverage cost control and purchasing management at the Sydney Sheraton, opening team member for the five-star InterContinental Sydney, and six hotel openings for Resort Hotels Australia—before expanding into full-spectrum commercial real estate across retail, industrial, office, hospitality, and service industries.
This dual background, combined with lecturing credentials at the University of Technology Sydney and International College of Management, Manly, gives Con a perspective few commercial agents possess. When he founded CST Properties in 2001, Con was continuing a 60-year family legacy that began when his uncle Chris Tastzidis established Cosmos Real Estate in 1964.
Today, CST Properties has evolved into a comprehensive business and property divestment agency. We specialise in helping mid-market owners prepare, position, and sell high-value assets. Unlike traditional brokers who only list properties, we use a proprietary preparation methodology to maximise asset value and ensure secure transitions for our clients.

Specialised Expertise: Hospitality Properties
While CST Properties handles all commercial property types—retail, industrial, office, and service industries—Con brings unique specialised knowledge to hospitality transactions that few commercial agents possess.
Deep Industry Background
Before entering commercial real estate, Con gained operational experience that informs his hospitality property work today:
International Brand Experience:
- Opening team member, five-star InterContinental Sydney
- Operational management, five-star Sheraton International
- Six hotel openings for Resort Hotels Australia
- Senior management roles in hotel and catering operations
Academic Credentials:
- Lecturer in hotel and catering management at University of Technology Sydney
- Lecturer at International College of Management, Manly
- Taught operational and financial fundamentals of hospitality businesses
Why This Background Matters
Working with international brands like InterContinental and Sheraton means understanding:
Operational Excellence Standards:
- Brand compliance requirements that affect property value
- Service delivery systems sophisticated buyers evaluate
- Quality benchmarks that command premium pricing
- Operational metrics international investors scrutinise
Property Requirements:
- Physical specifications for international brand standards
- Layout optimisation for operational efficiency
- Amenity requirements for different hotel categories
- Renovation considerations that maintain or increase value
Financial Performance:
- Revenue management strategies that maximise income
- Cost control measures that improve EBITDA
- Capital expenditure planning and ROI analysis
- Performance metrics beyond basic NOI calculations
The Practical Advantage
This background creates tangible benefits for hospitality property clients:
For Hotel/Motel Sellers:
- Identify operational improvements that increase sale value before listing
- Position properties through an operator's lens, not just asset perspective
- Speak the language of sophisticated hospitality investors and brand operators
- Understand RevPAR, ADR, occupancy optimisation, and other metrics buyers evaluate
- Recognise which improvements deliver ROI and which don't
For Restaurant/F&B Sellers:
- Evaluate kitchen layout and equipment efficiency
- Assess operational flow and improvement potential
- Present business performance metrics that resonate with experienced buyers
- Navigate complex business + property combined sales
- Identify value drivers beyond location and fit-out
For Hospitality Buyers:
- Realistic assessment of operational potential and challenges
- Market positioning advice based on competitor understanding
- Due diligence guidance beyond standard property inspection
- Connection to operational expertise when needed
- Brand feasibility assessment for properties with franchise potential
Not Limited to Hospitality
This specialised knowledge enhances Con's hospitality work without limiting his broader commercial practice. CST Properties actively handles:
- Retail properties: Shopping centres, standalone retail, investment properties
- Industrial properties: Warehouses, manufacturing facilities, logistics centres
- Office buildings: CBD and suburban commercial offices
- Service industry businesses: Commercial services across sectors
- Development sites: All commercial categories and mixed-use opportunities
The hospitality expertise is an additional strength, not an exclusive focus. Con's 40+ years span the full spectrum of commercial property transactions, with hospitality representing one area where he brings uncommon depth of knowledge.
The Competitive Advantage
Most commercial agents learn about hospitality properties by selling them. Con learned by operating them—at the highest international standards.
This inside perspective on what makes hospitality businesses succeed (or fail) informs every hospitality transaction he handles, while his broader commercial experience ensures sophisticated representation across all property types.

The CST Properties Philosophy
Why We Recommend Waiting Sometimes
Here's something most won't tell you: we often recommend clients delay selling.
This might seem counterintuitive—we could earn commissions faster by listing immediately. But we'd rather give you honest advice that maximises your outcome than rush you to market and watch you leave money on the table.
Recent example:
A client wanted to sell immediately. We identified three operational improvements that would take 6 months but add $400,000+ to sale price. They waited. The improvements paid off. They thanked us for the honest advice.
Our priorities:
Your optimal outcome matters more than our commission timeline.
Long-Term Relationships Over Transaction Volume
We focus on outcomes that create referrals and lasting relationships, not on churning through deals.
This means:
- Fewer clients served deeply vs. many served superficially
- Time invested in preparation, not just marketing
- Strategic advice even when it delays our income
- Relationships that span decades, not just transactions
Your success builds our reputation.
That's why we care so much about getting it right.
Our Integrated Ecosystem: Navigating Your Entire Journey
The most common scenario we see is an owner who holds both a business and the property it operates from. Most agencies handle these as fragmented, separate sales. We know that lease structures, business performance, and property value are deeply connected.
To best serve our clients across every facet of their divestment journey, we operate three specialised divisions under one roof:
CST Properties (Core Brokerage): Our central hub for end-to-end commercial real estate sales, business brokerage, and commercial leasing. We manage the complex integrations when you are selling both a business and its premises.
Legacy Architects: Our dedicated transition and exit-planning division. We help owners assess their divestment readiness, structure succession plans, and optimise their assets long before they go to market.
Australian Leisure Property: Our highly specialised marketing arm dedicated exclusively to the tourism, hospitality, and leisure sectors, connecting sellers with targeted global investors.
Experience Across Market Cycles
What 40+ Years Really Means
Con has successfully navigated:
1980s: High inflation, market volatility, technology revolution
1987: Stock market crash and property market impacts
1990s: Recession, recovery, Asian financial crisis
2000s: Dot-com bubble, steady growth period
2008: Global financial crisis, credit crunch
2010s: Low interest rate environment, strong growth
2020s: COVID-19 disruption, rapid recovery, new challenges
Each cycle taught valuable lessons:
- What actually works vs. what sounds good
- How to protect value during downturns
- Where opportunity hides during crises
- What buyers really care about
- Which preparation work delivers real ROI
You benefit from all these lessons.
