The Other 11 Costly Mistakes
These are easier to scan when grouped by where the loss actually happens: pricing, marketing, negotiation, legal, and timing.
Marketing
Marketing
The mistake
Using smartphone photos taken in poor lighting, showing cluttered rooms, or missing key features. 90% of buyers start their search online, and poor photos mean they never click on your listing.
What to do instead
Hire a professional real estate photographer ($300-$600). At minimum, use natural light, declutter every room, and take photos from corners to make spaces look larger. Include drone shots for properties with large blocks or views.
Marketing
The mistake
Listing a property without decluttering, cleaning, or minor repairs. Buyers struggle to see past mess and damage, leading to lower offers or no offers at all.
What to do instead
Create a room-by-room checklist: declutter, deep clean, fix minor repairs, touch up paint, improve curb appeal. Small investments ($500-$2,000) in presentation typically return 300-500% through higher sale prices.
Marketing
The mistake
Not listing on major property portals like realestate.com.au or using poor-quality online listings. 95% of Perth buyers start their search online - if they can't find you there, you don't exist.
What to do instead
List on realestate.com.au as a minimum. Upgrade to featured listings in competitive suburbs. Write compelling descriptions highlighting key features and ensure photos are professional quality.
Marketing
The mistake
Not knowing how many people view your listing, which photos they engage with, or why viewings aren't converting to offers. Without data, you can't improve your strategy.
What to do instead
Monitor portal statistics: views, saves, enquiries, and open home attendance. If views are low, improve photos or reduce price. If views are high but offers low, reassess presentation or pricing expectations.
Negotiation
Negotiation
The mistake
Accepting the first offer out of excitement or fear that no other offers will come, often leaving thousands on the table. First offers are frequently test offers to gauge your flexibility.
What to do instead
Evaluate each offer holistically: price, deposit amount, finance conditions, settlement date, and buyer circumstances. Counter with reasonable terms and allow time for multiple offers if your property is well-priced.
Negotiation
The mistake
Taking low offers personally, getting defensive with buyers, or making impulsive counter-offers based on frustration rather than strategy. Emotional decisions cost money.
What to do instead
Treat negotiations as a business transaction. Set your minimum acceptable price in advance. Take time to respond to offers rather than reacting immediately. Consider using an agent or solicitor as a buffer.
Negotiation
The mistake
Accepting offers from buyers without pre-approval or with unrealistic finance conditions. When their finance falls through weeks later, you've lost valuable marketing time and other potential buyers.
What to do instead
Request evidence of pre-approval before accepting offers. Negotiate shorter finance clauses (14-21 days rather than 28). Require reasonable deposit amounts (5-10%) to ensure buyer commitment.
Legal
Legal
The mistake
Not disclosing known defects hoping buyers won't notice. In WA, sellers must disclose material facts. Hiding defects can lead to legal action, cancelled sales, or financial penalties after settlement.
What to do instead
Complete a full disclosure statement honestly. Document all known issues including structural problems, flooding history, disputes, and unapproved works. Honesty protects you legally and builds buyer trust.
Legal
The mistake
Downloading generic contract templates online or trying to modify standard contracts without understanding WA property law. Missing clauses or incorrect terms can void the contract or expose you to liability.
What to do instead
Use the standard REIWA contract form. Engage a settlement agent or conveyancer ($1,200-$2,500) to review all terms. Have a solicitor review special conditions, particularly for complex sales.
Legal
The mistake
Only considering agent commission and forgetting settlement fees ($800+), government charges, penalty interest if settlement delays, and potential capital gains tax. These "hidden" costs can total $3,000-$5,000+.
What to do instead
Create a detailed selling cost spreadsheet including: settlement agent fees, mortgage discharge fees, marketing costs, potential CGT, and moving expenses. Get quotes from settlement agents before listing.
Timing
Timing
The mistake
Listing during Perth's slow seasons (December-January, school holidays) or rushing to list without proper preparation. Poor timing reduces buyer pool and sale prices.
What to do instead
Perth's strongest markets are typically February-May and September-November. Allow 2-4 weeks for proper preparation before listing. Monitor local auction clearance rates and days-on-market trends.
