Buying an Older Home

---

Older homes often offer character, craftsmanship, established locations, and unique architectural features. However, older properties may also contain ageing materials, deferred maintenance, hidden defects, or outdated building systems that buyers should understand before purchasing.

A professional building inspection can help identify visible issues and provide a better understanding of the property’s overall condition.

All buildings experience ageing and wear over time.

Common age-related issues may include:

• Roofing deterioration 
• Timber weathering 
• Cracking and settlement 
• Plumbing ageing 
• Electrical ageing 
• Moisture ingress 
• Timber decay 
• Ventilation issues 

Some ageing is expected and not always structurally significant.

Older homes may be more susceptible to:

• Roofing leaks 
• Subfloor dampness 
• Poor drainage 
• Inadequate ventilation 
• Historic water damage 

Signs of moisture issues may include:

• Musty odours 
• Staining 
• Timber deterioration 
• Elevated moisture readings 
• Mould growth 

Moisture problems should always be assessed carefully.

Many older homes show signs of settlement or movement over time.

Common observations may include:

• Minor wall cracking 
• Uneven floors 
• Door or window movement 
• Surface plaster cracking 

An experienced inspector can often help distinguish between:

• Typical age-related movement 
• More significant structural concerns 

Many older homes have undergone renovations over the years.

Inspectors commonly assess:

• Quality of workmanship 
• Moisture-risk areas 
• Structural alterations 
• Deck additions 
• Bathroom renovations 
• Extensions and alterations 

Older renovations may not always meet modern standards or expectations.

Some older homes may have:

• Limited insulation 
• Poor subfloor ventilation 
• Condensation issues 
• Inadequate airflow 

Ventilation and insulation improvements may be beneficial depending on the property.

Deferred maintenance is common in older properties.

Examples may include:

• Peeling paint 
• Corroded roofing 
• Timber decay 
• Failing sealants 
• Blocked gutters 
• General weathering 

Maintenance costs should always be considered when budgeting for an older home.

Older homes often require greater inspection judgement and practical experience.

Experienced inspectors are often better equipped to:

• Understand older construction methods 
• Recognise typical ageing patterns 
• Identify significant defects 
• Distinguish cosmetic issues from more serious concerns 
• Recommend further investigation where necessary 

A professional building inspection may help buyers:

• Better understand property condition 
• Identify visible defects 
• Understand maintenance requirements 
• Recognise moisture risks 
• Make more informed purchasing decisions 

Older homes can make excellent properties when buyers understand the condition and future maintenance obligations.
