The rental market in Seacliff is characterised by very high demand with a vacancy rate of 0.9%, which is well below the national average of approximately 2.5%. Vacancy is trending worsening, warranting careful monitoring.

Short-term rental data indicates a median nightly rate of $155 with an estimated occupancy of 64%. This translates to an estimated annual STR revenue of $36,208 before expenses. Long-term rental at $37,440/year may offer comparable or better risk-adjusted returns given lower management overhead.

If Seacliff maintains 3%+ annual growth and vacancy stays below 0.8%, median prices could reach $1,840,000 within 3 years with yields compressing slightly as capital values rise.

At current trajectory (-0.2% growth, 0.9% vacancy, 2.3% yield), Seacliff offers steady returns with moderate capital appreciation in line with broader market trends.

A market correction or interest rate shock could see prices in Seacliff pull back 10-15% from $1,600,000, with vacancy rising to 1.6% and rental yields softening as tenants gain leverage.
