Build ROI & Scenario Analysis

Compare Renovation & Fitout Scenarios, Calculate Returns

Compare different build and fitout scenarios side-by-side. For residential properties, compare renovation approaches. For commercial, evaluate fitout ROI including rent-free periods, make-good costs, and lease-term returns.

Key Highlights

Residential Scenario Comparison

Compare raise-and-build vs second storey addition vs basement conversion for the same property. Each scenario generates a full cost breakdown and end-value estimate.

Commercial Fitout ROI

Calculate the return on commercial fitout investment over the lease term. Factor in rent-free periods, make-good costs at lease end, and compare budget vs standard vs premium fitout grades.

Total Cost Accounting

Full cost accounting including purchase price, stamp duty, construction/fitout costs, holding costs, and estimated selling or lease disposal costs for a complete picture.

Budget Management

Generate detailed phased budgets with line items. Track budgeted vs actual costs, manage vendor quotes, and monitor variance from budget as the project progresses.

How It Works

1

Select Property & Scenario

Choose a property and select a build scenario (residential) or fitout type (commercial). Specify finish level and other preferences.

2

Cost Generation

The system generates detailed cost estimates using current market rates. Residential uses ABS PPI-adjusted rates; commercial uses published fitout guides.

3

End Value / Rental Analysis

Residential: comparable sales estimate the finished value. Commercial: rental premium analysis determines additional income from the fitout investment.

4

ROI Calculation

Total investment compared against estimated returns to calculate projected ROI, gross profit, payback period, and return per dollar invested.

Data Sources

Disclaimer: ROI projections are estimates based on current cost rates and comparable data. Actual returns depend on cost management, market conditions, quality of build, and factors beyond prediction. Consult qualified professionals before making investment decisions.
