Using calculation results
Calculator results are intended to help with planning and comparison activities.
You may use the results to:
- Compare multiple investment opportunities.
- Review potential ownership costs.
- Estimate tax-related expenses.
- Understand the possible impact of a future property sale.
- Evaluate different financial assumptions.
The results should be reviewed together with your property information and other available analyses.
Understanding estimates
Calculator results are generated from the information you provide.
Because tax rates, regulations, and individual circumstances can vary, results should be treated as estimates rather than official figures.
More accurate inputs generally lead to more useful results.
If important financial decisions depend on the outcome of a calculation, consider verifying the figures with a qualified adviser.
Tax laws and rates can change over time. Recalculate and verify important figures whenever regulations or assumptions change.
Best practices
- Verify all values before running a calculation.
- Compare different scenarios when evaluating investments.
- Use the results together with your property analysis and cashflow projections.
- Review assumptions carefully before relying on results.
- Recalculate whenever important values change.
- Treat the calculations as estimates rather than official tax figures.
