Example of Buying An Investment Property Calculation
Example Scenario:
- Property Price: $300,000
- Deposit: $60,000
- Mortgage: $240,000 at 4% over 25 years
- Monthly Rent: $1,800
- Monthly Expenses:
- Maintenance: $150
- Insurance: $80
- Letting Agent: $180
- Utilities: $60
- Void Period: 1 month per year
Estimated Result:
- Monthly Mortgage Payment: $1,267
- Total Monthly Expenses: $1,737
- Net Monthly Profit: $63
- Annual Net Income: $756
- ROI: 1.26% in the first year (excluding capital appreciation)

Factors Affecting Investment Property Profitability
1. Rental Income
Accurate market research ensures realistic rental income estimates, which is key to positive cash flow.
2. Purchase Price & Deposit
A lower purchase price or higher deposit reduces mortgage costs, increasing net income and ROI.
3. Mortgage Interest Rate
Lower interest rates reduce monthly payments and improve profitability.
4. Ongoing Expenses
Maintenance, insurance, management fees, taxes, and utilities significantly impact cash flow.
5. Void Periods
Unoccupied months reduce rental income. Planning for realistic vacancy rates is critical.
6. Property Location
Properties in high-demand areas may command higher rents but often come with higher purchase and management costs.
7. Taxation
Rental income tax, property taxes, and capital gains tax affect net ROI. Accurate planning is essential.
