Common income sources:
- Rental payments from tenants
- Parking fees
- Laundry income
- Storage unit rentals

Rental Investment Simulation Quiz
Question 1: Basic Net Profit Calculation
If a property generates $5,000 in monthly income and has $3,200 in monthly expenses, what is the monthly net profit?
Correct Answer: B) $1,800
Using the formula: Net Profit = Total Income - Total Expenses
Calculation: $5,000 - $3,200 = $1,800
The formula Net Profit = Total Income - Total Expenses provides a straightforward way to determine the net profitability of a rental investment each month.
Question 2: Impact of Expenses
If monthly income is $4,000 and monthly expenses increase from $2,500 to $3,000, how does net profit change?
Correct Answer: A) Decreases by $500
Original net profit: $4,000 - $2,500 = $1,500
New net profit: $4,000 - $3,000 = $1,000
Change: $1,500 - $1,000 = $500 decrease
Every dollar increase in expenses directly reduces net profit by one dollar, assuming income remains constant.
Question 3: Breakeven Analysis
What monthly income is needed to break even if expenses are $3,500 per month?
Correct Answer: B) $3,500
For breakeven: Net Profit = 0
So: Income - Expenses = 0
Therefore: Income = Expenses = $3,500
Always aim for positive net profit rather than just breaking even, as this provides a buffer for unexpected expenses.
Question 4: Net Profit Percentage
If monthly income is $5,000 and monthly net profit is $1,000, what percentage of income does the net profit represent?
Correct Answer: B) 20%
Net Profit Percentage = (Net Profit / Income) × 100
Calculation: ($1,000 / $5,000) × 100 = 0.2 × 100 = 20%
Net profit percentage helps compare the profitability of investments with different income levels.
Question 5: Negative Net Profit Scenario
If monthly income is $3,000 and monthly expenses are $3,500, what is the net profit and what does this indicate?
Correct Answer: B) $500 negative, losing money
Net Profit = $3,000 - $3,500 = -$500
A negative net profit means the investment costs more to operate than it generates in income.
Assuming that negative net profit is always bad. Some investors accept negative cash flow if they expect significant appreciation or tax benefits.
