Key Real Estate Metrics

Property Value

The property value is the estimated worth of the real estate. This value can be affected by various factors including location, property condition, and market trends.

Return on Investment (ROI)

ROI measures the profitability of an investment. For real estate, it's calculated as:

Where net profit is the difference between rental income and all expenses, and total investment includes purchase price, closing costs, and any renovations.

Mortgage Payment

Mortgage payments are calculated using the standard mortgage formula:

Where M is the monthly payment, P is the principal loan amount, i is the monthly interest rate, and n is the number of payments.

Cash Flow

Cash flow is the net amount of cash generated by a property after all expenses. It's calculated as:

Positive cash flow indicates a profitable investment.

Worked Examples

Example 1: First-Time Home Buyer

Let's calculate the monthly mortgage payment for a first-time buyer purchasing a $300,000 home with a 20% down payment and a 30-year fixed-rate mortgage at 4%.

1. Down payment: $300,000 × 20% = $60,000
2. Loan amount: $300,000 - $60,000 = $240,000
3. Monthly interest rate: 4% ÷ 12 = 0.333%
4. Number of payments: 30 years × 12 = 360
5. Monthly payment: $240,000 [0.00333(1.00333)^360] / [(1.00333)^360 - 1] ≈ $1,245

Total interest paid over 30 years: $1,245 × 360 - $240,000 ≈ $154,620

Example 2: Investment Property

For an investment property purchased for $250,000 with $50,000 in closing costs and $2,000/month in expenses, and generating $1,800/month in rental income:

1. Total investment: $250,000 + $50,000 = $300,000
2. Annual net profit: ($1,800 - $2,000) × 12 = -$2,400
3. Annual ROI: (-$2,400 / $300,000) × 100 = -0.8%

This negative ROI suggests the property may not be profitable without additional income sources or appreciation.
