Effective Annual Income vs Average Monthly Rent Per Unit
公式
Projecting Rental Income
Rental income projection starts with gross potential income and adjusts for expected vacancy and collection losses.
Formula
Gross Potential Income = (Units x Avg Rent x 12) + Other Income
Effective Income = Gross Potential x (1 - Vacancy Rate)
Other Income Sources
计算示例
A 4-unit property averages $1,200/month rent per unit with $200/month other income and 8% vacancy.
- 01Gross monthly rent: 4 x $1,200 = $4,800
- 02Gross annual rent: $4,800 x 12 = $57,600
- 03Other annual income: $200 x 12 = $2,400
- 04Gross potential income: $57,600 + $2,400 = $60,000
- 05Vacancy loss: $60,000 x 8% = $4,800
- 06Effective annual income: $60,000 - $4,800 = $55,200
常见问题
What vacancy rate should I use?
Use your local market vacancy rate, typically 5-10% for residential. Higher for student housing or seasonal markets. Check local data from property management companies or census data for your area.
What counts as other income?
Laundry income, parking fees, pet rent, storage fees, vending, late fees, and any revenue beyond base rent. This can add 3-8% to gross income for well-managed properties.
Should I use current rents or market rents?
For valuation, use market rents to assess the property at its potential. For cash flow projections, use current actual rents and phase in increases to market rate over time.
