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

  • Laundry facilities, parking fees, pet rent
  • Storage rentals, vending machines
  • Late fees and application fees

    A 4-unit property averages $1,200/month rent per unit with $200/month other income and 8% vacancy.

    1. Gross monthly rent: 4 x $1,200 = $4,800
    2. Gross annual rent: $4,800 x 12 = $57,600
    3. Other annual income: $200 x 12 = $2,400
    4. Gross potential income: $57,600 + $2,400 = $60,000
    5. Vacancy loss: $60,000 x 8% = $4,800
    6. Effective annual income: $60,000 - $4,800 = $55,200
