Multi-Unit Info on Realtor.com

[Stephanie Feld]

As I'm scrolling through the multi-family properties on realtor.com in my area, it occasionally breaks down information on the property:

• Gross Operating Income: $22800
• NOI: 19680
• Yearly Operating Income: 24000
• Other Income Description: None
• Yearly Operating Expense: $3120

• Maintenance: 50
• Assessed Imp Value: $39513
• Assessed Land Value: $10500
• 2 Bedroom Rent: $500
• Separate Meter: Electric
• Tenant Pays: Electric, Gas

How accurate is stuff like this? Does the buyer report the numbers? What are the chances these numbers are lies?
