Is this quadplex negative CAP or just over priced?

[Orlando Goodon]

Is this $800k house simply over priced? I'm new to CAP calculations, but from what I understand I should have enough data here to calculate true value of property. How do I find out what this is really worth? Key details:

Price: $800k
Total gross income: $81k
Total gross expense(Tax is $1600/mo or $19k/yr!!, plus water, sanitation, insurance, internet, gas/electric[owner] ): $30k
Mortgage with 3.5% down: $42,804

Last sold potentially 10+ years ago (So could be cash flowing nicely on MUCH smaller mortgage)


So with 3.5% down, I see this house losing $1100/mo or a loss of $13,200. Please let me know what this house should be worth and share how you calculated it. Also, tell me what you think of this deal. Additional details:

Apartments all updated
Washer drier

1.5hr from NYC. Could approach 2 hrs on bad days, but I've done that going from Hackensack to NYC, although a bad day is typically 1.5hrs. Lots of full trains, train delays the tunnel traffic for Hackensack to NYC. However, on good days, it's an hour. The quadplex is 1.5hrs on good day...
