Thoughts on this deal?

[Joshua Palmer]

Hey Guys,

I'm relatively new here but have been listening to a lot of the podcasts, as well as reading the articles/forums. 

Here is a high-level breakdown of the 4-unit property I have been considering:
Asking Price: $149,900
Total Rent/Month: $2,135 = $25,620 for the year
Expenses (based on 2015): $12,371
Cap Rate: 7.80%
Cash ROI: 13.77%
NOI: $11,968
Annual Cash Flow: $4,720 (with a mortgage, tax, etc factored in)

Property Details:  
Four 2-bedroom, 1-bath apartments.
Clean and well maintained property.
Occupancy is approximately 98% annually (I figured 5% vacancy in my calculations above).
Tenants pay heat and electric.
Owner pays water and trash.
Newer roof installed in 2012. 

Your honest input would be greatly appreciated. Thank you in advance for your time and assistance.
