Found a property but the numbers don't seem right

[Michael Abate]

Hello fellow investors, I'm hoping that you can help clarify if I'm getting something wrong with a deal that came my way. I was planning on buying a property in NJ and after all the numbers, there is still a negative cash flow. But the property is still getting offers that are higher than mine. Some advice would be really helpful here and time is short here since they may accept the other offers before mine. The details are as follows:

• Current Price: $370,000
• My offer: $320,000
• Condition: House is in rent ready condition but I have added $5000 for touch ups here and there
• 2 Family House with each unit renting for about $1300
• Insurance/yr: $700
• Taxes: $11,500/yr
• Loan: FHA with 3.5% downpayment (30yrs)

Here is a link to the analysis that I did as well in case that helps, this is analyzed with both units rented out to know whether the investment is sound, even though one will be my primary residence:

Please let me know if I am missing something or if these other investors are offering too much. Thanks again and I look forward to hearing from you. 

Regards,
