Am I doing this right?

[Alfred Dublin]

Hey everyone,

I been practicing analyzing deals and running the numbers on multiple properties. 
Im wondering 

1. Am I calculating this right? Am I missing/needed something?

2. If these numbers are/were accurate how would you improve

Down Payment: $81,000

Loan amount: $244,000 Interest: 8%
Rent: $2500 

Expenses and mortgage: $2855

The house it’s a (Up/Down) duplex and (3/1) in each unit a combined 2760 sq ft. Old style house recently fully renovated new lvp floors, 5 year old roof,new paint, remodel not really a need, C+ neighborhood B- location downtown. Comes vacant. Rent can possible get a combined 200 more as owner was charging but being conservative on rent because of research and personal growing in living and paying rent around
