First deal, total newbie. Need advice if possible please.

[Theodore Ezzedine]

Good afternoon,

I am close to purchasing my first deal. I do not feel as if it is a good deal and I am a little hesitant. 

The property is located on Glenmore in Cincinnati. The deal is a 4plex at 260k. Currently there is 4 tenants, 2 under rent. I should get 700-750 per door. After the inspection, there was pretty much only issues with the sewer line. However, it was an improper pitch. I got a 2nd analysis, it does not need an immediate repair but 10-15 years I will which can be about 15-20k. I have an appraisal next week.
