Need advice on a whether to buy a duplex - Chandler Arizona

[Lisa Caracciolo]

I'm debating purchasing a duplex in Chandler, Arizona. I would be getting it from a wholesaler at $290k (ARV might be $330k) and it is made up of a 2/1, 625 sqft and a 1/1, 525 sq ft. It would be a value-add, I'd probably put in $20k so not a huge rehab. The part I'm worried about is that it backs up to the train tracks. Does anyone have any properties that back up to a train track and have you found them hard to rent out. I was thinking about looking at section 8 tenants for this one, it is in a C class neighborhood. This would be my first investment property and I'm having a hard time deciding whether or not to do it. Any advice is helpful :)
