Duplex looking to good to be true?!

[Chantai Ferguson]

Hey there! I could really use some help. I found a duplex, got preapproved, my realtor is super sweet but I'm realizing she's not extremely investor friendly. Anywho she believe the units could rent for 750 each it's in a great part or town, near a college, and the vacancy rate for that street is fairly low according to property managers.

Purchase price is 150k, tax 1500, insurance 1200. The tenants pay all utilities, trash, water etc. The owners are elderly and ready to get out of the landlord business.

Basically in my eyes it looks great on paper, BUT it's been on the MLS for 3 months. Things around it are still selling.

What could I be missing? What other things should I be looking at?

Thanks so much for any input!
