Need Advice on getting a property rented

[Janki Shah]

Just bought my first investment property back in July in Columbus, OH. One unit is rented out but it's been a challenge to get the other unit rented (Duplex). I'm an OOS investor and have a PM company handling everything. They said there's usually a two-week turnover but here we are over two months later and the unit is still empty. I'm not too happy with the PM company - they aren't on top of it, I have to keep following up with them about every little thing. The rent is the market rate (in fact $50 less than the Zillow estimate) but still no luck. It is an upstairs unit and I'm wondering if that's the reason it's not rented yet. I was thinking of installing a washer/dryer or offering half off the first month's rent. 

Any advice on what I can do?
