Issues renting my 3bdrm in converted house. Urbandale, IA

[Rachel Payton]

I own a 5-plex in Urbandale, IA. The largest of the 5 units is a 3-bedroom, which is the vacant one. The other 4 are 1 bedrooms. The 3bedrm is super nice, and over 1600 sq/ft. Laundry in-unit, pet friendly... all the things you could want in an apartment. I'm having some real problems finding people who are interested because the unit is in a converted house. So the pictures of the building look like a single family home. I've had several people contact me thinking it's a house (even though the ad clearly states apartment) The rent I'm asking for is comparable from what I'm seeing in CL. But it seems like there's a LOT of competition. There are TONS of ads for the same apartment from large complexes. I'm not using a management company right now. I've attached my CL link. (I realize many of the photos aren't great, i'm having professionals taken tomorrow) Any suggestions on how I can better market this place, or if I'm way off base on my pricing, would be appreciated.
