Oh, and your question wasn't about this, but in your original post, I got the impression that you may have gone overboard on the finishes for the unit. Sadly, few renters will care for a property the way that you will. When choosing finishes, try to think about durability, cost effectiveness and whether the finish will pay for itself in extra rent or longer life. Don't get into the mindset of making it as nice as you would your own home. The counter tops, cabinets and flooring are ASSETS. They provide value in terms of making the space habitable / rent able.
I'm almost wondering if the house it "too nice" to be a rental. Have you considered selling it and buying something else? I would rather have a tri-plex with three little low-end units than one big beautiful SFH. I have never had any difficulty renting low-end apartments. Many working people just want something affordable and clean. There is always a big market for that.
