just took first call inquiring about rental-sounding stupid?

[Tina S.]

I just posted my rental on Zillow (Cheyenne, Wyoming) and got a call from someone in Denver whose husband is being transferred here from Denver. She asked several questions about the property that I think I answered somewhat intelligently. She asked me what the process would be and I told her she would pay an application fee and do a credit/eviction check. Income would have to be 3 times the rent. In this case about $55,000/year. I told her I didn't have pictures of the kitchen and living area online yet because I was in the process of moving out and it's a mess (really?!) Also told her that if she was in town checking out houses to give me a call and I could show her the house. I was trying to remember what I had read here on BP while I was talking to her. But I feel like my mind was blank and I probably sounded like I didn't know what I was talking about. Which I probably didn't. I also don't have a lease prepared. I was going to buy one online. So, for those who are much more experienced-how do I handle phone calls in a simple, professional way? Thanks.
