The first time I met Travis was also to view a property in my neighbourhood. It was also a curiosity thing, and turned out to not be a good property. However that started some communication between Travis and myself, and ended up using him for my latest sale and purchase.
I can see the realtor possibly not wanting to be eager to show the property to somebody who (in my own words here), isn't serious enough about buying to even have a realtor yet. However a fellow realtor he'd be able to arrange a showing.
Also keep in mind that if you use your own realtor, the selling realtor does not need to come down to show the property. They just give the lock box code to your realtor, and that's it. So you are asking the selling realtor to spend his time to show you the place, when that is the buying realtor's job.
tl;dr - call Travis.
