What is really going on?

For me, the app works wonderfully. I am constantly finding homes that are amazing and that are good deals. However, every single one appears to be some out of town owner who wants me to pay upfront before I ever even set foot in the house. Smells like a scam. Sounds like a scam. Is it a scam?
