Well you can call her phone #. If she asks for a deposit or money up front, just hang up and block the number. If she wants to meet at a private residence, that is a good sign but you still must be careful. Check the neighborhood out. If it is a hotel, it may be safe but then it may be trouble. I would google the phone number and see what comes up. Also depending on the location, it may be sketchy. Listen to your instincts and when in doubt, walk away. Error on the side of caution.
