Question about outcalls

So I seen a ads that say the lady in question will only do outcalls to a house. no apartments, motel-hotel,etc. I can see safety issues with hotel/motels. What I was wondering is apartments. Is it the type of issues, or should I be worried about my house getting scouted for a break-in?
Gents and Ladies what are your thoughts.
Would say it could be a few things. 1) yes your house could be getting scouted, 2) it is a scam, 3) a combo of 1 & 2, 4) it could be le looking for Johns that use their own place for activities, or 5) it is on the up and up and by owning a home shows that you have money so there for you can afford the rate that they are wanting. However if this came off of bp then it is probably #3 or #4 on the list of things it could be and not a wise move to do.
