I've always had a private in-call, it's my prefered way of doing business. I feel that it is safer/more secure as I can control the situation better than an out-call.
I have done out-calls, from time-to-time in the past, but as I am a fbsm provider, this just doesn't work without a proper massage table, so that is really the main reason I won't visit clients at their homes; though, in the past, I've had a few regulars who had tables at their homes, so in that case, I am more than happy to accommodate an out-call.
