I've thought about ferry flying (domestic) but I'm leaning against it ... and so are most brokers & insurance carriers.
It all comes down to familiarity with the individual aircraft and more specifically the systems on that aircraft.
In a strange airplane, if something goes bad, you just don't know where, what, when those specific systems will do, or not do.
There are countless stories of relatively higher time pilots getting into an airplane for the first time to take it someplace and they end up dead. And, it precisely those stories that have my local FBO requiring that if you want them to sell your aircraft you deliver it. They will not send a pilot to get it or deliver one they've sold.
Doesn't mean it can't be done, or done safely, but it's just an added risk for a relatively low return, IMHO.
