i have a “friend of a friend” that’s been flipping full time for the past 20 years. From talking to him, he’s never had a slow down because most “pro” flippers focus on the low end of the market, where they have enough cash to invest. Margins are low, but they make up for it in volume. Also, higher end homes are real risky for them because the people looking in that range tend to be pickier and more demanding.
