(CNBC) — The temperature may be frigid across much of the nation, yet home prices are sizzling and sellers are in the hot seat.

Sales prices jumped 7 percent annually in November, according to a new report from CoreLogic.

That is the third straight month at that pace, far higher than the price gains in the first half of 2017. Low supply and high demand are fueling the spurt and neither of those is expected to ease up anytime soon.
