Any tax cut will favor the wealthy.
Prices will fluctuate and it doesn't really matter who won or lost the election. There are probably a few sectors (Oil) that will have a better outlook but that would be a few years later and won't be instant. Housing and groceries are probably going to increase and neither candidate has a good plan in reducing either.
Yeah mortgage rates are not going to drop all that much if at all. Even with the most recent rate cut today I don't expect mortgage rates to dip. We may see a small dip back down to sub 7% but it will then go back up again.
