I wouldn't count on it. The mortgage market is divided between conventional and jumbo loans[1]. Any bail outs will likely focus on conventional mortgages. The current administration seems to relish in screwing over blue states, and the house of representatives has a long list of negotiating priorities. They might be able to negotiate the SALT limits, but I don't see jumbo loan bail outs making the cut.
