I've got bad news for you, expect gas prices to spike back up to over $5/gal in the second half of November. Price always go down in an election year and spike up after. Gas being as expensive as it is right before an election is concerning.
IMO housing prices will likely go down in areas that didn't get hit hard in the 2008 crash (CA, NY). But other areas will see a small blip, and maybe be down 10-15%. But when prices are going up that much per year does it matter? The stock market has been massively over inflated due to all the free money from the Fed. Now the rich are fleeing and moving to buying properly to rent out. There's a reason Black Rock and the like are buying up houses everywhere.
