Right now, the 10-year treasury bond is jumping up. With the rise in the 10-year bump, consumers will most likely see another rise in mortgage rates. That is because most loans are sold on the secondary market and they share the same demographic as the investors who buy bonds. So, when one goes up, lenders have to increase interest rates so they can sell the loan to investors who are willing to take on a bit more risk. Interest rates on a 30-year fixed rate mortgage are around 4.625%, which is still relatively low on an historic scale.
