For jumbo-mortgage borrowers, new mortgage rules which go into effect on January 10, could limit choices. Other regulatory actions are also expected to kick in that could make credit access on the high end more expensive. Despite the changes more lenders are competing for their attention, which means that rates on jumbo mortgages could rise at a slower pace than other loans. Lenders may also require smaller down payments.
