Brokers felt most confident about continued funding from lenders at all loan-to-value (LTV) tiers, followed by demand for remortgaging.
Potential house price growth and homeowners having sufficient equity in their homes to move emerged were also among the issues brokers were confident about.
Graham Felstead, head of NatWest Intermediary Solutions, said: “The continued sunny outlook for the residential mortgage market has certainly been underlined by our latest survey with four out of the six components recording their highest ever broker confidence scores.
“The fluidity of the market is, to a great degree, dependent on both the anticipation that house prices will rise and that homeowners have sufficient equity in their current properties. It’s telling that confidence in both of these measures has risen, indicating that brokers believe homeowners have the capability to move and, consequently, creating a demand for mortgages. The only real concern that brokers have is over the supply of suitable properties for people to buy which could inhibit some market growth.
“2016 is set to be another good year for the mortgage market and we will continue to place heavy emphasis on growing our broker relationships, maintaining an attractive and wide-ranging set of mortgage products and providing a first class service.”
