December saw a record $14.1 billion in mortgage lending, driven by a massive refinancing rush.

Bank switching accounted for $5.8 billion of this total, more than double the previous high. The main driver was large cash-back incentives, which banks ramped up to 1.5% of the loan value. The data suggests it was mainly financially 'safe' borrowers taking advantage of the situation.

While the biggest cash-back offers have since been reduced, switching may still be worthwhile for some homeowners.
