The change in criteria is available on single residential properties in England, Scotland or Wales.
The lender allows AVMs to be used against more than one property per loan and can be applied to loans up to £1.25m in London and £750,000 elsewhere.
The change is part of an extension and upsizing of an existing £200m warehouse facility, provided by a long-term relationship bank of Glenhawk.
This facility sits alongside Glenhawk’s other institutional warehouse and forward flow partnerships.
The lender said this has been increased due to strong demand for its bridging products.
