Lending Criteria - Last Updated 18th June 2018

Here you can find our lending criteria which is a comprehensive document on how we approach lending and what our underwriters will follow when personally assessing an application.

Lending Criteria

Valuation Fees

The mortgage valuation is to assess whether or not the property you want to buy provides enough security to the Society for your mortgage. To get this information we may ask our valuer to visit the property and produce a report. The cost of the valuation depends on the purchase price of the property.
