When you've had a remortgage valuation in the past, have you provided the valuer with any additional information supporting the valuation? For example, details of comparable properties recently sold, or extra info about the property that's not immediately obvious (such as share of freehold if it's a flat, etc), or details of improvements you've made since purchase/last valuation, or anything like that?
Or do you think giving info like that might annoy the valuer - seem like you're being pushy or trying to do their job for them?
