Any tips on getting the highest valuation for a property you want to mortgage?
It helps to know that any surveyor's mindset when asked to value a property purchased a few months previously will be to value it at the purchase price paid, unless given compelling reasons not to.
When they arrive at the property they will be focused on the purchase price paid; your success in getting the highest valuation will be determined by how much you are able to shift their focus. Here is what I teach on my workshop on this subject.
Most importantly of all, you get your own survey done before you let a lender's surveyor anywhere near it. This is the biggest thing you can do to achieve that required shift of focus. A valuation report by a professional colleague (albeit from a different firm) will make it much harder for a lender's surveyor to value it below what your surveyor has valued it at. Your report will, of course, include comparables but, whereas your own are ignored, a RICS surveyor's will be believed.
All of the above should be presented to the lender's surveyor as a pack. Nothing will give you an absolute guarantee, but do all of the above and you are massively reducing the risk of a down valuation.
