4. How do I know what my item trade market value is?

If neccessary your item will be independantley valued, the trade market value will then be determined by what the trade would pay for the item.
For example if you have a Grand Piano which is valued by an independent valuer, who values it at £4000, this valuation will be checked against what the market would pay at the time, this is therefore classed as Trade Market Value. Loan Purchase will then purchase your item for 30-50% of the trade market value.
