For buying and selling purposes, values are usually based on market value — what the property could probably be sold for. Other types of value include insurance value, replacement value, and assessed value for property tax purposes.
Appraised value is not a constant number. Changes in market conditions can dramatically alter the valuation figures.
Valuation does not take into account special considerations, like the need to sell urgently.
Banks/Finance Institutions usually use either the valuation figure or the sale price, whichever is less, to determine the amount of the mortgage to offer.
