Since the value of the property is an important factor in understanding the risk of the loan, determining the value is a key factor in mortgage lending. The value may be determined in various ways, but the most common are:
1. Actual or transaction value: this is usually taken to be the purchase price of the property. If the property is not being purchased at the time of borrowing, this information may not be available.
2. Appraised or surveyed value: in most jurisdictions, some form of appraisal of the value by a licensed professional is common. There is often a requirement for the lender to obtain an official appraisal.

3. Estimated value: lenders or other parties may use their own internal estimates, particularly in jurisdictions where no official appraisal procedure exists, but also in some other circumstances.
