When the house price is higher than the online signing price, banks often take the actual value of the house as the value of the collateral, so it is very important to evaluate the house. The evaluation results depend on many factors, including the geographical location of the house, the year of construction, the age of the house, the structure of the house and the decoration. Generally speaking, the actual value of the house will be higher than the online signing price, so in the house evaluation, the value of the house may be higher than the online signing price. However, the evaluation results should be objective, fair and accurate to ensure the interests of property buyers and banks and other lending institutions.
