Does the owner have the right to cut off water and electricity if he defaults on the purchase price?

The property has no right to cut off water and electricity.

First of all, the purchase price has nothing to do with the property.

Secondly, no unit has the right to cut off water and electricity at will. Article 39 of the Regulation on the Supply and Use of Electric Power: If the electricity fee is not paid within the time limit in violation of the provisions of Article 27 of this Regulation, the power supply enterprise may, from the overdue date, impose a daily penalty of 0.3% to 65,438% of the total electricity fee, and the specific ratio shall be agreed by both parties in the power supply and use contract; If the electricity fee has not been paid for more than 30 days from the overdue date, the power supply enterprise may stop power supply in accordance with the procedures prescribed by the state. Article 35 of the Regulations on Urban Water Supply: In case of any of the following acts in violation of these regulations, the competent administrative department of urban water supply or its authorized unit shall order it to make corrections within a time limit and may impose a fine: (1) Failing to pay the water fee as required; If the circumstances are serious, the water supply can be stopped within a certain period of time with the approval of the people's government at or above the county level.

It can be seen that owing water and electricity fees can only be subject to administrative punishment, and water and electricity can not be cut off at will.

In real life, water and electricity cuts due to arrears can be seen everywhere. First, it is because the legal consciousness is not strong. Second, things that nobody cares too much about are definitely illegal. Citizens who suffer losses due to water and power cuts may apply for compensation through litigation.
