Why is Tangshan Century Longting House cheap?

The house in Tangshan Century Longting is cheap because of its poor quality. Most of the residents' walls are cracked in a large area, and the water pipes have been out of order for a long time. Every day, pits are dug in the community to repair the pipes, and the property developers do not admit the quality problems of the projects, so they pass the buck. Signed the house purchase contract in September, 20 10, and moved in in May, 2010/year. At that time, the real estate developer collected the deed tax in advance, but I didn't apply for the real estate license until 20 18, and the overcharged deed tax and the area difference that should be refunded were ignored. Residents are very dissatisfied.
