Only the land certificate, the house without real estate license depends on the nature of your land use right, whether it is homestead or collective land transfer, or urban residential land, and the compensation standard is different.
The compensation for house demolition built on urban land shall be based on the market price compensation or replacement compensation according to the property area. If there is no property right certificate, it can be reissued. If it belongs to the part of illegal construction, compensation will only be made within the scope of property confirmed by law. That is, you said that some people have real estate licenses and there are violations.
Without real estate license, the compensation is very low, and the maximum compensation can be the cost price of building materials. With property rights, you can replace houses of the same area according to the market price of houses, so you can try to apply for construction within the legal scope and reissue the property right certificate.
