I checked which pujas need to be done for the obstacles you have with buying the property.

• You need to do or arrange for the following to be done twice: Gyag ngen Lhasang: Pleasing the devas/protectors, with an extensive incense puja for the devas and protectors.
• Write the Arya Sanghata Sutra five times. Others can also help to write it.
• Read the Arya Sanghata Sutra eight times.
