Arya Sanghata Sutra: Print the sutra seven times and read it six times. You need to create extensive merits in order to buy and in order for them to sell.
Read the White Umbrella Deity prayer once and recite Lion-face Dakini prayer many more times.
Protector prayers—Recite the usual ones, particularly Kalarupa.
Perform the Incense puja three times. There is a particular one from the Nyingma tradition Riwo Sangcho. It involves paying karmic debts to sentient beings to eliminate obstacles and for success. It is a very short incense puja that is powerful.
Also, dedicate the merits for the Maitreya project to receive funding and be completed, and then for all the other projects to be completed with no obstacles. Dedicate all the offerings and services to monasteries such as Sera, Ganden, and Drepung, of the Lama Tsongkhapa tradition, and Tashi Lhunpo, the two tantric colleges, and other monasteries. Also, dedicate the merits for the FPMT to build monasteries and various holy objects in different parts of the world, which is the quickest way to purify sentient beings, allow them to collect extensive merits, and bring them to enlightenment. Dedicate the merits to offering social services in different parts of the world, to being able to help centers who have financial difficulties, and for other centers to be most beneficial to sentient beings, cause them to generate faith in Buddha, Dharma, and Sangha and actualize bodhicitta in their hearts, to particularly spread Lama Tsongkhapa’s teachings in their hearts, and to bring them to enlightenment as quickly as possible.
Then, particularly, ask for prayers for your wishes to succeed, for the benefactors’ and the international office benefactor’s wishes to succeed, and for all her business to be completed as quickly as possible, as well as for others who requested to have prayers for their success.
Finally, dedicate so that your center is able to acquire the property without any obstacle, financially, and also from the people's side—that they immediately and very happily respond.
