I checked re the property next door. The people will not be happy if you approach them. However, if you do seven malas of each of the following mantras before you talk to them and take a nice gift (your friend can do a mo to check which gift), they will be happy and consider your offer.

The "mantra to love you" is the one called "The Exalted Zung Extremely Pacifying Anger."

The mantra where they treat you like a son – the "Mantra Accomplishing All Actions" – is not to be given out or used publicly, it is a secret practice.

Your motivation should be of real charity and bodhicitta, wanting to make sentient beings happy. This becomes one of the means to gather disciples. You need to dedicate well that they slowly become interested in the Dharma and can achieve the path to enlightenment.

I am sending HUGE LOVE to both of you.
