Question:
Does the halacha of bar meitzra apply when the seller is a non-Jew allowing the Jewish neighbor to have first rights?
Second question does hilchos bar meitzra give a renter the right to purchase a property (That he’s renting) before an outsider?
Answer:
If one bought a property from a non Jew the neighbor cannot claim first rights.
There is a big dispute amonst the Rishonim if the halacha of bar meitzra apply to a renter. I suggest that the renter buy the property as quickly as possible, because if an outsider does, he can keep it.
