No, you're being given the chance of first refusal to purchase as is your right as a current tenant.

Answer

The sentence with "as is your right" is correct. It is idiomatic and totally correct. Similarly, as it is your right is also correct, it just has a slightly different meaning.

Answer

They mean the same. Without any change of meaning, you can break it into two sentences:

"You are being given the chance of refusal. That is your right."
