Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE Students ( first_name VARCHAR, student_id VARCHAR )
TABLE: CREATE TABLE Student_Addresses ( student_id VARCHAR )

### Question ###
What are the id and first name of the student whose addresses have the highest average monthly rental?

### Accurate SQL ###

SELECT T1.student_id, T2.first_name FROM Student_Addresses AS T1 JOIN Students AS T2 ON T1.student_id = T2.student_id GROUP BY T1.student_id ORDER BY AVG(monthly_rental) DESC LIMIT 1
