Hi Lidia,
While I am not a REVA, I did work in the Real Estate industry. From my experience and what I have seen, there can be both a broker and a manager for the real estate office. If you want to be sure you are sending your information to the person that is going to the decision maker, you may want to just give the offices a call and ask who is in charge (this is also a great way to establish a dialogue).
Where I worked, there was one broker, one manager and one owner! They each thought they were in charge

Unfortunately, sometimes the answer isn't going to be so cut and dry!
Those are just my thoughts and I am sure a REVA or two will jump in here and give you more information to go on.
Good luck!
