gmb - aussie mortgage broker business

I’ve had my GMB profile and website up and running for about 4 months now and am really not seeing any traction on my 3-pack but have started ranking 1st and 2nd page for my keywords “mortgage broker bella vista” and “mortgage broker kellyville” But when it comes to “mortgage broker near me” i’m not even in the top 20 most times for the 3 pack. I’ve just finished setting up a whole heap of new citations last week and not seeing any traction yet. How long roughly would you say it would take in a perfect circumstance?
