In terms of the next steps in your training, proficiently modeling real estate in Excel would be a priority, as all firms use Excel in some fashion to model real estate.
Depending on the firm, ARGUS training may or may not be helpful as well. My suggestion would be to review the requirements for the jobs you’re targeting and if ARGUS is a common requirement, then spend some time familiarizing yourself with ARGUS.
But even then, plan to allocate in terms of learning time 10 hours in Excel for every 1 in ARGUS.
