@Tony S. : Great question!
Firstly, the most important thing for you to do: keep moving forward! You have a list of things to do. Make sure you're doing something on that list every day. On days you're not doing something on the list, spend some time reflecting on what's working and refining your list.
You correctly identified that the market is hot. That being the case, the most important thing to spend time on is deal-flow. Where are you sourcing your deals? Brokers or direct marketing? Either way, concentrate on activities that get deals on your desk. If it's brokers, make sure you're contacting them on a regular basis. If it's direct marketing, make sure your methods align with your goals, and you're doing activities which make your phone ring.
Don't wait to start vetting your team. The most important is your PM. Have a PM ready to go that fits your strategy. That will also help you source deals in that Brokers will take you more seriously if you're working with a PM that they've heard of, and hopefully so will lenders. second, start making contact with lenders to see what type of deals they like to do, and why terms they offer. They are all different, so you should know who to call for each kind of deal you may encounter.
Finally, have a general outline of what you will do when you land a deal. You don't need to know everything in advanced, but have a plan, and run it by us! If you don't have a plan, I can share one with you.
Hope that helps, and go get'em!
