In addition, I am currently studying for my CPA and I am considering what area I plan to be a specialist in.

If you are wanting to add more properties, it probably makes sense to pay the regular payment and save additional cash for other opportunities.  

An all cash, no loan transaction).For this reason, I calculate both cash on cash vs. total yearly return on my out of pocket money (which includes the down payment).Also note that usually you pay the first month of the mortgage in addition to the down payment, plus the whole of the insurance and (some) taxes at closing.

You need to walk the property, get a good sense of the neighborhood.

Not working more hours than that (750) for any other income.Then I realized that when managing multiple properties there are additional rules and to get around it one can permanently elect to treat them as one but then it could fire back when selling one of the properties... and then I am lost.Can you recommend prescriptive guidance on it?

Happy to provide additional information as needed.

Found a wonderful 12 unit brick comprised of 3 buildings within walking distance of UNCG.  

I was wondering about if there was anything I need to do in addition to just filling out the lease and getting the SSID ect...

Have an additional $100K for more acquisitions.

In addition to education, focus on networking and thinking of what you can bring to the table (if even it's small... bring your ideas) when you reach out to experienced investors.
