Newbie to notes from Nashville, TN

[Leonard Gunn, Jr]

Hello everyone. I have been involved in real estate since high school when my father had me crawling under houses pulling wire for the craftsmen. This was 45 years back. Since then I have been in and out of the game. I’ve been involved in 2 flips, 10 rentals, and 4 notes. At this stage I’m leaning towards notes. I read in different groups and forums the posts of locating notes & the mechanics of the note, however my questions are more basic than that - what infrastructure should I have in place (such as I've heard that I need an 800# & that then I don't); what type of business entity as I start out; software and hardware needed; to what services should I subscribe or be looking at as I grow? I'm just looking for answers so as to proceed professionally and correctly.

Thanks,
Leonard Gunn, Jr.
