I play way too many video games, which I probably need to quit doing so I can focus on important things. 

Should I be focused on building my credit and saving money only right now or is there a way to get into my first rental property to get my investments started?  

I've mailed out personal letter's so far that is focused towards sellers. 

Then sounds like you need to focus more on networking...

You are a new agent and should not focus on commissions, teams, solo, etc.

My wife and I have recently committed ourselves to taking the plunge into real estate investing, focusing on buy and hold rental units with the goal of generating monthly cash flow (flipping, hacking, wholesaling not an interest... right now).

Ultimately, I want to attract the highest quality tenants - IMO, your focus should be on that.

I was so focused on the acquisition side I never learned the most important part is the business side of getting the return for the next 20 years and that is where the rubber meets the road.

As far as networking, get on 2-3 Facebook groups that focus on target areas and investment strategies of interest.

Stay focused & keep feeling out your niches.
