Yes, you're scaling now but more importantly, you can truly stop trading time for money and and start living your life on your on terms while building generational wealth for your family.

I'm located near Dallas and I'm ready to start my REI investment journey, preferably starting here in Dallas since it's where I live.

This property is in a great area for me in North Arlington (great schools, stones throw away from a huge community park, and close to I30), and the plan is to live in it for a year or so before renting it out (I’m sure I’ll be picking your brains when the time comes!). 

It currently covers all my living expenses, and when I move out would flow roughly $650 for me.

If you already own it and it was a personal residence that you don't want to sell providing you live somewhere in the area, have an interest and understanding of your local rental laws and aren't in California (the laws) or Florida (the possibility of assessments) then self management is a possibility. 

More and more people are buying/living in an RV.

You don't say where you live now but if you have the flexibility why not consider buying a scary, run down house or 2 to 4 unit, renovating it and then living in one unit and leasing the others ? 

I am considering purchasing a SFH with an ADU in the backyard, with the plan of living in the SFH and renting the ADU. 

We live in the area we are investing currently.
