I am planning to self manage as well and since there aren't many managers in my area I will likely employ a similar strategy once I decide to outsource the management.

One of the biggest factors in successful flips is building a strong team: contractors, agents, lenders, and property managers. 

I lived there for a couple years and I met this guy who has bought and managed a ton of property there. 

Investing in AZ, NV, ID, where you have family or friends that is a day away and you can start to build a network and team to help manage a property.  

If you can't manage what you currently have, you won't manage additional income from investments.

We just started managing 4 tiny homes on 1 lot with a shared pool and they are booking great at a rate commensurate with larger homes.   

This is the foundation of why LaPlante Real Estate is based in portfolio management and property management... my personal portfolio started in 2009 and I find the majority tends to be Section 8. 

Without accounting for management fees (I have not yet decided if I will try to self manage), and with planning to raise rents to typical market of $825 for each of the smaller units, and $1200 for the larger unit, does this seem like a worthy first investment? 

It's an estimated cash on cash return given current rental rates subtract expenses assuming 7% interest rate, 10% management fee, 5% repairs, 5% capex and other expenses like mortgage, insurance, tax. it's a estimate to tell you what properties to analyze vs ignoreyou can see the are pockets of negative returns as well as pockets of positive return. this is to supplement the data @Devin Conley provided

@Alec Barnes As the owner of a property management company in Texas, I completely agree that a solid screening process is essential for placing quality tenants.
