That's helps you get more information regarding owners and property information. 

Once you reach E5 use the BAH base allowance for housing to start REI.  

I made a substantial down payment, so I could potentially pay off the house in about 4 years with my current income.

I’m currently in the process of building a house for the purpose of STR in the Shell Knob area.

It really depends on what types of rentals you hope to keep, if you're house hacking and flipping, etc.

The owner had been living in these conditions for a long time due to mental health issues.It was heartbreaking to see.We agreed on a price and closed very quickly to provide relief.

For notices, contact her through her normal method, but also post a notice on the house AND send a registered letter to the last known address.

I have one duplex and have been house hacking since I bought it, it's been 5 years plus I have this property and finally ready for a 2nd one, looking to see if I get another multi or a single family, any thoughts Side note I also need a bigger place since I have another child who now needs their own room.

But the best ways to get started are, in my opinion: 1) save up enough for a 10-20% down payment and then save a lot more on top of that for reserves, overages, and any unforeseen repairs.    2) have your financial house in order and have credit above 700 to get more favorable rate and terms from lenders.   3) speak to a loan officer that is experienced with fix and flips and get the necessary documents together for a pre approval (typically not much required, usually a valid ID, LLC docs if any, and two months of bank statements showing funds for down payment and reserves). 

You tend to see higher turnover when it's that small; good chance the property owner or property manager can't find people that a) only want 700 sq ft and b) are willing to sign a 5 year lease.
