Even without a budget for repairs/etc - let's just define "cashflow" as income left over after PITI & utilities for a moment - Mac Groveland and Highland Park are going to be tough.

Just from the little you wrote, it's pretty heavy on the red flags. 60 days on the market (depends where this is whether that is a lot or just fine, but definitely overpriced at this many days) plus no sold comps.

So as long as your insurance, property taxes, property management, utilities maintenance, repairs, vacancy, and capex come to $4/mo or less you’ll be fine.

Add utilities, lawn and pool care $800-1000.

Vacancy: 3 weeks every 2 years + utilities Make ready expenses: from $1000 to $5000 depending on house needs  

What are the expenses (taxes, who pays utilities, etc)?

I am a fan of utilizing equity in existing real estate owned to build the rental portfolio though at the beginning, rather than just relying on money saved alone.  

Multifamily is a smart goal, especially in military-heavy areas like Hinesville or Savannah.

I’m trying to utilize 1% rule and it’s tough with current market 

If you believe the area will appreciate heavy, I personally would opt for SFH.
