This is assuming there is even enough land on the property to install a mound which has to be located in a different spot than the already failed leach field.

Cool Courtney King we'll get a head count and choose a spot for tomorrow!

Even with GA was a mega hot spot for investors, it was still SFRs mostly. 

I think my major blind spot is that I can't even conceptualize something this size.

I want Jane to move her stanky hairdresser equipment so I can rent to a nice CPA who is so serene and predicable that it made Buddha cry sweet tears of jealousy. 

I'm considering folding b/c my husband has an ATL base starting in Nov so he no longer needs to commute to this location for work; AND it seems that our sweet spot niche is souring with a lot of cheaper competition...We did make one house a traditional rental with solid margins but the tenant quality isn't as good versus our niche and it has been a headache.

Personally, I am walking the properties with a contractor who can spot many issues and give me a quote on the cost to fix, then I can adjust my offer accordingly. 

Leveraging yourself with the majority of cash on hand can leave you in a bad spot.

My concern is that you seem fixated on "a 6-10 unit building", perhaps because you think that is where your sweet spot lies.

@James Canoy besides the stuff mentioned, we did about 40% of the floors, tons and tons of paint, some trim work, gutted and redid one bathroom and kitchen, replaced all the appliances, two water heaters, built a small shed for an oil tank, some capping on the roof, just a few spots for wall repairs, poured a walkway, and redid a lot of the plumbing lines (lots of leaks).
