Its hard to get the balance, but you could likely increase rates and keep the same net $$, but with less wear/tear on the properties.

We are charged 3% for every payment, plus $499/year subscription fee.  

It is for a 3BD (including master suite overlooking a lake), 3Bath, nice neighborhood.I'm trying to figure out the wear and tear I can expect from different prospective clients like:- Teenagers- Children- Boys vs. girls- Old vs. young- Extended family (e.g. grandma, mom, daughter in the house)- Other?

We are nervous as this will be our first investment and since both of us have full time careers, we are currently looking for a passive investment where we can invest with someone and learn from the bottom up.

We are starting to partner with other investors on projects, so the topic of finish comes to the table from time to time. 

If you're paying $700 a month, you get pissed and do everything u can to prevent getting dings.So the real value of section 8 vs not section 8 is the tenant and wear on your property.

We are trying to figure our options. 1 option is to sell it as is to another flipper and have them complete it.

We are looking into buying SFH's in Atlanta that have a basement, side 'apartment', and/or in-law suite as a creative way to generate rental income while owner occupying the property.

Sounds like we are in similar neighborhoods. 

You also have four individuals which increases the number of cars on the property, more visitors, higher likelihood of partying, more inter-personal relationship problems, more wear-and-tear, etc.
