Renters who insist on owning Pitt bulls to me are just setting themselves up for poor accommodations most of the time.

SFR/MF, Class A/B/C/D, any special tenant accommodations?

I'm trying to get into the real estate investing game and am looking for a comprehensive guide/walk-through on different investing methods.

But needs to appease the seller who has been fairly accommodating until this point, and they just want their money. ( he has done 3-30 day extensions) I thought this was an opportunity to help him avoid capital gains and put some money to work in the mean-time.

Trust there are tons of things I didn't touch on so please don't take my response as comprehensive.

That said, you'll want to be very mindful of location: Many parts of Austell are in or near active floodplains, as evidenced by the catastrophic Flood of 2009 (https://www.weather.gov/ffc/atlanta_floods_anniv).The City of Austell Public Works Department provides comprehensive Floodplain Management services, including education, mapping, and many other resources, at https://www.apwsm.org.

The seller has been really accommodating and I think your angle might work with him. 

I also think that one could do very well doing Airbnb in Lynchburg as there is always a huge need for part time housing and visitors accommodations, again, due to Liberty.

Only you can truly take a comprehensive approach to your overall investments.

Withold more capital from the fundraising/profits to accommodate unforeseen issues like extra work, buyer's finance and taxes.
