I would check what the local zoning codes are first to be sure everything is in compliance.

Just throwing this out there as an owner of a 98-year old house, and with the admission that I am NOT a landlord or familiar with tenant laws there....Are the plumbing & electricity up to code?

What your local municipalities require for codes, rental registrations, whom to talk to.

They should be able to work out the couple of kinks Ive been having in automation as well as address the online application need.For every onewhile I've got a programmer doing some code work should I A: combine all of my steps into a single email that directs potential tenants to the pre screening page, they fill it out, if they answer correctly they are directed to the scheduler ORb: They get the first email that directs them to the pre screening page after they fill it out they get a second email directing them to my scheduler? 

Pulling permits means I would have to bring electrical up to code, possibly plumbing and who knows what else.  

Also, if your property is recent construction, code requirements will be much more stringent.

HelloCan anyone tell me which zip codes are good areas and which are bad in these 2 cities?

And many times they file a release of lien so they are no longer responsible for the property because of back taxes and code violations.

Lately, there has been a lot of activity in the zip code for several reasons (more people moving to Atlanta, new Braves stadium http://www.cbs46.com/story/26545193/new-atlanta-br..., good schools) which has caused the Median prices of homes to go up for example the Single Family Residence prices trends are belowMedian Prices in Oct 2013 for Single Family Homes was 165,000Oct 2014 for SFR was $194,000Median Sold price currently stands at- $232,500Average sold to OLP (original list price) price is - 93.7% So basically the prices are going up in the ZipCode.  

But going down to the city hall and pulling all properties that have either code or health violations.
